摘　　要：为明确50%呋虫胺WG等药剂对稻飞虱的防治效果,在溧阳、张家港、武进等地进行了田间药效试验。溧阳、张家港点试验结果表明:50%呋虫胺WG、60%吡蚜·噻嗪酮WP、25%吡蚜酮WP对稻飞虱均有较好防效,3种药剂的持效性相当。武进点试验结果表明,50%呋虫胺WG对褐飞虱的防治效果好于对白背飞虱和灰飞虱的防效。50%呋虫胺WG和60%吡蚜·噻嗪酮WP具有较好的推广价值,可在生产上与吡蚜酮交替使用。In order to definite the control effects of dinotefuran 50% WG on rice planthopper, the field trials were carried out in Liyang, Wujin and Zhangjiagang. The results showed that dinotefuran 50% WG, pymetrozine ＋ buprofezin 60% WP and pymetrozine 25% WP could control rice planthopper effectively. The control effects were all above 80% on the 21 th day after spraying, and the persistence efficacies of the three pesticides were well-matched. Compared with Laodelphax striatellus and Sogatella furcifera, Dinotefuran 50% WG performed better control effect on Nilaparvata lugens.Dinotefuran 50% WG, pymetrozine ＋ buprofezin 60% WP could replace pymetrozine to control rice planthopper, were worth promoting.
