Bacteria were isolated and identified from three sources that produced oviposition stimulants and/or attractants of Aedes albopictus (Skuse). The sources from which the bacteria were identified were oak leaf infusion, larval rearing water, and soil-contaminated cotton towels. Ten bacteria species were identified from seven genera. The oviposition responses of Ae. albopictus to each bacteria species were examined in open-cup, binary choice assays. These assays measured the number of eggs that were oviposited by single females based on both contact chemical stimulation and attraction to volatiles. Attraction to bacterial isolates was measured using a binary sticky-screen assay. Bacterial isolates that significantly attracted Ae. albopictus were further analyzed using an electroantennogram (EAG). Volatiles were collected and the EAG responses of gravid females were measured. The role of bacteria in oviposition site selection by Ae. albopictus is discussed.
