虫螨腈、高效氟氯氰菊酯等防治柑橘灰象甲、小绿象甲药效试验

摘要

For controlling citrus small pale curculio （Sympiezomia citri） and citrus smaU pink green curculio （Platymycteropsis mandarus）, the pesticides were screened in laboratory and field. The result showed that the best effective mixed pesticides were 12.5 % Chlorfenapyr plus beta-cyhalothrin EC and 12.5 % Chlorfenapyr plus beta- cyfluthrin EC. The recommended liquid time was from 2 O00-fold to 2 500-fold.%对虫螨腈与氯氟氰菊酯进行防治柑橘灰象甲、小粉绿象甲的药效试验。结果表明，12．5％虫螨腈＋氯氟氰菊酯EC、12．5％虫螨腈＋高效氟氯氰菊酯EC可以用来防治柑橘灰象甲和小绿象甲，推荐使用倍液数为2000-2500倍液。
