黄枝子灰蝶(Deudorix eryx L.)是药材黄枝子的主要害虫。作者对该虫的形态特征和生物学特性进行了室内外的观察。室内饲养,在温度29.54±3.35℃条件下,完成一个世代需25.28±1.94天;对幼虫进行颜色标记,观察脱皮次数,确认幼虫共经四龄,和以前的报道有所不同;不同龄期幼虫特征有异。自然条件下:一年发生七代,全年以第一、二代发生量大,为害严重。幼虫钻蛀为害花、果,一头幼虫为害3～5个花、果,以3～4龄虫食量大,为害最甚,造成落花落果。掌握黄枝子灰蝶的生物学特性,对于防治具有实际的意义。
Deworix eryx L. is the main pest of medicinal herbs. The author observed the morphological and biological characteristics of the insect both indoors and outdoors. Indoor breeding, at a temperature of 29.54 ± 3.35 °C, to complete a generation requires 25.28 ± 1.94 days; larvae were color-labeled, observe the number of peeling, to confirm the larvae after four instar, and previous reports are different; different age larvae Features vary. Under natural conditions: Seven generations occur in one year, and the first and second generations occur in large quantities throughout the year, causing serious damage. The larvae bore fruit and fruit, and one larvae damages 3 to 5 flowers and fruit. The larvae of 3 to 4 instars have a large amount of food, causing the most damage and causing fruit drop and fruit drop. It is of practical significance to control the biological characteristics of the yellow butterfly butterfly.
