管氏肿腿蜂(Scleroderma guani)(以下简称肿腿蜂)1973年在我省被发现。由于这种蜂具有很强的钻蛀和寄生能力,在防治天牛等钻蛀性害虫上取得了很好的防治效果,因此很快推广到全国15个省市。繁蜂的寄主是很多的,但优良的寄主却不多,其中以天牛等幼虫最为优良,但要取得天牛幼虫须伐木或截枝,既费工又费木材,因此使这种蜂的应用受到一定的限制。为此我们开展了利用大蓑蛾(Clania variegata)的雄性幼虫繁殖肿腿蜂的试验,到目前为止,已繁殖出肿腿蜂200多万头,成为目前繁蜂量较多的寄主之一。大蓑蛾是国内外分布较广的害虫之一,它数量多,集中易取,摘取后既可达到人工防治的目的,又可获得大量繁蜂的寄主。现把试验情况报告如下。
Scleroderma guani (hereinafter referred to as swollen leg bee) was found in our province in 1973. Because of this bee has a strong drilling and parasitic capacity, prevention and control of borers and other bore insects have made a very good control effect, it quickly spread to 15 provinces and cities nationwide. Many bee hosts are many, but not many excellent hosts, of which the best larvae such as celastrus, but to obtain day-long larvae need to cut or cut branches, both the cost of work and expense of wood, so that the bees Application is subject to certain restrictions. To this end, we carried out the trial of using the male larvae of Clania variegata to reproduce the swollen-legged bee. So far, more than 2 million swollen-legged bees have been bred so far and become one of the hosts with a large amount of breeders. Large moth is one of the most widely distributed pests at home and abroad, it is a large number of easy to take, easy to take, after removal can achieve the purpose of artificial control, but also access to a large number of bee host. The test report is as follows.
