Abstract/OtherAbstract:
Adult mortality of Anopheles quadrimaculatus, Culex quinquefasciatus, and the Aedes spp. complex (Aedes sollicitans and Aedes taeniorhynchus) was observed after aerial ultra-low volume (ULV) exposure to Dibrom, Trumpet, and Scourge. Dibrom was applied at 112 g active ingredient (AI)/ha, Trumpet at 112 g AI/ha, and Scourge at 1.96 g AI/ha. At all time intervals, Dibrom and Trumpet were significantly more effective against the Aedes spp. complex than against An. quadrimaculatus and Cx. quinquefasciatus. Scourge was significantly more effective against An. quadrimaculatus and Cx. quinquefasciatus than Dibrom or Trumpet. Trumpet was evaluated at lower labeled rates (28, 56, and 84 g AI/ha) against Cx. quinquefasciatus and the Aedes spp. complex. Adult mortality with Trumpet increased significantly at 1 and 24 h against Cx. quinquefasciatus. With the Aedes spp. complex, mortality increased with rate at 1 h, but at 12 and 24 h, the medium and high dosages were not significantly different from each other. Culex quinquefasciatus and the Aedes spp. complex were also subjected to ULV ground applications of Dibrom, Trumpet, and Scourge. Dibrom was applied at 22.4 g AI/ha, Trumpet at 22.4 g AI/ha, and Scourge as a 1:6 mineral oil mixture at 1.96 g AI/ha. Relative to Dibrom and Trumpet, mortality from Scourge differed greatly with mosquito species. Against Cx. quinquefasciatus, Scourge was significantly more effective than Dibrom and Trumpet at all times and distances, but against the Aedes spp. complex Scourge was significantly less effective.
