1) The comparative effect of organophosphorus, pyrethroid, IGR and Bti insecticides to larvae of a moth fly Clogmia albipunctatus was studied in laboratory conditions. 2) The dilution immersion test to 4th inster larvae, showed that pyriproxyfen was the most effective, followed by Bti, fenthion, etofenprox, temefos, fenitrothion and diazinon in order. 3) LC_<50> values obtained revealed that Clogmia albipunctatus larvae was extremely low susceptible against the insecticides used, showing relativery lower at 2～4 orders than Culex pipiens pallens larvae, but it doesn't seem to be considered the resistance to insecticides as the values were almost same as those of the former reports. 4) From the results of the present test, it was concluded that pyriproxyfen and Bti were expected for practical use at the minimum dosage rate of 1ppm (pyriproxyfen) or 3ppm (Bti) to the breeding place.
