The temperature for EPI week 39 averaged approximately 8.17 degrees cooler than the previous week, with 0.65 inches of precipitation observed. At the CMMCP historical surveillance trap sites, the overall collection numbers decreased (-67.48%) over EPI week 38. All target species experienced reductions in population this surveillance period. The long-term surveillance locations once again showed an overall increase when compared to the 2015 season. Elevated levels of Aedes vexans influenced this yearly change. Culex species are currently the most abundant target mosquito in the CMMCP service area, with Ae. vexans the second most abundant species once again. This was the final week of mosquito surveillance for the 2016 season. Thirty egg papers were collected from CMMCP ovitraps this week. These produced only 14 eggs which will help gauge the presence of Aedes albopictus in central Massachusetts. No identifications of Ae. albopictus have been confirmed in 2016.

No virus confirmations were confirmed in Epi week 38.

 

For the year we received 153% more service requests than average; 15,281 requests compared to the 13 year average of 9,962. Routine adulticiding ended Sept. 1 due to decreasing service requests from residents and declining mosquito populations, but CMMCP work crews will be ready for arbovirus interventions as needed until the season ends.

 

Standard catch basin treatments totaling 79,618 have ended in all member communities. Our tire program has come off hiatus and we have begun collecting tires. We have 2 large tire piles to remove along with local stakeholder assistance, plus numerous curbside pickups have been scheduled and/or completed. Standard ditch maintenance jobs are lined up in all districts and projects have begun in earnest; all scheduled low flow maintenance projects with the excavator have been completed by the ACOE deadline of October 1.

The predominant mosquito for the week was Culex pipiens/restuans followed by Aedes vexans

 

*Low late season numbers may contribute to these comparisons being not as significant as they appear

 

The temperature for EPI week 38 averaged approximately 2.30 degrees warmer than the previous week, with 1.22 inches of precipitation observed. The majority of this precipitation occurred in a single sustained rain event. At the CMMCP historical surveillance trap sites, the overall collection numbers increased (+10.81%) over EPI week 37. An increase of Culex species was primarily responsible for this slight growth in mosquito specimens. Culex species and Ochlerotatus canadensis were the only target mosquitoes to increase in population this surveillance period. The long-term surveillance locations once again showed an overall increase when compared to the 2015 season. Elevated levels of Culex species and Aedes vexans influenced this yearly change. Culex species are currently the most abundant target mosquito in the CMMCP service area, with Ae. vexans the second most abundant species once again. Cool evening temperatures will likely impact surveillance collections for EPI week 39. Ten egg papers were collected from CMMCP ovitraps this week. These produced 123 eggs which will help gauge the presence of Aedes albopictus in central Massachusetts. No confirmation of this invasive species have been detected in our service area in 2016.

Three virus confirmations (all WNV) were received from Epi week 36, resulting in ULV application in Epi week 37 in Auburn & Berlin, with an application scheduled in Millbury in Epi week 38. The areas in Auburn & Berlin were sprayed September 15 after consultation with the LBOH. Catch basins were treated and/or retreated in the affected areas. Enhanced adult mosquito surveillance was performed.

 

For the year we received 153% more service requests than average; 15,281 requests compared to the 13 year average of 9,962. Routine adulticiding ended Sept. 1 due to decreasing service requests from residents and declining mosquito populations, but CMMCP work crews will be ready for arbovirus interventions as needed until the season ends.

 

Standard catch basin treatments (currently totaling 75,890) will continue in all member communities and will end this week. With scattered reports of rain in our region, we have been pushing the message through social media and other outlets to Dump and Drain to minimize larval populations that use these habitats to develop. Our tire program has come off hiatus and we have begun collecting tires. We have 2 large tire piles to remove along with local stakeholder assistance, plus numerous curbside pickups to be scheduled. Standard ditch maintenance jobs are lined up in all districts and will begin in a few weeks, and we have begun some low flow maintenance projects with the excavator that will need to be completed by October 1 as per Army Corps regulations.

