二化螟是水稻的三大害虫之一,每年都要投入大量的农药和人力进行防治。由于长期大量使用化学农药,必然会导致害虫抗药性的产生,为研究二化螟对杀虫剂的敏感性和抗药性,需通过室内饲养,获得大量生长一致的幼虫进行测定。二化螟是一种较难饲养的害虫,作者通过2年的田间采集和室内饲养,把有关经验教训总结如下。1 虫源采集1.1 成虫采集成虫采集适宜越冬代虫源采集。因越冬代成虫羽化时正处于早稻育秧后期,此时秧田面积小,成虫集中在秧田栖息、产卵,可用
Chilo suppressalis is one of the three major pests of rice. Every year, a large amount of pesticides and manpower should be put into control. Due to the long-term use of chemical pesticides in large quantities, it will inevitably lead to the emergence of pest resistance. In order to study the sensitivity and resistance of Chilo suppressalis to insecticides, indoor larvae should be used to obtain large numbers of uniformly grown larvae. Chilo suppressalis is a pest that is more difficult to keep. The author summed up the relevant experiences and lessons through two years of field collection and indoor rearing. 1 insect collection 1.1 adult acquisition of adult collected collected overwintering on behalf of the adult source. Due to the overwintering generation of adult feathers is in the late rice seedling, when the area of small seedlings, adults concentrated in the seedling habitat, spawning, available
