The field tests for control of Culex pipiens pallens bred in the drainage ditches by methoprene were conducted in Neyagawa City, Osaka Prefecture. Two trials were carried out. The first trial was in June, where it was rainy season, and there was continuous water flow in the drains. When sand granule form of methoprene was applied at 1ppm to such drainage ditches, the adult emergence of C. pipiens pallens was completely inhibited for the first 5 days, thereafter, the partial inhibition (more than 50% inhibition) of adult emergence lasted for 53 days. The second trial was carried out in August. At this time, the rainy season was over, and the water in the drainage ditches was in the stational condition. The inhibitory effect of sand granule form at the same dose lasted longer, up to 72 days after treatment. Whereas, one treatment with briquet form of methoprene, when applied at 1ppm, gave virtually almost complete inhibition of adult emergence for 30 days.
