云斑天牛在河北主要分布于太行山各县,危害核桃,使核桃木材丧失利用价值,产量大幅度下降,该虫以成虫及各龄幼虫越冬,其中2~3龄占56.6%。越冬成虫翌年4月中旬开始羽化,补充营养后分6~12次交尾产卵。产完最后一次卵继续取食38~54天死亡。6月中旬用50%杀螟松乳油或40%氧化乐果乳油涂抹产卵刻槽中的幼虫或8月中旬至9月下旬用磷化锌毒签插入云斑天牛侵入孔,对成、幼虫熏杀效果显著。秋冬或早春砍伐濒死、枯死木可以减少部分虫源。
The genus Bugs are mainly distributed in the counties of Taihang Mountains in Hebei Province, endangering the walnuts and depriving them of the value of the utilization of walnut wood. The yield of the pears is greatly decreased. The worms overwinter for adults and larvae of all ages, of which 56.6% are from 2 to 3 years old. Overwintering adults in mid-April next year began to emerge, supplemented nutrition 6 ~ 12 times after the end of oviposition. After the last egg production to continue feeding 38 to 54 days of death. Mid-June 50% fenitrothion EC or 40% omethoate smear spawning larvae or middle of August to late September with zinc phosphate poisoning tag into the clouds of Haemaphorus into the hole, into, Larvae smoked significant effect. Autumn or winter cut dying, dead wood can reduce some of the source.
