摘要
紫穗槐豆象为林业部二十种国内森林植物检疫对象之一,1978年9月在金华县首次发现危害,1年发生1～2代,成虫雌雄性比为1.14:1,有假死性和多次交尾习性,幼虫营隐蔽生活和滞育性。天敌有螽蟖、金小峰。带虫种子可用20g/m^3磷化铝熏蒸和60℃热水恒温浸泡10分钟或70℃热水变温浸泡处理10～20分钟。在成虫羽化盛期可用甲胺磷、氧化乐果800～1000倍液或菊乐合酯1000倍液防治,效果甚好。除加强对引进种子进行检疫外,还应做好林地虫源清除,在严重危害地区,清明前进行插条造林进行林分改造,都能收到较理想的效果。
Acanthoseelides pallidipennis is one of quarantine targets of 20 species of
domestic forest plants. On September 1978, harm was first happened at jinhua county, happening
1-2 generations in a year, female and male adult was in a ratio of 1.14 to 1, having habits
and characteristics of suspended animation, mating repeatedly, concealed living of Iarva camp
and sluggish fertility. Its natural enemies are katydid and plermalid. The seed with insect
can be fumigated with 20 g/m^3 aluminium phosphide and immersed in 60℃ hot-water for 10
min by constant femperature or in 70℃ hot-wafer for 10～20 min by poikilothermisn At flou-
rishing period of adult eclosion, control with methamidophos, oxidize rogor liquid of 800～
1000 times or fenvalerate dimethoate liquid of 1000 times,the result is good. Besides strength-
ening quarantine for introduced seeds, clearing away adult source of forest land,transplanting
a cutting for afforestation and stand transformation and they all achieve ideal results.
