摘　　要：柑橘潜叶蛾,作为柑橘类果树的主要害虫之一,其危害程度和防治难度一直备受关注。本研究采用浸叶法对桂林地区柑橘潜叶蛾种群进行了室内毒力测定和田间药效试验,室内毒力测定结果表明:其LC_(50)值啶虫脒>阿维菌素>甲氰菊酯>高效氯氟氰菊酯,田间药效试验结果表明:药后1 d、10 d和20 d时,20%啶虫脒WP 10000倍液防效>25 g/L高效氯氟氰菊酯EC 3000倍液>1.8%阿维菌素EC 4000倍液;药后3 d时,25 g/L高效氯氟氰菊酯EC3000倍液>1.8%阿维菌素EC 4000倍液>20%啶虫脒WP 10000倍液;药后15d时,20%啶虫脒WP 10000倍液>1.8%阿维菌素EC 4000倍液>25 g/L高效氯氟氰菊酯EC 3000倍液。旨在掌握防控柑橘潜叶蛾合适的药剂选择,以期为柑橘产业的健康发展提供科学依据和实用技术。Citrus leafminer,as one of the main pests of citrus,has been concerned about its harm degree and control difficulty.In this study,the indoor toxicity test and field efficacy trials of citrus leafminer population in Guilin area were conducted using leaf-dipping method.The results of indoor toxicity test showed that the LC_(50) values were ranked as follows:chloramidine>abamectin>cypermethrin>cyhalothrin.The results of field efficacy trials showed that:At 1d,10d and 20d after treatment,the control effect ranking was:20%acetamidine WP 10000 times liquid>25 g/L cyhalothrin EC 3000 times liquid>1.8%abamectin EC 4000 times liquid;3 days after treatment,the control effect ranking was:25 g/L cyhalothrin EC 3000 times solution>1.8%abamectin EC 4000 times solution>20%acetamidine WP 10000 times solution;15d after treatment,the control effect ranking was:20%acetamidine WP 10000 times solution>1.8%abamectin EC 4000 times solution>25 g/L cyhalothrin EC 3000 times solution.The trials aimed to master the selection of appropriate pesticides for the prevention and control of citrus leafminer so as to provide scientific basis and practical technology for the healthy development of citrus industry.
