Efficacy of pyriproxyfen, (4-phenoxypheny1(RS)-2-(2-pyridyloxy)propylether) granules against mosquito larvae was examined at a graveyard in Toyama, Japan. Three kinds of water holding containers were used in a survey area of 0.1ha; a round plastic container with a ceramic flowerpot in it, a similar container with a plastic flowerpot instead and a quarter section of used tire. Three liters of water were put into each container and pyriproxyfen granules were applied so as to give 1 or 3ppm concentration in the test containers. A total of 8 containers were placed in various parts of the graveyard. On the day 30, all mosquito larvae and pupae found in each container were collected and transferred to the laboratory at 27℃. During the following 20 days the number of adults emerged was counted and species were determined. The mosquitoes emerged were identified as Tripteroides bambusa, Uranotaenia bimaculata, Aedes japonicus and Aedes albopictus. The percent emergence was reduced in all containers with pyriproxyfen, and the lowest emergence rate (3.3%) was shown at 3ppm. The emergence of females Ae. japonicus and Ae. albopictus that bite humans, was inhibited to the same extent as of the total mosquitoes collected. Since this test was conducted at an open-air place, the pyriproxyfen might be diluted by rainfall or flowed into the humus and soil. Therefore its concentration might be changed from that set on the beginning of the test. However, it reduced the emergence of mosquitoes in such conditions, showing its effectiveness as an insect growth regulator.
