Abstract

Malathion and Fendona® (alphacypermethrin) insecticides were tested against larvae and adult stages of house flies, Musca domestica Linnaeus. The percentage mortality of House flies larvae range between 0% and 100%at different exposed dose rate of tested insecticide. Probit analysis was used to determine the LD50. The value LD50 for malathion without food medium was 0.833 -l/larvae and treatment with food medium was 0.895 -l/larvaerespectively. The LD50 for Fendona® without food medium was 0.545 -l/larvae and 0.870 -l/larvae for treatment with food medium. The LD50 values for Fendona® in both treatment was lowers compared with malathion, which meansthat alphacypermethrin is more toxic than malathion. Different with the test on adult house flies, the knockdown time values for alphacypermethrin at KT50 is 9.876 minutes and KT95 is 20.495 minutes against female adult house fliesand were significantly lower than malathion (KT50 is 75.17 minutes and KT95 is 103.38 minutes respectively). Result also showed that a total of 1.0-l of Fendona® is reacting more effective than 1.0-l of malathion. Therefore, we canconclude that Fendona® is the most effective insecticide towards larvae and adult stage of M. domestica. The effectiveness of both chemicals was affected when treated larvae was in the rearing medium
