Abstract

DUET ultra-low volume (ULV) (1% parllethrin, 5% sumithrin) and Aqualuer ULV (20.6% permethrin), applied neat, diluted with mineral oil, and diluted with diesel oil by a truck-mounted thermal fogger (LongRay TS-95 model) was evaluated in the field against caged Aedes albopictus adults. The application of Aqualuer ULV was significantly more effective than DUET ULV (t = 12.1, df = 5, P < 0.001) without dilution. There were no significant differences between the applications of DUET ULV or Aqualuer ULV diluted 1:3 with mineral oil (t = 0.662, df = 5, P = 0.518) or with 1:3 of diesel oil (t = 1.19, df = 5, P = 0.251). The solvents (mineral oil and diesel oil) to dilute DUET and Aqualuer and sprayed by the truck-mounted thermal fogger did not result in significant differences in the mortalities of caged Ae. albopictus.
