Historical mosquito problem
During the Corps of Discovery, Lewis & Clark encountered mosquitoes near Williston in
August 1806
Clark left Lewis a note:
“Game scarce, mosquitoes troublesome”

Etofenprox
Etofenprox molecule identified in the early ’80s in Japan
Similar mode of action to traditional pyrethroids (sodium channel blocker)
Low mammalian toxicity (LD50 > 42,000 mg/kg) Registered for mosquito control Sept 2008
(Zenivex) Registration was supported by DWFP grant ZenivexE20 aerial label, requires
conformational data for US EPA

Conclusions
Zenivex was a easy to work with material: noncorrosive and flushed with BVA oil
Low toxicity makes it appealing
Effective at mid-level rate in high mosquito density environment
Price?

Future plans
Strategies for increasing the period of mosquito relief include:
Increase surveillance and scouting to determine larval development sites and larvicide these areas
Increase adult surveillance to determine optimum application time
Increasing the size of the spray area to create a buffer zone around Williston
Consider applications on Army Corps land Multiple applications Begin at dusk for adulticide sprays
