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 15 year average (8,873 in 2017 v. 3,427 15 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 year’s 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.
