过去,由于人们在棉铃虫防治上过分依赖化学农药,而产生了棉铃虫抗药性提高、农业生态平衡失调及环境污染等一系列问题,控制棉铃虫为害已成为世界植保业共同面临的难题。因此,寻求控制棉铃虫为害的新途径已迫在眉睫了。 近年来,以色列沃尔坎尼农业研究中心的Ⅰ·格莱兹尔和A·纳温两位科学家,利用斯氏线虫属的褐夜蛾新线虫的All株系和Pye株系及异杆线虫属的Hp88株系,在室内条件下,进行了防治棉铃虫试验,并取得了成功。这类昆虫寄生线虫的杀虫机理,是通过棉铃虫取食而进入棉铃虫体内,在寄主
In the past, due to over-reliance on chemical pesticides in the control of cotton bollworm, a series of problems such as increased resistance of cotton bollworm, imbalance of agricultural ecological balance and environmental pollution have come into being, and controlling the harm of cotton bollworm has become a common problem faced by the world’s plant protection industry. Therefore, the search for a new way to control the damage of cotton bollworms is imminent. In recent years, two researchers, I. Glezel and A. Nawen, of the Center for Agricultural Research in Volcani, Israel, used the All strains of Neospora and the Pye strain of the Helminthworm spp. Hp88 strain belongs to the genus Helicoverpa armigera, under the indoor conditions, the control bollworm test, and achieved success. The insecticidal mechanism of such insect parasitic nematodes, bollworm feeding through the body into the bollworm, the host
