栗实蛾生物学特性及防治技术研究

Biological Characteristics of Laspeyresia splendana(Hubner) and Techniques to Control

栗实蛾是板栗的重要害虫。通过对该虫生物学特征及防治技术研究表明,该虫在陕西镇安1年发生1代,以老熟幼虫作黑红色扁椭圆形茧在栗林杂草、落叶下越冬,次年7月中旬开始化蛹,8～9月成虫羽化,9～10月幼虫大量蛀食坚果。采取林业防治,药剂防治等综合防治技术,防治效果显著。

Laspeyresia splendana（Hubner） is one of the severest pest attacking chestnut.The research on its biological characteristics as well as control techniques revealed that Laspeyresia splendana （Hubner） occurs in one generation per year.Cocoon of it stays over winter under the litter or weeds,and pupates in July and adult emerges in August and September of next year.During the month of October,larvae begins to feed on nuts.Management measures integrated with other pesticides would achieve better effect.
