Abstract: We controled mosquito and fly with Pyriproxyfen and Sumithion-NP(made in Japan )in August to September, 1992 and have got better effects. At the season peak of the ,fly population quantity, the density came down from 167 ind./0.5h to 10 ind./0.5h after the first application(ULV spray), the decline rate of the density reached over 94%; After the second application, the decline rate reached 99.2%, and then during one month the density of fly larva was keeped below 0.22 ind./g, the decline rate of the density was keeped over 96.17%. After 2 months, it was found that newly the pupated pupae size were smaller, the distortional individuals appeared, the emergence rate was lower markedly, under 6.54%. We also have made obvious kill effect on Culex pipiens pallens with pyriproxyfen in the field experiment.The decline rate of larvae density reached 100% after 3 days, however the density came up after one week. when managed again,the decline rate reached 98.78% after 3 days.
