白虫是紫胶虫的主要天敌,而白虫小茧蜂又是白虫的寄生天敌。消灭白虫对发展紫胶生产具有重要的意义。我场除采用种胶检疫、及时采收、剥种胶加工等机械防除外,还人工饲育了小茧蜂,进行胶林放蜂。现在林中的小茧蜂已形成了群落,基本上控制了白虫的危害,同时也节约了大量劳力。现将人工饲育小茧蜂和胶林放蜂技术简介如下:
White worms are the main natural enemies of the lac bug, while the white-worm larvae are white parasites predators. The elimination of white worms is of great importance to the development of shellac production. In addition to the field of plastic quarantine, timely harvesting, stripping plastic processing and other mechanical control, but also artificial breeding Calocatus bee, the plastic forest put bees. Now the forest callus has formed a community, basically control the harm of white worms, but also save a lot of labor. Artificial breeding of small calluses beetle and plastic forest bee technology is as follows:
