我国科学家从生物控制的角度出发,系统地调查了美国白蛾的寄生性天敌,从其卵、幼虫和蛹中饲养出了20多种天敌昆虫,使为非作歹20多年的森林害虫-美国白蛾,正受到名为白蛾周氏啮小蜂的猛烈攻击。相继在大连、烟台、秦皇岛、天津等地土崩瓦解。战胜敌手的小蜂身长只有1毫米,却神奇非凡,将产卵器刺入美国白蛾蛹内,平均产下270多粒卵,在白蛾蛹内发育成长,最后消灭了敌人而壮大了自己,由此而成为“森林小卫士”。这项“以利用白蛾周氏啮小蜂为主
From the perspective of biological control, Chinese scientists systematically investigated the parasitic natural enemies of American white moth, and raised more than 20 kinds of natural enemy insects from their eggs, larvae and pupae to make forest pests such as American white moth, Is being attacked by a small bee called the White Moth Chow’s. One after another in Dalian, Yantai, Qinhuangdao, Tianjin and other places collapsed. The bee-bee over the rival is only 1 millimeter in length, but miraculously, the ovipositor spurs into the American white moth pupae, producing an average of more than 270 eggs and growing within the white moth pupae, eventually wiping out the enemy and strengthening himself , Thus becoming “forest defender.” The "use of white moths Zhou Zai Xiaobian based
