【摘要】 在 15 - 30℃温度范围内 ,观察了不同梯度温度下黄色潜蝇茧蜂 Opius flavus Weng et Chen生长发育的历期 ,并对实验数据采用直线性回归的方法处理。结果表明 :黄色潜蝇茧蜂卵、幼虫、蛹的发育起点温度分别为 8.5 18℃、9.90 9℃和 8.6 5 6℃ ,其有效积温分别为 6 0 .2 7日度、6 5 .75日度和 87.78日度 ;卵——成虫的发育起点温度是 9.6 31℃ ,有效积温为 2 0 3.0 4日度。更多还原

【Abstract】 Effect of temperature on the development of Opius flavus at the range of 15-30℃ was studied. The threshold temperature of development for the egg, larva, pupa and egg-to-adult of Opius flavus were 8.518℃?9.909℃?8.656℃ and 9.631℃, respectively. The effective accumulative temperature for these stages were 60.27?65.75?87.78 and 203.04 day-degrees, respectively.更多还原
