title: Attractive Toxic Sugar Bait (ATSB) Mixed With Pyriproxyfen for Control of Larval Aedes albopictus (Diptera: Culicidae) Through Fecal Deposits of Adult Mosquitoes.
abstract: Studies were conducted to determine if pyriproxyfen, an insect growth regulator (IGR) added to attractive toxic sugar baits (ATSBs) and ingested by adult Aedes albopictus (Skuse), could be fecally disseminated into water to inhibit emergence of mosquitoes (EI). Experimental treatments consisted of four dilutions of pyriproxyfen (0.5, 1, 5, and 10 ppb) in ATSB, with attractive sugar bait (ASB) serving as the negative control. To ensure no tarsal transfer of the IGR, the experimental treatments were dispensed in collagen sausages. Mosquito excrement was collected on card stock at the bottom of the mosquito cages at 1, 4, 6, and 8 h during the study. There were no differences between the EI times at which the fecal cards were collected (F19,88=1.8, P = 0.1592). The highest dilution of pyriproxyfen in ATSB (10 ppb) inhibited mosquito emergence in the most amounts (57%), as compared with the EI of other pyriproxyfen dilutions: 0.5 ppb = 42%, 1 ppb = 34%, and 5 ppb = 46% (F19,88=1.8, P = 0.1592). This study demonstrates that pyriproxyfen can be fecally disseminated into water and control larvae through adult mosquito ingestion and excretion of pyriproxyfen in ASB.
