抄録: A field experiment was conducted to examine the duration of complete inhibition of adult emergence of Aedes albopictus at 3 different concentrations of pyriproxyfen (0.1, 1, and 10ppm). Forty plastic containers with 1,000ml of water were placed as ovi-traps at the campus of Nagasaki University School of Medicine on 1 June 1993. Twenty-five ovi-traps were treated with 0.1, 1, and 10ppm of pyriproxyfen and 15 ovi-traps were left without treatment as the control. Pupae of naturally breeding Ae. albopictus were collected from the ovi-traps 3 times a week from June to October and the percentage of adult emergence was examined in the laboratory. The emergence of adults was inhibited completely during the whole study period at the highest concentration of 10ppm, whereas the complete inhibition of emergence was never observed at the lowest concentration of 0.1ppm. The negative correlation between the concentration of pyriproxyfen and the density of puape was observed in the whole experimental period, except the late October. The minimum concentration of pyriproxyfen that results in the complete inhibition of adult emergence of Ae. albopictus during the whole breeding season was estimated around 1ppm in the field conditions in Nagasaki.
