速生桉新造林地白蚁药剂防治试验

Field trials for controlling termites in instant Eucalyptus forests

为筛选出高效、低毒、低残毒、符合环保要求的白蚁防治药剂,从目前国际上开发的新型白蚁防治药剂中,选用5类有代表性的药剂及复配制剂进行速丰桉新造林地白蚁防治田间试验,结果表明:5%阿维菌素可湿性粉剂、50%福美双可湿性粉剂、2.5%溴氰菊酯乳油、40%毒死蜱乳油、22%甲维氟铃脲可湿性粉剂及复配药剂在林间防治效果均达70%以上。其中,生物制剂5%阿维菌素可湿性粉剂和复配药剂防治效果达85%以上,可以代替氯丹、灭蚁灵和毒死蜱在白蚁防治中使用。同时阿维菌素对环境友好,在林木白蚁防治中有较好的应用前景。

Results were as follows： it could be reached to 70% for termites controlling in instant Eucalyptus forests with 5% abamectin WP, 50% thiram WP, 2.5% deltamethrin, chlorpyrifos 40% EC, 22% WP emamectin hexaflumuron and compound pharmacy. Biological agents like 5% avermectin compound WP and the effect of chemical could reach to 85%, and it could replace chlordane, mirex in termite control and the use of chlorpyrifos. What＇s more, avermectin had no harm for human beings and beast, especially for environmental prevention, so it could be used in controlling and preventing instant Eucalyptus forests.
