不同黄色粘虫板对烟蚜及蚜传病毒病的防治效果

摘要

为筛选对烟蚜防治效果较好的黄色粘虫板(简称黄板)应用于生产,进行英格尔公司黄板和河南佳多公司黄板对烟蚜田间防控的对比试验,以常规化学防治(喷10％吡虫啉3 000倍液)为对照.结果表明:2种黄板均显著降低烟蚜虫口数,使用20 d后分别比对照降77.9％和85.3％;使用黄板虫口减退率明显高于对照,差异达极显著水平;2种黄板田间蚜传病毒病病情指数分别比对照下降57.1％和85.7％,发病率下降62.5％和81.25％.河南佳多公司的黄板防治效果显著优于英格尔公司的黄板.%The comparative trial of two kinds of yellow sticky boards produced by Engle and Jiaduo Company respectively against M.percicae was conducted in tobacco field by taking conventional chemical control (10％ I 300 Imidacloprid) as CK to select the yellow sticky board with better control effect against M.percicae for tobacco production.Results:Two kinds of yellow sticky boards both reduce population number of M.percicae significantly and the population number of M.percicae of two kinds of yellow sticky boards produced by Engle and Jiaduo Company decreases by 77.9％ and 85.3％ after 20 d compared with CK respectively.The dropping rate of M.percicae of two kinds of yellow sticky boards is higher than CK very significantly.The aphid-borne virus disease index and disease rate of two kinds of yellow sticky boards produced by Engle and Jiaduo Company decreases by 57.1％ and 85,7％,and 62.5％ and 81.25％ compared with CK separately.The control effect of the yellow sticky board produced by Jiaduo Company is better than the yellow sticky board produced by Engle Company significantly.
