【摘要】 调查表明,樟巢螟(Orthaga achatinaBulter)和樟叶蜂(Moricella rufonotaRohwer)是上海地区危害香樟生长和影响景观效果的2大重要食叶害虫。樟巢螟在上海地区年发生2~3代,6月上旬~7月下旬、8月上旬~9月下旬分别为一代、二代幼虫发生危害盛期,10月份发生少量第三代幼虫危害。樟叶蜂一般年发生2代,4月中下旬~5月上旬、6月分别为一代、二代幼虫发生危害盛期。通过试验,印楝素、杀虫安、抑太保、毒丝本、甲胺基阿维菌素和安打等高效低毒农药对1~2龄樟巢螟或樟叶蜂有优良的防治效果。更多还原

【Abstract】 The investigation showed that O.achatina and M.rufonota were two major defoliators influencing camphor tree growth and landscaping in Shanghai area.O.achatina occurred for 2～3 generations a year.The peak periods of damage by O.achatina larvae were respectively from the first 10 days of June to the last 10 days of July and from the first 10 days of Aug.to the last 10 days of Sept.,and in Oct.some damage by the larvae occurred.M.rufonota generally occurred for two generations a year and the peak periods of damage by M.rufonota larvae were from the middle or last 10 days of April to the first 10 days of May and in June.The control experiments showed that such low-toxic pesticides as toosedarin EC,profurite-aminium WP,chlorfluazuron EC,chlorpyrfos EC,metlylamineavermectin EC and indoxacarb SC had a good control efficiency on 1～2 instar O.achatina and M.rufonota.更多还原