The predominant mosquito for the week was Culex pipiens/restuans. followed by Aedes vexans

 

*Low late season numbers may contribute to these comparisons being not as significant as they appear

 

The temperature for EPI week 36 averaged approximately 0.37 degrees cooler than the previous week, with only 0.33 inches of precipitation observed. At the CMMCP historical surveillance trap sites, the overall collection numbers decreased (-76.48%) over EPI week 35. A large decrease in Aedes vexans and Coquillettidia perturbans largely accounted for this drop in mosquito specimens. The only target species to increase in population this surveillance period was Culiseta melanura, although this increase represented only a few individuals over a very low previous week for the species. The long-term surveillance locations once again showed an overall increase when compared to the 2015 season. The elevated levels of Culex species and Ae. vexans influenced this yearly change. Culex species are currently the most abundant target mosquito in the CMMCP service area, with Ae. vexans now the second most abundant species, replacing Cq. perturbans. Fifteen egg papers were collected from CMMCP ovitraps this week. These produced only 27 eggs which will help gauge the presence of Aedes albopictus in central Massachusetts. No Ae. albopictus eggs have been identified this season.

One virus confirmation (WNV) was received in Epi week 36 in Millbury. The area was sprayed September 8 after consultation with the LBOH. The Boylston WNV application was delayed by the LBOH to get the word out to the public. Impacts from TD Hermine delayed the application and it was done Sept. 8. Catch basins were treated or retreated in the affected areas. Enhanced adult mosquito surveillance was performed.

 

For the year we received 153% more service requests than average; 15,281 requests compared to the 13 year average of 9,962. Routine adulticiding ended Sept. 1 due to decreasing service requests from residents and declining mosquito populations, but CMMCP work crews will be ready for arbovirus interventions as needed until the season ends.

 

Standard catch basin treatments (currently totaling 72,907) will continue in all member communities and will wind down next week. With scattered reports of rain in our region, we have been pushing the message through social media and other outlets to Dump and Drain to minimize larval populations that use these habitats to develop. Our tire program has come off hiatus and we have begun collecting tires. We have 2 large tire piles to remove along with local stakeholder assistance, plus numerous curbside pickups to be scheduled.

The predominant mosquito for the week was Culex pipiens/restuans. followed by Coquillettidia perturbans

 

The temperature for EPI week 35 averaged approximately 2.43 degrees cooler than the previous week, with zero significant precipitation observed. At the CMMCP historical surveillance trap sites, the overall collection numbers increased (+58.25%) over EPI week 34. This was due primarily to an increase in Aedes vexans and Coquillettidia perturbans, but additionally there was a large emergence of Psorophora ferox.

 

All other target species decreased in population this surveillance period. The long-term surveillance locations once again showed a significant overall increase when compared to the 2015 season. The elevated levels of Cq. perturbans and Ae. vexans influenced this yearly change. Culex species are currently the most abundant target mosquito in the CMMCP service area, with Cq. perturbans the second most abundant mosquito. Twenty-five egg papers were collected from CMMCP ovitraps this week. These produced 262 eggs which will help gauge the presence/absence of Aedes albopictus in central Massachusetts. No Ae. albopictus has been identified in our service area in 2016.

Four virus confirmations were received in Epi week 35, in Auburn, Boylston, Millbury and Westboro. Auburn and Westboro were sprayed September 1 after consultation with the LBOH, and the Millbury area was previously treated. Boylston asked to wait until Epi week 36 for an application to get the word out to the public. Impacts from TD Hermine may affect/delay the application. Catch basins were treated or retreated in the affected areas. Enhanced adult mosquito surveillance was performed.

 

For the year we received 153% more service requests than average; 15,281 requests compared to the 13 year average of 9,962. Service requests decreased 43.2% from the previous week; 261 in Epi week 35 compared to 374 in Epi week 34. Routine adulticiding ended Sept. 1 due to decreasing service requests from residents and declining mosquito populations, but CMMCP work crews will be ready for arbovirus interventions as needed until the season ends.

 

Standard catch basin treatments (currently totaling 67,687) will continue in all member communities and will wind down soon. With scattered reports of rain in our region, we have been pushing the message through social media and other outlets to Dump and Drain to minimize larval populations that use these habitats to develop. Our tire program has come off hiatus and we have begun collecting tires. We have 2 large tire piles to remove along with local stakeholder assistance, plus numerous curbside pickups to be scheduled. Standard ditch maintenance jobs are lined up in all districts and will begin in a few weeks, and we have begun some low flow maintenance projects with the excavator that will need to be completed by October 1 as per Army Corps regulations.

