蓖麻夜蛾Achaea melicerta(Drury)又名飞扬阿夜蛾,分布于广东、广西、云南、台湾等地,是为害蓖麻的一种大害虫,据文献记载,河北地区不常发生。但据1963年8月间观察,幼虫在河北中部地区为害蓖麻很严重,咬食叶片呈花叶状,甚至只留下粗大叶脉,减产很大。1964年8月间又发现此虫为害蓖麻。因此我们进行了生活史观察和防治试验,现将结果作一初步整理,以供参考。 Achaea melicerta (Drury), also known as Flying Spider Moth, distributed in Guangdong, Guangxi, Yunnan, Taiwan and other places, is a large pest damage castor, according to the literature, rare in Hebei. However, according to the observation in August 1963, larvae were severely damaged in the central part of Hebei Province, and the bites of the leaves were mosaic-like, leaving only the large veins, resulting in a large reduction in production. In August 1964, it was found that the pest was castor. Therefore, we conducted a life history observation and prevention and control test. We will now make a preliminary review of the results for reference.
