摘要(Abstract)：
近年来,西双版纳白木香人工林大面积的爆发了食叶害虫黄野螟,对白木香人工林造成严重危害。为探索防治该虫的有效办法,在西双版纳普文镇4 a生白木香人工林里,选择5种杀虫剂进行林间防治试验。结果表明:5种杀虫剂对黄野螟的幼虫均有一定的防效,以甲维·茚虫威和甲氨基阿维菌素苯甲酸盐的杀虫效果较好,3种浓度药后1 d校正死亡率均达到100%,其次是氯氰·毒死蜱,药后2 d达到100%,2.5%高效氯氟氰菊酯在药后4 d也达到100%,而生物农药5%的苦参碱在药后1 d防效表现最弱,但药后4 d均能达到75%以上。
In recent years,a leaf-eating pest,Heortia vitessoides,was found in a large area in the plantation of Aquilaria sinensis in Xishuangbanna,which caused serious damage to the plantation.In order to explore an effective way to control this pest,five insecticides were selected to carry out the control experiment in the 4-year-old A. sinensis plantation in Puwen Town,Xishuangbanna.The results showed that all the five insecticides had certain control effects on the larvae of Heortia vitessoides,and the insecticidal efficacy of methyl-indenocarb and emamectin benzoate was better.The corrected mortality rate of the three pesticides reached 100% one day after treatment,followed by chlorpyrifos and cypermethrin reaching 100% two days after treatment and 2.5% cyhalothrin reaching 100% 4 days after treatment., effect of 5%matrine was the weakest one day after treatment,but mortality rate could reach 75% four day after treatment.
