摘要
利用14%吡虫啉.敌敌畏注干液剂、4.5%吡虫啉注干液剂、2%阿维菌素注干液剂和30%敌畏.氧乐注干液剂等对危害椰树的椰心叶甲进行了树干注射防治试验。结果表明14%吡虫啉.敌敌畏注干液剂、4.5%吡虫啉注干液剂和30%敌畏.氧乐注干液剂,对椰心叶甲有较好的防治效果。其中14%吡虫啉.敌敌畏注干液剂防效最好,注药量0.7 mL/cm,30 d防效达95.10%。2%阿维菌素注干液剂防效差,30 d防效仅为32.84%。
The field bioassay of 4 trunk injection insecticides （14 % Imidacloprid ＋ DDVP, 4.5 % Imidacloprid, 2 % Abamectin and 30 % DDVP ＋ omethoate） was conducted against Brontispa longissima. The results showed that 14 % Imidacloprid ＋ DDVP, 4.5 % Imidacloprid and 30 % DDVP ＋ omethoate were efficient, and 14 % Imidacloprid ＋ DDVP exhibits high efficiency. The control effect reached 95.10 % 30 days after the injection at the dose of 0.7 mL/cm trunk ground diameter.
