摘要
20 0 2～ 2 0 0 3年 ,采用 10 %吡虫啉、70 %艾美乐、2 1%毕达、2 5 %阿克泰、5 0 %库龙、2 5 %稻虱净、2 5 %功夫、90 %万灵、4 0 %速扑杀等 9种化学药剂 ,对橄榄星室木虱进行防治试验。根据防治效果、成本、化学药剂理化性质以及作物安全性 ,筛选出吡虫啉 1.0 0 g/L液、毕达 1.0 0 g/L液 2种处理为最佳 ,防治效果分别在 98.5 4% ,92 .35 %以上 ,药剂成本 2 .0～ 3.0元 / (6 6 7m2 ·次 ) ,可在生产上进行大面积推广应用。为避免害虫产生抗药性 ,可有选择地采用功夫 0 .5 0 g/L液、万灵 0 .2 5 g/L液、阿克泰 +功夫 (0 .12 5 + 0 2 5 0 )g/L液、艾美乐 0 .2 5 g/L液、阿克泰 0 .5 0 g/L液等处理进行交替使用。库龙、速扑杀、稻虱净不宜使用。
kinds of pesticide was used to control Pseudophacopteron canarium Yang et Li by 3 concentration level in Canarium album nusery and forest during 2002 and 2003. The pesticide include 10% Imidacloprid, 70% Confidor, 21% Acetamiprid, 25% Actara, 50% Curacron, 25% Buprofezin, 2.5% Cyhalothrin, 90% Methomgl and 40% Methidathion, their control effect, cost, character and plant security are analyzed in the paper. Imidacloprid (1.00 g/L) and Acetamiprid (1.00 g/L) are regarded to be the most effective and economic, their control effect are 98.54% and 92.35%. Their cost was 2.0～3.0 yuan every 667 m2 per time. To prevent the pests from having resistance, Cyhalothrin (0.50 g/L), Methomgl (0.25 g/L), Actara+Cyhalothrin (0.125+0.25) g/L, Confidor (0.25 g/L) and Actara (0.50 g/L) can be used alternatively. And Curacron, Methidathion and Buprofezin are not adopted for other reasons.;
