摘要
为了筛选出最适合防治茶梢蛾的农药,选用6种生物农药和1种化学农药对茶梢蛾幼虫的毒杀力进行了室内测定,并用筛选出的20%乐果乳油、2%阿维.苏可湿性粉剂和3%阿维.氟铃脲乳油这3种毒力较强的农药进行了林间幼虫防治试验。结果表明:使用阿维.苏、阿维.氟铃脲和乐果的2 000倍液进行喷雾防治的效果较为理想,可达到74%～84%的杀虫效果;而用阿维.苏、阿维.氟铃脲和乐果以注干施药法进行防治的杀虫效果并不明显。
In order to select the most suitable pesticide of controling Parametrites theae, toxicity of six kinds of biological pesticides and one kind of chemical pesticide to P theae larvae were determined indoor, and larvae control test in forest was carried on by the toxicities with stronger toxicity, including 20% dimethoate, 2% abamectin-bacillus thuringiensis and 3% abamectin-hexaflumuron. The results showed that the three biological pesticides diluted with water by 2 000 times to control larvae by spraying, got a good killing effect of 74%-84%. But the three pesticides applied by trunk injecting method had no obvious control effect.
