Week 27 narrative:

 

The temperatures for EPI week 27 averaged approximately 2.87 degrees warmer than the previous week, with 0.54 inches of precipitation observed. Overall collection numbers increased by 12.54% from EPI week 26, with all target species increasing from the prior collection with the exception of Ochlerotatus canadensis and Culex. Compared to the 2016, all target species have been collected in lower numbers to this point in the season aside from Aedes vexans and Culex. Coquillettidia perturbans is now the most abundant mosquito in the CMMCP service area, with Culex the second most abundant. Cq. perturbans will likely remain the most abundant mosquito during the month of July. Early season mosquito species continue to decline as the season moves forward.

 

We have received 213% more service requests than the 14 year average (12,077 in 2017 v. 5,672 14 yr. avg.), and 4.8% more than this time in 2016 (12,077 in 2017 v. 11,513 in 2016). Service requests dropped 58% from Epi week 27 v week 26. 703 service requests were received and 1,376 requests were performed in Epi week 27 with favorable weather conditions and despite a shortened week due to the holiday.

Week 26 narrative:

 

The temperatures for EPI week 26 averaged approximately 6.16 degrees cooler than the previous week, with only 0.34 inches of precipitation observed. Overall collection numbers increased by 25.12% from EPI week 25, with the only target species increasing from the prior collection period being Coquillettidia perturbans. All other target species, Aedes vexans, Culiseta melanura, Culex, and Ochlerotatus canadensis, were collected in lower number from EPI week 25. Culex is now the most abundant mosquito in the CMMCP service area, with Cq. perturbans remaining the second most abundant. Cq. perturbans will likely become the most abundant mosquito during the month of July. Early season mosquito species continue to decline as the season moves forward.

 

We have received 227% more service requests than the 15 year average (11,374 in 2017 v. 5,005 15 yr. avg.), and 5.2% more than this time in 2016 (11,374 in 2017 v. 10,810 in 2016). Service requests dropped 25.1% from Epi week 26 v week 25. 1,111 service requests were received and 2,215 requests were performed in Epi week 26 with favorable weather conditions.

 

Early season catch basin treatments totaling 28,308 have ended in all member communities. We applied in last years WNV areas and continued into our urban centers. Standard in-season treatments will begin in a few weeks. Our tire program is on hiatus, but we collected 1,432 tires so far this year. Our ditch maintenance and beaver mitigation programs are also on hiatus but a few projects are planned for this summer.

The predominant mosquito for the week was Ochlerotatus canadensis followed by Coquillettidia perturbans.

 

Week 25 narrative:

 

The temperatures for EPI week 25 averaged approximately 2.59 degrees warmer than the previous week, with only 0.11 inches of precipitation observed. Overall collection numbers increased by 52.98% from EPI week 24, with Aedes vexans, Coquillettidia perturbans, and Ochlerotatus canadensis displaying increases from the prior collection period. Culiseta melanura and Culex were collected in lower number from EPI week 24. Oc. canadensis is now the most abundant species in the CMMCP service area, with Cq. perturbans becoming the second most abundant. Continued Cq. perturbans emergence should result in an overall increase of mosquitoes in the CMMCP service area. Several early spring mosquito species have begun to decline as the season moves forward. Aedes vexans, a floodwater species, are much higher this year than in the drought plagued 2016 season.

 

We have received 240% more service requests than the 14 year average (10,263 in 2017 v. 4,263 14 yr. avg.), and 4.8% more than this time in 2016 (10.263 in 2017 v. 9,784 in 2016). Service requests dropped 67.9% from Epi week 25 v week 24. 1,390 service requests were received and 1,812 requests were performed in Epi week 25 despite rain that cancelled some spray operations.

 

Early season catch basin treatments totaling 28,308 have ended in all member communities. We applied in last years WNV areas and continued into our urban centers. Standard in-season treatments will begin in a few weeks. Our tire program is on hiatus, but we collected 1,432 tires so far this year. Our ditch maintenance and beaver mitigation programs are also on hiatus but a few projects are planned for this summer.

The predominant mosquito for the week was Culex spp. followed by Ochlerotatus canadensis.

 

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

 

Week 24 Narrative:

 

The temperatures for EPI week 24 averaged approximately 12.16 degrees warmer than the previous week, with only 0.06 inches of precipitation observed. Overall collection numbers were significantly higher than EPI week 23, but lower than last season for the long-term historical trap sites. All target species experienced significant increases this week. Culex species was the most abundant mosquito, followed by Ochlerotatus canadensis. Coquillettidia perturbans has now been collected in the CMMCP surveillance traps and should continue to increase over the next several weeks. Overall collections numbers should also increase because of this additional Cq. perturbans emergence.

 

We have received 259% more service requests than the 14 year average (8,873 in 2017 v. 3,427 14 yr. avg.), and 1.5% more than this time in 2016 (8,873 in 2017 v. 8,738 in 2016). The standard adulticiding program is underway but rain and cool temperatures have cancelled some spray operations.

 

Early season catch basin treatments totaling 28,308 have ended in all member communities. We applied in last years WNV areas and continued into our urban centers. Standard in-season treatments will begin in a few weeks. Our tire program is on hiatus, but we collected 1,432 tires so far this year. Our ditch maintenance and beaver mitigation programs are also on hiatus but a few projects are planned for this summer.

Week 23 Narrative:

 

The temperatures for EPI week 23 averaged approximately 1.05 degrees warmer than the previous week, with 0.01 inches of precipitation observed. Overall collection numbers were lower than EPI week 22, and also lower than last season for the long-term historical trap sites. Culiseta melanura and Culex spp. experienced increases this week. Ochlerotatus canadensis was the most abundant species, followed by Ochlerotatus abserratus. Coquillettidia perturbans should begin to be collected in the CMMCP surveillance traps. Overall collections numbers will increase with additional emergence along with the high temperatures anticipated for EPI week 24.

 

During our first 2 weeks we received 255% more service requests than the 14 year average (6,539 in 2017 v. 2,564 14 yr. avg.), but 16.3% less than this time in 2016 (6,539 in 2017 v. 7,611 in 2016). The standard adulticiding program began June 5 but weather (rain and cool temps) cancelled the first 2 nights applications. 7 crews came in for overtime on Friday night to make up some of the backlog.

 

Early season catch basin treatments totaling 28,308 have ended in all member communities. We applied in last years WNV areas and continued into our urban centers. Standard in-season treatments will begin in a few weeks. Our tire program is on hiatus, but we collected 1,432 tires so far this year. Our ditch maintenance and beaver mitigation programs are also on hiatus but a few projects are planned for this summer.

Week 22 Narrative:

This was the first week of the 2017 CMMCP Mosquito Surveillance Program. The temperatures for EPI week 22 averaged 58.79F, which was approximately three degrees cooler than the previous week. It also rained 0.35 inches, putting the final precipitation total for the month of May at 4.68 inches. Currently Culiseta morsitans is the predominant mosquito in the CMMCP service area, with Culex species second. There were significant Ochlerotatus abserratus collected in the surveillance traps as well. 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.

 

During our first week we received 270% more service requests than the 14 year average, but 44% less than this time in 2016. The standard adulticiding program will begin June 5 weather permitting.

 

Early season catch basin treatments totaling 18,613 have begun in all member communities. We started in 2016 WNV areas, continued into our urban centers, and will spread out from there. Our tire program is on hiatus, but we collected 1,432 tires so far this year.
