| 摘 要： | 在室内用辛硫磷对采自江苏东台的棉铃虫Helicoverpa armigera连续筛选了12代，平均成活率为37.6%，抗性上升了4.9倍。据Tabashnik介绍的方法，估计了抗性现实遗传力为0.0865。并预报了棉铃虫对辛硫磷的抗性发展速率。还对抗性风险评估、影响抗性发展速率的因素及抗性治理进行了讨论。

| Abstract: | Continuously selected with phoxim for 12 generations at the average survival percentage of 37 6%, the strain of Helicoverpa armigera, collected from Dongtai County, Jiangsu Province, had a 4 9-fold increase in resistance to phoxim. Based on the method described by Tabashnik(1992), the realized heritability (h 2) of resistance to phoxim in H. armigera was estimated to be 0 0865 The rate of resistance development in the cotton bollworm was predicted based on the estimation of the realized heritability (h 2). Resistance risk assessment, factors affecting the resistance development and resistance management were discussed. |
