摘要
试验结果表明，当板栗进入结果期后，少量金龟子的存在(危害程度 30% 以下)对板栗当年产量和单果重并不产生显著影响，一般不需对其进行药物防治；当金龟子危害程度超过 30% 时，可采取相应的综合有效的防治方法；而建园当年和幼龄期板栗，金龟子危害会严重影响板栗早期丰产树冠的形成，应及时采取适宜的防治措施。
：Tests showed that ,after Castanea mollissima enters into mature period,a small amount of scarab had no significant effects on its yield and weight of single fruit; When damage caused by scarab exceeds 30%,comprenhensive control measures should be applied; At juvenile stage of Castanea mollissima, scarab can seriously affect formation of tree crown. Thus,control measures should be applied in time.
