摘　　要：为了有效保护林木病虫害防治区周边人、畜安全和农产品卫生质量安全,在祁连山东端地区观察了柳厚壁叶蜂生活史和形态特征,调查了其为害程度,并开展了4种植物源药剂防治筛选试验。结果表明:在祁连山东端地区柳厚壁叶蜂一年发生1代,发生率和虫口密度受调查地海拔影响,中部川区发生率和虫口密度最高,南部山区最低,北部旱区居中。4月下旬成虫羽化盛期喷洒不同植物源药剂后,均降低了发生率和虫口密度,其中喷洒3.2%苦参碱乳油2000倍液的防治效果最佳,发生率和虫口密度均为0,建议在祁连山东端地区柳厚壁叶蜂防治中优先选用。In order to protect safety of people and animals and produce beside disease and insect pest control area,the life history and morphological characteristics of Pontania caprea L were observed in Qilian Mountain eastern end,the harm degree was investigated,and the screening test of four plant source pesticide was did.The result showed that the Pontania caprea L occurred one generation in a year,the incidence and pest density were affected by altitude of investigation areas,the incidence and pest density of middle valley were the highest in all investigation areas,the southern mountains are the lowest,and the northern dry area was in the middle.After the different plant source pesticides were sprayed in late April adult emergence peak period,the incidence and pest density were decreased separately,the control effect of 3.2%matrine oil 2000 times,whose incidence and pest density were zero separately,which should be used to control Pontania caprea L firstly in Qilian Mountain eastern end.
