中文摘要:
      芙新姬小蜂Neochrysocharis formosa是潜叶蝇类害虫的优势天敌。在中国已发现孤雌产雌品系(thelytokous strain)和两性品系(arrhenotokous strain)。以实验室连代饲养的芙新姬小蜂两种品系为研究对象,比较了两种品系在5个温度梯度(18、22、26、30和34℃)下未成熟期的生活史参数。结果表明:卵-幼虫历期、蛹历期和整个未成熟期均随温度升高而缩短;相同温度条件下,孤雌品系和两性品系雌蜂的未成熟期的发育历期,在18、22和30℃下均为孤雌品系显著短于两性品系,在26℃下,二者无显著差异,在34℃下则为前者显著长于后者;5个温度下,孤雌品系雌蜂个体大小和卵子数均分别显著低于两性品系雌蜂。综合分析表明,两种品系在未成熟期的生活史特征参数方面发生了较大程度的分化。
英文摘要:
      Neochrysocharis formosa is the dominant natural enemy of the leafminers. Thelytokous and arrhenotokous strains of N.formosa were reported in China and laboratory strains were successfully established. In this study, life history parameters of N. formosa during immature stage were compared between the two strains at 18, 22, 26, 30℃ and 34℃. The results showed that the eggs-larvae, the pupal duration and the whole immature period shortened with the rise of experimental temperature. Under the same temperature conditions (18, 22℃ and 30℃), the developmental duration of the immature stage of the female of the arrhenotokous strain was significantly longer than that of the thelytokous strain, and there was no significant difference at 26℃, but the thelytokous strain was significantly longer than the arrhenotokous strain at 34℃. Under the five temperature conditions, body sizes and the number of eggs of virginal female of arrhenotokous strain were significantly greater than the thelytokous strain. The comprehensive analysis showed that the two strains had a certain degree of differentiation during the immature period.
