为了筛选防治柑桔木虱成虫的有效药剂,试验采用一种新的方法,即将木虱饲养在九里香上,并用40目纱网套袋封口,然后进行9种农药防治柑桔木虱成虫药效试验。结果表明,48%毒死蜱EC 480mg/L、10%吡虫啉WP100mg/L、25%吡虫啉WP 250mg/L、20%甲氰菊酯EC 200mg/L、20%哒虱威EC 200mg/L、20%丁硫克百威EC 200mg/L、2.5%三氟氯氰菊酯EC 25mg/L、药后24h对柑桔木虱成虫的防治效果达97.1%～100.0%,生产上可单独使用;而采用20%异丙威EC+25%吡虫啉WP 450mg/L药后24h对柑桔木虱成虫的防治效果比单独使用的效果好,防效达到100.0%,表明杀虫剂合理混用可提高对柑桔木虱成虫的防治效果。
In order to screen effective agents for controlling adults of Citrus psylla, a new method was adopted, in which the lice were kept in Jiulixiang and sealed with a 40-mesh gauze bagging, followed by nine kinds of pesticides to control Citrus psylla adult medicine Effect test.
