Abstract: In a 2m×4m×2m test Chamber,20、40、80、160 houseflies were tested respectively,the relationship of the knockdown rates of houseflies to fly electrocutor and the time logartihm presents "S" Pattern Model 1:Y=A+B1nt,(x=A+B1n^t-5)can/appropriately describe the relationship between probit KD rates, KD rates and time.Model 2:1_n(1-D/D)=a+b1ni,D=(1+e^a+b1nt)^-1 can effectively describe the relationship between KD rates and time. KT₅₀ and 24 hours KD rates calculated from the models can be used as indexes for fly electrocutor efficiency estimate.

摘要： 在2×4×2(m³)的模拟小室内,分别用20、40、80、160只家蝇受试,灭蝇灯对家蝇的击倒率与时间对数均呈S型曲线关系,模型1:y=A+B1nt,(x=A+B1n^t-5)能很好地描述击倒率机值及击倒率与时间的关系,其中直线回归的决定系数均在0.97以上;模型2:1_n(1-D/D)=a+b1ni,D=(1+e^a+b1nt)^-1能有效地描述击倒率与时间的关系,其中直线回归的决定系数均在0.95以上。由模型计算的KT₅₀、24h击倒率,可做为评价灭蝇灯灭效的指标。
