| 摘 要： | 日本追寄蝇（Exorista japonica Townsend）是美国白蛾（Hyphantria cunea Drury）等多种鳞翅目（Lepidoptera）食叶害虫蛹期的重要寄生性天敌,本文对该蝇的发育起点温度和有效积温进行了观察,结果表明在18℃-30℃范围内,日本追寄蝇发育历期随温度的升高而缩短。卵期、幼虫期、蛹期、产卵前期的发育起点温度分别为10.12℃、8.86℃、7.81℃、9.88℃,有效积温分别为59.89日·度、100.2日·度、189.47日·度、20.43日·度;全世代的发育起点温度为8.15℃,有效积温为383.25日·度。 |

| Abstract: | Exorista japonica Townsend was an important pupal parasitoid in Hyphantria cunea Drury and many other Lepidoptera defoliators,this paper observation on developmental threshold temperaturae and effective accumulated temperature of Exorista japonica Townsend.Temperatures range between 18℃~30℃,the durations of different stages of Gastrolina depressa shortened as temperature rising.The developmental threshold temperatures of egg,larva,pupa and pre-oviposition stages was estimated to be10.12℃,8.86℃,7.81℃ and 9.88℃,and the effective accumulated temperatures were 58.89,100.2,189.47 and20.43degree-day,respectively.The developmental threshold temperature was 8.15℃ and the effective accumulated temperature was 383.25degree-day for the whole generation. |