The predominant mosquito for the week was Culex pipiens/restuans. followed by Coquillettidia perturbans

 

The temperature for EPI week 34 averaged approximately 3.20 degrees cooler than the previous week, with almost 0.92 inches of precipitation observed. At the CMMCP historical surveillance trap sites, the overall collection numbers continued to decrease (-48.07%) over EPI week 33. This was due primarily to a decrease in Coquillettidia perturbans and Culex mosquitoes. Of the target species, only Aedes vexans increased in population this surveillance period. Despite the decrease from EPI week 33, the long-term surveillance locations once again showed a significant overall increase when compared to the 2015 season. The elevated levels of Cq. perturbans and Ae. vexans influenced this yearly change. Culex species are currently the most abundant target mosquito in the CMMCP service area, with Cq. perturbans the second most abundant mosquito. Thirty-five egg papers were collected from CMMCP ovitraps this week. These produced 1,929 eggs which will help gauge the presence of Aedes albopictus in central Massachusetts. This was the largest weekly collection of eggs from ovitraps this year.

The predominant mosquito for the week was Culex pipiens/restuans. followed by Coquillettidia perturbans

 

The temperature for EPI week 33 averaged approximately 0.15 degrees cooler than the previous week, with almost 0.44 inches of precipitation observed. At the CMMCP historical surveillance trap sites, the overall collection numbers continued to decrease (-47.72%) over EPI week 32. This was due primarily to another decrease in Coquillettidia perturbans. Of the target species, Aedes vexans, Culiseta melanura, and Culex increased in population, while Cq. perturbans and Ochlerotatus canadensis decreased this surveillance period. Despite the decrease from EPI week 32, the long-term surveillance locations once again showed a significant overall increase when compared to the 2015 season. The elevated levels of Cq. perturbans influenced this yearly change. Culex species are currently the most abundant target mosquito in the CMMCP service area, with Cq. perturbans the second most abundant mosquito. Five egg papers were collected from CMMCP ovitraps this week. These produced 147 eggs which will help gauge the presence of Aedes albopictus in central Massachusetts.

The predominant mosquito for the week was Coquillettidia perturbans followed by Culex pipiens/restuans.

 

The temperature for EPI week 32 averaged approximately 5.12 degrees warmer than the previous week, with only almost 0.75 inches of precipitation observed. At historical surveillance trap sites, the overall collection numbers decreased by 67.31% over EPI week 31, primarily due to a decrease in Coquillettidia perturbans. All target species decreased for EPI week 32. Despite the decrease from EPI week 31, the long-term surveillance locations showed a significant overall increase when compared to the 2015 season, due again primarily because of the change in the Cq. perturbans population. This species was once again the most abundant target mosquito in the CMMCP service area, with Cx. pipiens/restuans the second most abundant mosquito. Cq. perturbans will likely remain the predominant species for EPI week 33. Fourteen egg papers were collected from fifteen CMMCP ovitraps this week. These produced 941 eggs which will help monitor for the presence of Aedes albopictus in central Massachusetts.

Our first confirmation of West Nile Virus were in the towns of Auburn & Hopkinton on August 10. After consultation with the local Boards of Health, spraying was done in the affected areas August 11. Catch basins treatments were performed in these areas as necessary. Confirmation of WNV in nearby Grafton (a non-member town) on August 12 has prompted our surveillance team to determine if additional trapping is necessary in the bordering towns of Millbury & Shrewsbury.

 

For the year we received 159% more service requests than average; 14,340 requests compared to the 13 year average of 9,012. Service requests increased 5.3% from the previous week; 470 in Epi week 32 compared to 446 in Epi week 31.

 

Standard catch basin treatments continue in all member towns. With scattered reports of rain, some heavy, in our region, we have been pushing the message through social media and other outlets to Dump and Drain to minimize larval populations that use these habitats to develop.

