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。
The results showed that when the chestnut into the fruiting period, the presence of a small amount of chafers (degree of harm below 30%) on chestnut yield and weight per unit fruit does not have a significant impact, generally do not need its drug control; when the chafer damage more than 30 %, The corresponding comprehensive and effective methods of prevention and treatment can be adopted. However, the damage of the chestnut and the scarab in the current year and the early years of the park can seriously affect the crown formation of the early chestnut and should take appropriate control measures in time.
