中文摘要：

绿眼赛茧蜂Zele chlorophthalmus（Spinola）是草地螟Loxostege sticticalis L.幼虫的重要寄生蜂。但目前国内外对其生物学特性及其发生与温度的关系还没有报道。为了阐明绿眼赛茧蜂的生物学特性,并为其室内扩繁及田间保护利用提供试验依据,本文分别在17、21、25、29和33℃、相对湿度70%±5%、光周期16L：8D条件下,以草地螟3龄幼虫为寄主,研究了其寄生率和生长发育特征的变异,明确了其发育起点温度和有效积温,以及在我国草地螟主要发生危害区的发生为害世代。结果表明,在17-29℃,绿眼赛茧蜂能与寄主建立寄生关系,并能完成发育。其中以21和25℃的寄生率最高（67.3%和60.0%）,子代结茧率和羽化率最高（〉70%）并显著高于29和17℃的。另外,绿眼赛茧蜂的蛹（茧）重和成虫寿命随温度的升高而下降。但在33℃,寄生率为0,不能与草地螟建立寄生关系;在17-25℃,卵-幼虫、预蛹-蛹及世代发育历期随温度的升高而缩短,但在29℃时,发育历期比25℃的有所延长。Logistic曲线和线性模型均可描述绿眼赛茧蜂发育速率与温度的关系,但前者的决定系数（R2=0.935-0.971）比后者（R2=0.859-0.890）高,因而Logistic曲线能更好地反映绿眼赛茧蜂发育速率与温度的关系;卵-幼虫、预蛹-蛹以及世代的发育起点温度依次为8.7、9.9和10.8℃,完成发育所需的有效积温分别为176.0、189.6和331.8日·度。绿眼赛茧蜂在我国草地螟发生危害区可发生2-7代/年。

英文摘要：

Abatract： Zele chlorophthalmus（Spinola） is a solitary koinobiont endoparasitoid parasitizing the beet webworm, Loxostege sticticalis L.（Lepidoptera： Crambidae）, one of the most destructive insect pests of crop and fodder plant in northern China. Variations in parasitism rate and life history parameters of Z. chlorophthalmus were investigated at 5 constant temperatures（17, 21, 25, 29, and 33 ℃） by using the 3rd instar L. sticticalis as host. The parasitism rates at 21 and 25 ℃ were significantly greater than those at 17 and 29 ℃, but no parasitism rate was found at 33 ℃. The pupation and emergence rates at 21 and 25 ℃（70%） were all higher than those at 17 and 29 ℃. The pupal weight and adult longevity decreased with increasing temperature. Developmental duration of eggs, larvae, pre-pupae, pupae, and whole generation decreased lineally with increasing temperature within 17-25 ℃ but extended slightly at 29 ℃. The relationship between temperature and developmental rate of Z. chlorophthalmus was better fitted by the Logistic model（R2=0.935-0.971） than linear model（R2=0.859-0.890）. Threshold temperature for eggs and larvae, pre-pupae and pupae, and full generation was 8.7, 9.9 and 10.8 ℃, respectively, and thermal constant was 176.0, 189.6, and 331.8 day-degrees, respectively. Z. Chlorophthalmus might complete 2-7 generations annually in areas where L. sticticalis occurs and the annual number of generation appeared decreasing with increasing latitude. This data can be useful in determining the potential of using Z. Chlorophthalmus as a biological agent, by optimizing mass rearing and release techniques of the parasitoid.
