“…After hanging all holding cups, the rack was placed in an insectary under controlled conditions. Mosquito mortality was recorded the next day, with permethrin tests read at 12 h (Sandoski et al , Crockett et al ), and malathion tests read at 18–20 h post‐treatment (Mount et al , ). These mortality reading times were checked at least yearly for same results as 24 h post‐treatment observations.…”

The ground adulticiding program in densely populated Harris County has been employed on the basis of virus-positive mosquitoes almost exclusively using the 'rotation of chemicals best practices' stratagem. To evaluate its effectiveness, 15 comparative field cage testing events were conducted from 2011-2015 using seven wild population samples from repeatedly collected locations of Culex quinquefasciatus Say and a laboratory susceptible Sebring strain colony reared to adults. A 3 x 3 plot design was employed for exposure to ultra-low volume applications of malathion and synergized permethrin. No significant differences were found in mortality rate among testing dates, year, row placement, or relative humidity. Mortality was significantly different between adulticides (p<0.001) with mean mortality rates for malathion 96.42% (±7.95%) and permethrin 92.38% (±14.04). There was a significant temperature difference for permethrin (p<0.001) but none for malathion (p=0.644). Mosquito population mortality was statistically different by study operational area (p<0.011) and chemical (p<0.001). Susceptible colony adults used as positive controls downwind strongly aided determination of efficacy and resistance to each adulticide, providing evidence of individual application coverage, though comparative analysis was done with overall mortalities by normal methodology.

Optimized aerial applications were conducted to assess the efficacy of 2 formulations of resmethrin (Scourge 18-54, Aqua-Scourge 10-30) for control of caged adult Anopheles quadrimaculatus. Micronair AU4000 rotary atomizers were employed to apply the chemical. Both compounds were applied at 0.0035 lb AI/acre (3.92 g AI/ha) with the use of the AGDISP computer model to predict appropriate flight offsets (up to 1,219.2 m). Efficacy was based on bioassays with caged An. quadrimaculatus adults and assessment of impinger-collected droplets. Both compounds provided effective mosquito control. Mean mortality at 24 h posttreatment averaged 80.4% for Scourge, and 80.7% for Aqua-Scourge. Mean droplet sizes, Dv0.5 = 26 microm and 38 microm, and mean density, 74 droplets/cm2 and 41 droplets/cm2, for Scourge and Aqua-Scourge, respectively, were consistent with the bioassay results. Analysis of droplet deposition and mortality failed to reveal a statistical correlation between mortality and deposit volume.

Against caged field-collected adults of Anopheles quadrimaculatus, optimized aerial applications of ANVIL 10+10 at 18.4 ml (1.63 g active ingredient)/0.4 ha produced a mean mortality of 92% at 1, 12, and 24 h after treatment. These trials were conducted with 7 stacked passes applied 1,067 m upwind of the target site when wind velocity was 18-21 km/h at an application altitude of 46 m and 5-10 km/h at groundlevel. When the wind velocity aloft was greater than might be operationally acceptable (27 km/h), reduced efficacy (64% mortality) was observed in the bioassay site (1,524 m downwind from 11 stacked passes) in an unreplicated application. Droplets from the 2 tail-mounted Beecomist 360-A-12-V rotary atomizers (fitted with wire sleeve cages of size 40 mesh) collected on spinning Teflon-coated slides in the target area averaged a volume mean diameter (VMD) of 29 microm and a droplet density of 39 droplets/cm2 in 18- to 21-km/h winds. With 27-km/h winds aloft and a greater application offset, the VMD and droplet density dropped to 23 microm and 18 droplets/cm2, respectively. Coupled with unreplicated results from a nonoptimized application, these tests provide further documentation of the efficacy of ANVIL 10+10 for wide-area adult mosquito control and for optimization technology.
