摘　　要：研究了相对湿度(RH)对褐背小萤叶甲生长发育的影响,结果表明,在不同RH下,褐背小萤叶甲各虫态的发育历期、存活率、成虫繁殖力和成虫寿命明显不同.卵期、幼虫期、蛹期、产卵前期、世代历期、孵化率、幼虫存活率、羽化率、成虫平均产卵量均与湿度呈抛物线模型关系.不同RH下的成虫产卵期存在显著性差异,在75%RH下最长,达到59.25d,在95%RH下最短,仅24.17d.不同RH下的雌、雄成虫的寿命也明显不同,均为75%下最长,雌成虫达到65.00d,雄成虫57.19d.This paper deals with the influence of relative humidity (RH) on the development of Galerucella grisescens (Joannis). At different RH conditions in the range of 45% RH-95% RH, the duration and survival of various stages, fecundity and adult longevity were significantly different. The relationships of the duration of egg, larva, pupae, pre-oviposition, generation; the survival of egg, larva, pupae; the fecundity to RH were described as parabolas. The longest oviposition period (59.25 days) was recorded at 75% RH, while the shortest (24.17 days) at 95% RH. The longest adult longevity of female and male were also recorded at 75% RH, which were 65.00 days and 57.19 days respectively.
