摘　　要：【目的】为了解河南省粘虫田间种群的生物学特性。【方法】本文对漯河、洛阳、潢川和原阳的1代或2代粘虫田间种群进行了室内饲养,并对幼虫存活,被寄生情况和繁殖能力等进行了研究。【结果】东方粘虫雌蛾和雄蛾的平均寿命分别为(13.73±4.13)d和(23.04±6.89)d,平均产卵前期和平均产卵历期分别为(6.30±0.33)d和(6.69±2.46)d,单雌平均产卵量为(1631.0±66.83)粒。劳氏粘虫雌蛾和雄蛾的平均寿命分别为(13.17±2.70)d和(13.52±3.62)d,平均产卵前期和平均产卵历期分别为(4.03±0.22)d和(8.28±2.71)d,单雌平均产卵量为(912.9±72.82)粒。潢川地区东方粘虫中线虫的寄生率最高(26.0%),漯河地区2代粘虫寄生蜂的寄生率最高(77.5%)。【结论】河南省内发生危害的粘虫主要为东方粘虫Mythimna separata(Walker)和劳氏粘虫Mythimna loreyi。不同地区不同世代东方粘虫的成虫寿命和产卵量没有显著差异,但幼虫中线虫和寄生蜂的寄生率存在明显差异。东方粘虫和劳氏粘虫在雄蛾寿命,产卵前期和单雌平均产卵量等方面均存在显著差异。[Objectives] To understand the biological characteristics of populations of armyworms in Henan province. [Methods] Individuals were collected from populations in four areas; Luohe, Luoyang, Huangchuan and Yuanyang, reared indoors, and their larvae survival, parasitism rate and reproductive capacity, measured and compared. [Results] Adult female and male longevity, average pre-oviposition period, oviposition period and average female fecundity of Mythimna separatawere(13.73±4.13) days,(23.04±6.89) days,(6.30±0.33) days,(6.69±2.46) days and(1631.0±66.83), respectively, and the corresponding values for Mythimna loreyi were(13.17±2.70) days,(13.52±3.62) days,(4.03±0.22) days,(8.28±2.71) days and(912.9±72.82), respectively. Among different populations of M. separata, the highest level of nematode parasitism was found in the Huangchuan population(26.0%), and the highest level of parasitic wasp parasitism was found in the second generation of the Luohe population(77.5%). [Conclusion] M. separata and M. loreyi are the main armyworm species in Henan. There was no significant difference in the adult longevity and fecundity of first or second generation M. separata from different regions, but there was a significant difference in the level of parasitism by nematodes and parasitic wasps. There were also significant interspecific differences in male moth longevity, the previposition period, and average female fecundity between M. separata and M. loreyi.
