摘　　要：研究了甜菜夜蛾2龄末幼虫被淡足侧沟茧蜂寄生及核型多角体病毒感染后,寄主体长、体宽、头壳宽度及体重的变化。结果表明:各处理组形态学指标均低于对照组,表明甜菜夜蛾在被寄生及感毒后,其生长发育受到了明显抑制。After Spodoptera exigua larvae at the late 2nd stadium were parasitized by Microplttts pallidipes and infected by nuclear polyhedrosis virus, the variations of their body length and width, head capsule width and body weight were investigated. The result showed that the morphological indexes of both parasitic group and infected group were lower than those of the control group, revealing that the development of S. exigua larvae was inhibited obviously after being parasitized by M. palli dipes and infected by the virus.
