EFFECTS OF 3 LARVICIDES ON THE PRODUCTION OF AEDES-ALBOPICTUS BASED ON REMOVAL OF PUPAL EXUVIAE

The production of adult Aedes albopictus from tires in northcentral Fl orida was monitored for 169 days by the daily removal of pupal exuviae . More than twice as many adults emersed from tires located in the sha de (1.74 adults/tire/day) compared to tires in the sun (0.64 adults/ti re/day). The effect of 3 larvicides on the production of adult Ae. alb opictus was evaluated. The fungal pathogen Lagenidium giganteum was in effective. A liquid formulation of Bacillus thuringiensis israelensis (Acrobe(R)) provided significant control for 47 days, whereas a slow-r elease pellet formulation of the insect growth regulator methoprene (A ltosid(R)) provided almost complete control for 116 days.
