摘要
采用虫道注射方法,研究了吡虫啉和阿维菌素对桉蝙蝠蛾幼虫的防治效果。结果表明,两种杀虫剂对桉蝙蝠蛾幼虫平均虫口密度的防治效果为100%。吡虫啉8个月的持续防治效果稍高于阿维菌素,虫害防治效果达到70.4%,而阿维菌素为69.3%;两种药剂对桉蝙蝠蛾有较强和持续的抑制作用。吡虫啉和阿维菌素每孔注射适宜用药量为5ml(1:200)稀释液。
The tunnel injection experiment was made with different dosage of 10%Imidacloprid and 1.8%Avermectin B1 against Phassus sp.larvae.The result showed the control effect reached 100%respectively 3 month after the injection.The better dosage was 5 ml dilute liquid(1:200) per hole.Tunnel injection had certain control effect on larvae.
