摘　　要：旋目夜蛾是黑荆树的一种新害虫，在福建南平一年发生３代，以蛹越冬，翌年４月下旬开始羽化，卵期６～１８天；幼虫共６龄，幼虫期２３～４７天；蛹期８～１３天，但越冬代蛹１９４～２２８天．已知天敌有夜蛾瘦姬蜂、广大腿小蜂和家蚕追寄蝇．试验表明，溴氰菊脂、氰戍菊脂和敌百虫等农药对幼虫均有良好防治效果．The wavy huge-comma moth Speriradonia retorta Linnaeus is a new pest of Acacia mearnsii in Fujian Province. This paper reports the results of our studies made from 1986 to 1990 on the bionomics control of this pest. It has three generations a year and overwinters as pupa in Nanping,Fujian Province. Adult moth begin to appear in late April next year. The egg stage lasts 6-18 days. The larvae generally have six instars and last 23-47 days. The pupal stage lasts 8-13 days and the overwintering pupa last 194-228 days.Ophion luteus (L.), Brachymeria obscurata(Walker) and Exorista sorbillans Wiedemann are major natural enemy. The effective measures to control the larvae are spraying of Deltamthrin,Pydrin or Dipterex.
