摘　　要：选用19种杀虫剂,以硅藻土及黄绵土作为农药载体,开展了藜麦(Chenopodium quinoa)甜菜筒喙象(Lixus subtilis Boheman)的室内防治试验。结果表明,以黄绵土或硅藻土为载体时,40%毒死蜱乳油和40%辛硫磷乳油都表现出了较高的速效性和持效性,7 d后防治效果均达100%,推荐生产使用。以硅藻土为载体时,可显著提高5%啶虫脒乳油、3.2%高氯·甲维盐微乳剂、5%甲氨基阿维菌素苯甲酸盐悬浮剂和20%呋虫胺可溶粒剂的防治效果,药后7 d防治效果分别为100.0%、100.0%、73.3%和95.8%,可有效防治藜麦甜菜筒喙象,推荐在生产中采用杀虫剂与硅藻土混合施用的方式施药。Using diatomaceous earth and yellow soil as pesticide carriers,19 insecticides were used to control Lixus subtilis Boheman of Chenopodium quinoa in laboratory.The results showed that 40%chlorpyrifos EC and 40%phoxim EC showed the quick-acting prop⁃erty and sustained performance,and the control effects reached 100%after 7 days,which was recommended for production.Using di⁃atomite as the carrier,the control effects of 5%acetamiprid EC,3.2%beta-cypermethrin·emamectin benzoate ME,5%emamectin benzoate SC and 20%dinotefuran soluble granule were significantly improved,and the control effects were 100.0%,100.0%,73.3%and 95.8%,respectively,after 7 days of administration,which could effectively control Lixus subtilis Boheman of Chenopodium qui⁃noa,and it was recommended to use the mixed application of insecticide and diatomaceous earth in production.
