Abstract: Objective:To study the effect and level of attraction of pheromone on Musca domestica.Methods:In laboratory the forced contact method was used to examine the quick killing effect and the mortality rate within 24 h,and the square box method was used to examine the effect of attraction.In field the effect of duration of two insecticides was observed.Results:KT⁵⁰ was 2.17 min and 1.92 min for carbamate and organophosphorus smear insecticide respectively,and the mortality rate was 100% within 24 h for both smear insecticides.The number of Musca domestica within 30 min in the test of attraction was 22 for carbamate smear insecticides,12 for granular insecticides,and 3 for simple carbamate smear insecticides;23 for new-type organophosphorus smear insecticides,11 for granular insecticides,and 4 for simple new-type organophosphorus insecticides.Smear and granular insecticides were used in the field experiment to observe the effect of duration.In the records on the 1^st,5^th,10^th,20^thand 30 ^th day,the number of Musca domestica was 192,154,73,47 and 1 for carbamate smear insecticides,and 178,102,41,19 and 2 for granular insecticides;209,172,117,88 and 54 for new-type organophosphorus smear insecticides,and 160,146,105,50 and 24 for granular insecticides.Conclusion:Both smear insecticides had better quick killing effect and stronger attraction,and effect of attraction had been raised 5 times after attractant fortified in the smear insecticides.
