摘要： 控制柑桔木虱是柑桔黄龙病综合防治最重要的技术措施。柑桔木虱成虫的高效传病性、近距离扩散性、终生带毒性和快速传病性，决定了用来防治柑桔木虱成虫的农药要求速效性好、防效高（药后24h的防效＞95%）。由于受到试验地虫源和试验条件的限制，柑桔木虱的有效防治药剂筛选严重滞后。2006—2007年我们做了15种农药的田间药效试验，结果表明：哒虱威EC 200mg(a.i)/L、丁硫克百威EC 400mg(a.i)/L对柑桔木虱成虫药后24h的防效＞95％；防效在94.9%~90％的有异丙威200mg(a.i)/L、133mg(a.i)/L、丁硫克百威EC 250mg(a.i)/L；噻嗪酮250mg(a.i)/L的防效只有30.8%；防效低于30％的药剂有灭多威200mg(a.i)/L、鱼藤酮150mg(a.i)/L、机油乳剂9500mg(a.i)/L、阿维菌素20mg(a.i)/L和石硫合剂1波美度。机油乳剂与哒虱威混用无增效作用。

Abstract: Control of Asian citrus psylla is the most important technical component of an integrated control program for huanglongbing.Adult psyllid control provided by pesticides must be >95% after 24h sprayed.15 pesticides was tested in field experiments. The results show that adult psyllid control provided by imidacloprid plus isoprocarb 200 mg(a.i)/L and carbosulfan 400mg(a.i)/L was >95%, the control of isoprocarb 200mg(a.i)/L and carbosulfan 250mg(a.i)/L was 94.9% to 90%, while buprofezin only gave 30.8%, and methomyl 200 mg(a.i)/L, rotenone 150 mg(a.i)/L, petroleum oil 9500 mg(a.i)/L, abamectin 20 mg(a.i)/L, calcium polysufide 1BE each provided <30% control, control was not enhanced when imidacloprid plus isoprocarb was mixed with petroleum oil.
