近几年来,从东京都开始,埼玉县、神奈川县的独活栽培地区,刺楸天牛〔Dihammusluxuriosus (Bates)〕大量发生,为害甚重。本种的生活史尚不大清楚,故1977年以来,笔者们对其发生生态进行了研究(新井1979),搞清了一部份生活史,并确定了防治对策(新井1980)。这些成果的取得,都是由于确定了用人工饲料大量饲养刺楸天牛,从而有充足的虫源可供各实验应用的结果。关于天牛幼虫的人工饲养,迄今已有所研究。可是,简易地大量饲养天牛幼虫的方法还没有成功。大量饲养,不仅包括幼虫饲养,还包括成虫饲养、采卵等,有必要使饲养的全过程系统
In recent years, in Tokyo alone, the live-cultivated areas of Saitama Prefecture and Kanagawa Prefecture, Dihammus luxuriosus (Bates), have occurred in large numbers and are particularly devastating. The life history of this species is still unclear. Therefore, since 1977, the authors studied the ecology (Arak 1979), clarified part of their life history, and identified prevention and control measures (Arai 1980). The achievement of these results was due to the fact that a large amount of artificial feed was used to feed Catalpa ferociousus so that sufficient sources of insect were available for experimental use. Artificial breeding of day larvae has so far been studied. However, the simple and easy method of feeding large numbers of larvae of celastris has not been successful. A large number of rearing, including not only larvae feeding, but also adult feeding, oaws, etc., it is necessary to keep the whole process of feeding system
