| 摘 要： | 通过野外观察及室内饲养相结合的方法，进行桑褐刺蛾的生物学习性及防治研究。研究发现桑褐刺蛾在浙江莫干山1a发生2代，以老熟幼虫在树下土壤内做茧越冬，翌年5月初化蛹，成虫于5月末始见羽化，6月中旬始见初孵幼虫。幼虫有8个龄期。以树干柱枝打孔注射农药方法，对桑褐制蛾进行防治研究。在幼虫出现前2周在悬铃木主枝上按1cm胸径打孔注射2mL50％甲胺磷乳油、40％氧化乐果乳油和50％久效磷水剂，平均校正死亡率分别为85．8％，84．8％和82．6％，图1表4参8

| Abstract: | The biological characteristics of Setora postornata was systematically described by means of observation in nature and laboratory．The research shows that Setora postornata occurs two generations per year at Mt．Mogan in Zhejiang Provice and overwinters with elder larva in the soil．Its pupae hatch at the beginning of May，and adults appear at the end of May．The method of injection pesticides in bored holes on trunks was firstly applied to controlling Setora postornata on Platanus acerifolia，P． orientalis，and P． occidentalis．Omethoate 40EC，methamidophos 50EC and monocrotophos 50 aqueous solution were injected into the main brances of three Platanus species before larva，appearing two weeks，and the average corrected mortality of larva could reach 84.8%，82.6% and 85.5%． |
