摘要： 为了明确玉米田褐足角胸叶甲的发生规律和生活习性,采用田间系统调查与观察的方法,防治技术研究用喷雾和撒颗粒剂两种方法对不同药剂进行筛选试验。结果表明,褐足角胸叶甲在河北省一年发生一代,成虫发生始期在6月底7月初,发生高峰期为7月6-26日,末期为8月10日。成虫有短暂的假死性,白天阳光照射比较强时,喜欢躲藏在玉米心叶内为害,早晚在叶片上为害的习性。用48%毒死蜱乳油、4.5%高效氯氰菊酯乳油、25%氯.辛乳油、2.5%功夫菊脂乳油、40%辛硫磷乳油、2.5%溴氰菊酯乳油成虫期喷雾防治效果均在87.08%以上;撒5%毒死蜱颗粒剂防效达96.56%,也具有较好的防治效果。

Abstract: Occurrence Patterns and living habits of Basilepta fulvipes was investigated and observed in Hebei province.Screening of pesticids against Basilepta fulvipes was conducted by spraying and sprinkling in the field.There is one generation a year in Hebei.The adult appears from late of June to early of August,the peak period of adult is from 6th to 26th of July.The adult has temporary feign death and feed leaves of maize in the morning and evening.when the sunlight is stronger,the adult hide to feed in heart leaf.The control efficacy of 48% Chlorpyrifos EC,4.5% beta-cypermethrin EC,25% beta-cypermethrin·phoxim EC,2.5% cyhalothrin EC,40% phoxim EC,2.5% Deltamethrin EC were over 87.08% by spraying
