黄檀丑舟蛾生物学特性及防治的研究

Studies on biology and control of Hyperaeschra pallida Butler

黄檀丑舟蛾是南岭黄檀的重要食叶害虫，该虫在福建南平一年发生６代，以蛹在疏松土壤中越冬，翌年５月初成虫开始羽化。雌虫产卵于嫩叶上，成块。每雌产卵８２－３０６粒。幼虫５龄，各代幼虫的危害盛期：第一代５月下旬至６旬上旬，第二代６月下旬，第三代７月下旬，第四代８月中旬，第五代９月下旬，第六代１１月上旬至中旬。试验表明，２０％杀灭菊酯４０００倍液或８０％敌敌畏２０００倍液对幼虫均有良好的毒杀效果。

The notodontid moth Hyperaeschra pallida Butler is a serous pest of Deabergia balansae Prain in Fuian Province. The studies during 1987 to 1996 showed that the pest has six generations each year and overwinters with pupa in the soil. The adult moth begins to appear in early May next year. Each female can lay 82 to 306 eggs. The larva generally has five instars. The serious harm period of this pest are late May to early June, late June, late July, mid August , late September and early November to mid November, respectively. Spraying with 80% dichlorvos (1:2000) or 20% fenvalerate (1:4000) is an effective control measure over the larvae of this pest.
