竹螟林间防治技术研究

Study on control techniques against Algedonia coclesalis and Crocidophora evenoralis in the forest

通过不同药剂不同施药方法对竹螟进行林间防治,得出用40%氧化乐果乳油或5%锐劲特悬浮剂或8%绿色威雷微胶囊水悬剂喷雾或向竹杆基部注入40%氧化乐果乳油或40%久效磷可溶性浓剂,防治效果均达70%以上。在毛竹根区埋施3%呋喃丹颗粒剂防治效果最高,但防治成本较高。利用白僵菌喷雾、打粉炮对竹螟有一定的防治效果,能增加林间带菌量达到可持续控制的目的。

Methodology and drugs use to prevent and control Algedonia coclesalis and Crocidophora evenoralis. The control effect may reach 70% and more. Controls include spraying with 40% omethoate emulsifiable concentrate of 5% Regent flowable formulation or 8% cypernethria slow release formulation or injecting in a tree-hole with 40% omethoate emulsifiable concentrate or 40% monocrotophos solution. The control effect may be highest incorporating carbofuran granules into soil, but the cost is relatively high. Beauveria bassiana has some control effect, it can increase the germs amount and achieves the sustainable purpose to control the pest.
