| 摘 要： | 阐述了环境因素对昆虫滞育诱导的影响。在所有的环境因子中 ,光周期是最重要的滞育诱导因子 ;温度在滞育诱导中也发挥着重要的作用 ,在热带地区昆虫中 ,温度常作为滞育诱导的主要刺激因子 ;食料、密度和湿度对滞育诱导的作用相对较小 ,但在一些依赖季节性食料才能生存的植食性和捕食性昆虫中 ,食料可作为滞育诱导的主要因子 ;在一些贮粮害虫中 ,密度对滞育诱导起着主要作用

| Abstract: | This paper reports the influence of environmental factors on induction of diapause in insects. Among all environmental factors, photoperiod is the most important in induction of diapause. Temperature also plays an important role in the induction of diapause. Temperature may be the primay diapause-inducing cue in tropic zone insects. Food, density and moisture are less influential than photoperiod and temperature in induction of diapause. However, food may be a major factor in the induction of diapause among some phytophagous and predatory insects, which depend on seasonal food to survive. Density plays a major role in some pests of stored products. |
