Evaluation of aerial and ground-applied adulticides against mosquito species in Arkansas and Louisiana.
Mosquitoes were subjected to ultra-low volume (ULV) aerial applications of permethrin synergized with piperonyl butoxide (Biomist 30:30. Biomist 31:66) and Cythion and ULV ground applications of permethrin synergized with piperonyl butoxide (Biomist 30:30. Biomist 12:60), resmethrin (Scourge), and sumithrin (Solo 40-OS and Duets 8.8-OS). Permethrin compounds tested aerially against Anopheles quadrimaculatus were not significantly different. Biomist 30:30 tested aerially against Culex quinquefasciatus did provide significantly greater mortality compared to Cythion. Biomist 30:30 and Biomist 31:66 tested aerially against An. quadrimaculatus at 1 h did not provide a significant difference up to 600 ft. (182.9 m). Both products ground tested at 24 h revealed nonsignificant results. Biomist 30:30 and Biomist 12:60 ground tested against Cx. quinquefasciatus at 1 h did not provide a significant difference at 100 ft. (30.5 m) or 200 ft. (61.0 m); however, significantly greater mortality was observed at 300 ft. (61.0 m) and 600 ft. (91.4 m). At 24 h no significant mortality differences were observed at 300 ft. (61.0 m) and 600 ft. (91.4 m). Anopheles quadrimaculatus and Psorophora columbiae were treated with a 1:1 mixture of Solo 40-OS and Duet 8.8-OS (sumithrin+piperonyl butoxide). Significant mortality differences (P < or = 0.05) between species at 1 h posttreatment occurred at 300 ft. (91.4 m).
