Epi week 27 narrative:


The temperatures for EPI week 28 averaged approximately 1.61 degrees cooler than the previous week, with 0.53 inches of precipitation observed. Overall collection numbers increased by 63.01% from EPI week 27, with all target species increasing from the prior collection with the exception of Ochlerotatus canadensis. 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 remains 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 201% more service requests than the 14 year average (12,662 in 2017 v. 6,334 14 yr. avg.), and 4.4% more than this time in 2016 (12,662 in 2017 v. 12,127 in 2016). Service requests dropped 20% from Epi week 28 v week 27. 585 service requests were received and 1,818 requests were performed in Epi week 28 with favorable weather conditions all week.
