摘要
本文报道了对大蜡螟形态及生活习性方面的观察和防治试验的结果,初步筛选出454和UV-17两种苏芸金杆菌制剂为有效药剂,毒力测定结果表明,死亡率高达94.0%和87.3%;在喷脾防治中,其防治效果分别为62.6%和71.3%以上,施药方法,以巢蜡渣拌粉为佳,使用浓度,454为0.15g粉/100g蜡渣,UV-17为0.10g粉/100g蜡渣。
Greater wax moths (Galleria mellonella L.) belong to fami-ly pyralidae, subfamily galleriinae and they are important natural enemies ofChina bees(Apiscerana Fab.). The paper reports the morphology and biology ofthe Galleria mellonella L., and corrects some errrrs reported by former resear-chers on the subject. In addition, it sums up the results of the screen test on 4Bacillus thuringiensis. According to laboratry tests, the martalitie of powder 454and UV-17 treatments for 1~3 instar larvae are 94% and 87.3% respectively. And in hive tests, powder 454 and UV-17 kill 71.3% and 62.6% of larvae res-pectively and bring no harmful effect on the bees and broods.
