研究结果表明 ,在生草制果园金纹细蛾发生危害程度较重 ,虫情指数较清耕园高 39.85 %～ 4 4 .87%。其猖獗危害原因是生草制果园无法进行冬季清园 ,且生草制果园由于植被覆盖 ,对园内土壤具有明显的保湿、保温效果 ,为金纹细蛾安全越冬提供了一个良好场所 ,导致虫口数量增多。药剂防治应在一代成虫盛期进行 ,防效较好的药剂有 2 5 %灭蛾净乳油 1 0 0 0倍 ,2 5 %灭幼脲 3号 2 0 0 0倍 ;并提出应大力推广性诱防治和保护利用天敌等综合防治对策 The results show that in the grass orchard gold moth damage occurs more serious insect index higher than the clear tillage 39.85% ~ 44.78%. The reason of its rampant harm is that the grass orchard can not carry out the winter clearing, and the grass orchard has obvious moisturizing and heat preservation effects on the soil in the park due to vegetation cover, which provides a good place for the safety of the gold moth. Insect population increased. Prevention and treatment of pesticides should be carried out in the peak of a generation of adult insects, and the best control effect is 25% of the neem EC and 100% of the 25% of the MDEA No.3; Lure prevention and protection and use of natural enemies and other integrated control measures
