                                Technical Abstract: Reaching endophilic Aedes aegypti mosquito vectors of dengue located in human residences with aerial ULV pesticide applications is a prominent complication in operational wide area public health mosquito control activities. We conducted separate trials with a military C-130 fixed wing aircraft fitted with a modular aerial spray system and with a Hughes MD 500D helicopter fitted with a high pressure spray system to apply Dibrom (naled) over simulated urban and rural residences on a military reservation in north central Florida against caged adult sentinel colony-reared Ae. aegypti mosquitoes. We placed sentinel mosquitoes in open and protected locations both inside and outside of residences and measured mortality following multi-swath aerial applications conducted with typical real-world operational parameters. However, meteorological conditions were cool to warm with moderate humidity, and not representative of the hot, high humidity typical of dengue endemic regions. Selected residences were partially closed up sealed to provide an additional challenge to the ULV spray. Dibrom from the C-130 application penetrated well-ventilated residences and caused limited mortality in sentinel mosquitoes inside several protected locations; mortality in protected and unprotected outdoor locations was substantially higher, and approached 100% in unprotected outdoor locations. Dibrom from the MD 500D application also penetrated well-ventilated residences and caused high mortality in many unprotected indoor and outdoor locations, but only caused limited mortality in one indoor and two outdoor protected locations. Potential effects on spray dispersion of different droplet size spectra from the two spray systems and of different air currents generated by the aircraft are discussed.
