The predominant mosquito species for the 2008 surveillance season was Coquillettidia perturbans with approximately 39% of the total specimens collected. Aedes vexans populations spiked in may areas along with other floodwater species with the tremendous amounts of rain received, especially in September. Culex spp. populations were also higher than average, and we recorded a record number (8) of positive WNV in these species this year. 854 pools of mosquitoes comprising 17,433 mosquitoes were sent into Jamaica Plain for testing.

 

Requests for service, especially adulticiding, showed a 6.2% increase over 2007 with a total of 9,966 calls. All requests for service this year totaled 10,650.

The predominant mosquito species for the week was Culex pipiens/restuans, with a 32% increase from week 34. Ae.vexans numbers have spiked nearly 30% after dropping over 75% last week, with Oc. canadensis showing similar numbers. With two weeks of below average rainfall floodwater species are expected to continue to diminish. Cq. perturbans numbers have continued a steady decline along with Cs. melanura. Service calls declined by 39% from week 34 but are still 221% higher than the 5 year average.