The temperature for EPI week 31 averaged approximately 7.00 degrees cooler than the previous week, with only almost 0.71 inches of precipitation observed. At historical surveillance trap sites, the overall collection numbers increased by 10.02% over EPI week 30, primarily due to an increase of Coquillettidia perturbans. The only target species to experience a decrease for EPI week 31 was Culex pipiens/restuans. The long-term surveillance locations showed a significant overall increase when compared to the 2015 season, due again primarily because of the change in the Cq. perturbans population. This species was once again the most abundant target mosquito in the CMMCP service area, with Cx. pipiens/restuans the second most abundant mosquito. Cq. perturbans will likely remain the predominant species for EPI week 32. Ten egg papers were collected from fifteen CMMCP ovitraps this week. These produced 524 eggs which will help monitor for the presence of Aedes albopictus in central Massachusetts.

 

For the year we received 160% more service requests than average; 13,870 requests compared to the 13 year average of 8,648. Service requests decreased 31.3% from the previous week; 586 in Epi week 30 compared to 446 in Epi week 31.

The temperatures for EPI week 30 averaged approximately 1.90 degrees warmer than the previous week, with only almost 0.20 inches of precipitation observed. At historical surveillance trap sites, the overall collection numbers decreased by 43.54% over EPI week 29, primarily due to a significant reduction in Coquillettidia perturbans. The only target species to experience an increase for EPI week 30 was Culex pipiens/restuans. Although collection numbers decreased from the previous week, these long-term surveillance locations showed an overall increase when compared to the 2015 season. Cq. perturbans was once again the most abundant species in the CMMCP service area, with Cx. pipiens/restuans the second most abundant mosquito. Cq. perturbans will likely remain the predominant species for EPI week 31. Twelve egg papers were collected from fifteen CMMCP ovitraps this week. These produced 632 eggs which will help monitor for the presence of Aedes albopictus in central Massachusetts.

 

For the year we received 164% more service requests than average; 13,424 requests compared to the 13 year average of 8,169. Service requests decreased 21.3% from the previous week; 711 in Epi week 29 compared to 586 in Epi week 30.

 

Standard catch basin treatments continue in all member towns. With scattered reports of rain, some heavy, in our region, we have been pushing the message through social media and other outlets to Dump and Drain to minimize larval populations that use these habitats to develop.

The temperatures for EPI Week 29 averaged 2.74 degrees warmer than the previous week, with approximately 0.46 inches of observed precipitation. At historical surveillance trap sites, the overall collection numbers increased by 58.89% from EPI week 28. The changes in target species varied this week, with Coquillettidia perturbans and Culex pipiens/restuans having experienced increases, while Culiseta melanura and Ochlerotatus canadensis were observed in lower numbers. Coquillettidia perturbans was once again the most abundant species in the CMMCP service area, with Cx. pipiens/restuans the second most abundant mosquito. Cq. perturbans will likely remain the predominant species for EPI week 30.

 

Although CMMCP collected 5 ovitraps this week, the egg papers did not produce any eggs for enhanced surveillance of Aedes albopictus.

 

For the year we received 166% more service requests than average; 12,838 requests compared to the 13 year average of 7,703. Service requests increased 15.47% from last week; 614 in Epi week 28 compared to 711 in Epi week 29.

 

With the isolations of WNV in the city of Worcester, catch basins were treated (or retreated) in all member communities that border the city; Auburn, Millbury and Shrewsbury. Adult mosquito surveillance was enhanced in these bordering communities and results from Epi week 29 were negative. Standard catch basin treatments have begun in all member towns.

Despite the overall decrease from EPI week 26, the long-term surveillance locations showed an overall increase compared to the 2015 season. Cq. perturbans was once again the most abundant species in the CMMCP service area, with Oc. canadensis the second most abundant mosquito. Cq. perturbans will likely remain the predominant species for EPI week 28. The CMMCP service area did receive precipitation which may contribute to the emergence of some floodwater/container species.

 

For the year we received 178% more service requests than average; 11,513 requests compared to the 13 year average of 6,468. Service requests decreased 45.9% from last week; 1,026 in Epi week 26 compared to 703 in Epi week 27. With the isolations of WNV in the city of Worcester, catch basins were treated (or retreated) in all member communities that border the city; Auburn, Millbury and Shrewsbury. Adult mosquito surveillance will be enhanced in these bordering communities. Catch basin treatments will continue in all member towns shortly.

*Low early season numbers may contribute to these comparisons being not as significant as they appear.

