Epi Week #35 - 2016 General Statements | Central Mass Mosquito Control Project

West Nile Virus continues to dominate this mosquito season, with 154 WNV+ mosquito pools reported so far (though still below levels at this time in 2013). There were no changes to DPH’s WNV risk levels, so there remain 55 different municipalities in 7 different counties currently at a WNV risk of Moderate. Mosquito collections were down once again this week; as in previous weeks, this was due to a large decrease in collections of both Culex pipiens/restuans and Coquillettidia perturbans.

Weather

Drought conditions expanded slightly, with the majority of Berkshire County now at Moderate Drought (orange) status.

Epi Week 36 Drought Level Across MA

As you can see in the map below, Epi Week 35 brought at least some rain for most of the state, with the greatest accumulation around 1.5”, in a band reaching from eastern Hampden County up through Essex County. The remnants of Tropical Storm Hermine stalled and hung around for days longer than anyone was originally expecting, and even then the storm did not produce much precipitation; we’ll see the results in the Epi Week 36 report.
