| 摘 要： | 运用2因素2次回归正交旋转组合设计,研究了温度和光照周期对淡足侧沟茧蜂Microplitis pallidipes Szepligeti寄生率和性比的影响,并建立了回归模型,旨在为优化寄生蜂雌性比率、提高寄生率提供资料。主效分析表明,温度、光周期与寄生率呈抛物线关系,编码值为零水平取值时,寄生率达到最大;温度对雌性比率的影响大于光周期。交互作用表明,温度和光周期对斜纹夜蛾Spodoptera litura Fabricius幼虫被寄生率有明显的负交互效应,而对侧沟茧蜂雌性比率的交互作用不明显。通过对模型进行模拟,温度为28℃、光周期L∶D=12∶12时,寄生率达到最大(71.89%);温度为33.7℃、光周期为L∶D=12∶12时,雌性比率达最高值(0.57)。 |

| Abstract: | The influence of temperature and photoperiod on the parasitism rate of the larvae of Spodoptera litura Fabricius and the female ratio of Microplitis pallidipes Szepligeti was evaluated by quadratic orthogonal rotation regression design with two factors,producing two models.These models can provide a basis for optimizing the breeding environment of M.pallidipes.Main effects analysis showed that the relationship between temperature,photoperiod and parasitic rate was parabolic.When the coding value was zero,th... |