 

The temperatures for EPI week 26 averaged approximately 2.99 degrees warmer than the previous week, with only 0.12 inches of precipitation observed. Overall collection numbers increased by 156.8% from EPI week 25. All target species displayed increases from the prior collection period except for Culex spp. and Aedes vexans. Culiseta melanura and Coquillettidia perturbans experienced the largest weekly increases. Cq. perturbans remains the most abundant species in the CMMCP service area, with Ochlerotatus canadensis now becoming the second most abundant. Cq. perturbans will likely remain the predominant species for the majority of the season. Despite the large population currently, this species may still experience further emergence. After observing the first Aedes vexans specimens of the season last week, none were found this collection period. The CMMCP service area has still not recently experienced any significant rain events.

 

For the year we received 186% more service requests than average; 10,810 requests compared to the 13 year average of 5,804. Service requests decreased slightly (1.9%) from last week 1,046 in Epi week 25 compared to 1,026 in Epi week 26. Early season catch basin treatments were performed in 2015 WNV virus areas, as well as in our inner cities, totaling 23,538. Basin treatments will continue in a few weeks. Our tire collection and ditch maintenance programs are currently on hiatus.

The temperatures for EPI week 25 averaged approximately 2.27 degrees warmer than the previous week, with only 0.07 inches of precipitation observed. Overall collection numbers increased by 326% from EPI week 24, with all target species displaying increases from the prior collection period. Those targets with the largest weekly increases were Culiseta melanura, Coquillettidia perturbans, and Culex. Cq. perturbans remains the most abundant species in the CMMCP service area, with Culex species now becoming the second most abundant. Cq. perturbans will likely remain the predominant species for the greater part of the season. Continued emergence of Cq. perturbans should also cause the overall collections numbers to increase. A small number of Aedes vexans were collected in EPI week 25, marking the first observation of this species this season. Floodwater species of mosquitoes will remain suppressed until the area experiences a significant precipitation event.

 

For the year we received 192% more service requests than average; 9,784 requests compared to the 13 year average of 5,084. Service requests decreased slightly (7.7%) from last week 1,127 in Epi week 24 compared to 1,046 in Epi week 25.

The temperatures for EPI week 24 averaged approximately 3.25 degrees warmer than the previous week, with no significant precipitation observed. Overall collection numbers were lower than EPI week 23, with only Coquillettidia perturbans displaying increases from the prior collection period. Culiseta melanura, Ochlerotatus canadensis, and Culex spp. were all present in lower numbers from the previous week. Cq. perturbans has overtaken Oc. canadensis as the most abundant species in the CMMCP service area, with Oc. canadensis now becoming the second most abundant species. With additional emergence, Cq. perturbans should remain a predominant species for the majority of the season. Overall collections numbers will likely increase with further emergence of this species as well. Aedes vexans has yet to be collected by the CMMCP surveillance program this season.

The temperatures for EPI week 23 averaged approximately 3.4 degrees cooler than the previous week, with 1.20 inches of precipitation observed. Overall collection numbers were lower than EPI week 22, although higher than last season for the long-term historical trap sites. Culiseta melanura and Culex spp. experienced increases this week, as well as Ochlerotatus canadensis and Coquillettidia perturbans. Oc. canadensis was the most abundant species, followed by Cq. perturbans, which will likely continue to rise over the next several collection periods. Overall collections numbers should increase with additional emergence. Aedes vexans has not been collected yet, although a recent significant rain event may contribute to the potential development of this species

The predominant mosquito for the week was Ochlerotatus excrucians followed by Ochlerotatus aurifer.

 

*Low early season numbers may contribute to these comparisons being not as significant as they appear

 

This was the first week of the 2016 CMMCP Mosquito Surveillance Program. The temperatures for EPI week 22 averaged 66.9F, which was approximately one degree cooler than the previous week. It also rained 0.41 inches, putting the final precipitation total for the month of May at 2.25 inches. The vast majority of specimens collected were from early season species such as Ochlerotatus excrucians, Oc. abserratus, and Oc. aurifer. These three species accounted for almost 65% of all mosquitoes collected. Currently Oc. excrucians is the predominant species in the CMMCP service area, with Oc. aurifer second. Increases in temperature coupled with additional emergence will likely cause surveillance collection numbers to rise as the season continues. Specimens collected in EPI week 23 will be pooled for arbovirus testing by the MDPH.
