Weather Summary (Northborough, MA): The weather for this particular week averaged 58.76F with a recorded high temperature of 81.90F and a recorded low temperature of only 39.30F. For this week there was also a total of 0.03 inches of rain observed. Compared to the previous week, it was approximately 8.37F cooler on average, and rained about 1.17 inches less. There has been 2.05 inches of rain accumulated in September, while the total rainfall for the month of August was 2.16 inches.

 

No arbovirus positives were noted by MDPH in Epi Week 38. The CMMCP staff is prepared if additional virus is confirmed in our service area and weather allows an adulticiding option.

 

The standard adulticide program responding to service calls from residents ended Sept. 5 due to substantially decreasing calls for this program; adult mosquito surveillance will continue and if virus is confirmed then response(s) including adulticiding if appropriate will be coordinated with state and local officials. The CMMCP work crews are performing ditch maintenance in low-flow areas, and the CMMCP tire collection program is back in full swing, with a collection event in Tewksbury netting 135 tires on Saturday Sept. 21. Holliston, Millbury and Wilmington have events scheduled over the next few weeks.

Weather Summary (Northborough, MA): The weather for this particular week averaged 67.1.F with a recorded high temperature of 94.0F and a recorded low temperature of only 41.3F. For this week there was also a total of 1.20 inches of rain observed. Compared to the previous week, it was approximately 0.29F warmer on average, and rained about 0.38 inches more. There has been 2.02 inches of rain accumulated in September, while the total rainfall for the month of August was 2.16 inches.

 

1 West Nile Virus collection was identified Sept. 10 in the CMMCP member community of Acton in Epi week 37 (collections from Epi week 36). After consultation with the Acton Board of Health, wide area spraying was performed on Sept 11 in the area of the virus confirmation. A second round of wide area spraying was done Sept. 10 and/or 11 in the 4 towns bordering Tyngsboro due to the EEE finding on Sept. 4. CMMCP officials met with the Tyngsborough Selectmen and Health departments on Sept. 9, but after expressing concerns about impacts to local honeybee populations and human impacts, as well as limited efficacy, the Board of Selectmen voted not to perform adulticiding in the recommend areas outlined by CMMCP. The CMMCP staff stands at the ready if additional virus is confirmed in our service area, and weather allows an adulticiding option.

 

The standard adulticide program responding to service calls from residents ended Sept. 5 due to substantially decreasing calls for this program; adult mosquito surveillance will continue and if virus is confirmed then response(s) including adulticiding if appropriate will be coordinated with state and local officials. The CMMCP work crews are performing one last round of larval control in their districts; ditch maintenance in low-flow areas is underway, and the CMMCP tire collection program is back in full swing, with collection events scheduled in Tewksbury, Holliston and Wilmington over the next few weeks.

Weather Summary (Northborough, MA): The weather for this particular week averaged 66.84F with a recorded high temperature of 79.6F and a recorded low temperature of only 42.7F. For this week there was also a total of 0.82 inches of rain observed. Compared to the previous week, it was approximately 4.07F cooler on average, and rained about 0.58 inches more. There has been 0.82 inches of rain accumulated in September, while the total rainfall for the month of August was 2.16 inches.

 

2 West Nile Virus collections were identified Sept. 4 in CMMCP member communities In Epi week 36 (collections from Epi week 35) in the towns of Blackstone & Tewksbury. After consultation with the respective Boards of Health, wide area spraying was performed on Sept 5. Also on Sept. 4 MDPH announced a horse was confirmed with EEE in the town of Tyngsborough (a non member town). The location of the horse in the southeastern part of town put it close to the Dracut, Chelmsford, Lowell and Westford town borders (all member communities). After consultation with each Board of Health, wide area spraying was done in these 4 towns Sept. 5, within a 1-2 mile radius of where the horse was stabled. CMMCP officials will be meeting with the Tyngsborough Selectmen and Health departments on Sept. 9, but concerns about impacts to local honeybee populations have already surfaced, and a wide area adulticide intervention is yet to be determined.

 

Yearly totals show we have received 47.7% more requests than average; 12,140 requests to date compared to the 10 year average of 8,215. Requests were 3.53% more than the 2012 totals; 11,725 in 2012 against 12,140 in 2013. Service requests dropped dramatically (57%) from EPI week 35 to Epi week 36 in 2013 (401 vs. 255). A majority of the service calls were from repeat callers, though some school systems and recreation departments request adulticide services on their properties.

 

The standard adulticide program responding to service calls from residents ended Sept. 5 due to substantially decreasing calls for this program; adult mosquito surveillance will continue and if virus is confirmed then response(s) including adulticiding if appropriate will be coordinated with state and local officials.

Weather Summary (Northborough, MA): The weather for this particular week averaged 71.10F with a recorded high temperature of 87.80F and a recorded low temperature of only 52.00F. For this week there was also a total of 0.00 inches of rain observed. Compared to the previous week, it was approximately 4.23F warmer on average, and rained about 0.02 inches less. There has been 1.92 inches of rain accumulated in August, while the total rainfall for the month of July was 2.85 inches.

 

West Nile Virus was identified in 2 CMMCP member communities In Epi week 34 (collections from Epi week 33), all in Culex mosquitoes. An application in Westboro was performed Aug. 21 & 22 after consultation with the local BOH. Additional surveillance traps were placed in the area. An application in Millbury is scheduled for Aug. 27 after consultation Millbury Board of Health. Additional surveillance is being gathered. Additional information on our vector events is available at this link: http://www.cmmcp.org/2013vector.htm. Press releases were issued by each community and numerous media outlets reported this information. Out catch basin program for the control of Culex larvae is winding down, with 50,893 basins treated to date in 40 member communities.

 

For the year we have received 43.9% more requests than average; 11,739 requests to date compared to the 10 year average of 8,153. Requests were 5.67% more than the 2012 totals for the same time frame, 11,109 in 2012 against 11,739 in 2013. Service requests increased 41% from EPI week 33 to Epi week 34 in 2013 (436 vs. 614) most likely due to increased media coverage of mosquito-borne virus confirmations.

West Nile Virus was identified in 3 CMMCP member communities In Epi week 33 (collections from Epi week 32), all in Culex mosquitoes. An application in Chelmsford was performed Aug. 15 after consultation with the local BOH. Additional surveillance traps were placed in the area, and catch basins were re-treated (initial treatments late May 2013). Applications in Boxborough and Shrewsbury are scheduled for Aug. 20 after consultation with the respective Boards of Health. Additional surveillance is being gathered; catch basins were just treated in the area in Shrewsbury, and Boxborough basins were treated Aug. 15. Additional information on our vector events is available at this link: http://www.cmmcp.org/2013vector.htm. Press releases were issued by each community, and numerous media outlets reported this information, with CMMCP staff participated in 3 interviews for print and/or television media.
