Abstract: The life tables grouped according to various factors,the index of population trend (I)and the interference index of population control(IIPC)were used as the basic sampling parameters to evaluate the controlling effects of eight common-used insecticides on the natural population dynamics of the citrus leaf-miner(CLM)Phyllocnstis citrella Stainton.Results indicate that petroleum oil,acetamiprid,imidacloprid,carbosulfan,lambda-cyhalothrine and dimthypo present better interfering effects on CLM.Among all the insecticides,97%petroleum oil EC applied with 1/500 concentration shows the best controlling effects on the population dynamics of the CLM,its index of population trend(Ⅰ) of the CLM decreases to 0.0055 from 5.3412 of the control,and its IIPC is 0.0010.The IIPC of 3% acetamiprid EC applied with 1/2000 concentration,10%imidacloprid WP applied with 1/3000 concentration,20% carbosulfan EC applied with 1/2000 concentration,2.5% lambda-cyhalothrine EC applied with 1/2000 concentration,18% dimthypo AS applied with 1/1500 concentration,5% chlorfluazuron EC applied with 1/4000 concentration and 48% chlorpyrifos EC applied with 1/3000 concentration are 0.0025,0.0026,0.0103,0.0273,0.0811,0.4305 and 0.5454,respectively.According to the above results,petroleum oil is suitable for the pesticide application guideline for green food production.Acetamiprid,imidacloprid,carbosulfan,lambda-cyhalothrine and dimthypo could be selected as alternative insecticides.Chlorpyrifos and chlorfluazuron are not advocated to control CLM in the grove.
