摘要: 摘要:本研究通过系统评估以白雪灯蛾卵、米蛾卵和亚洲玉米螟卵三种寄主繁育的玉米螟赤眼蜂Trichogramma ostriniae的生物学特性及其对亚洲玉米螟卵的寄生能力,旨在探究白雪灯蛾卵与常用繁育寄主卵对玉米螟赤眼蜂的影响。结果显示,三种繁育寄主繁育的玉米螟赤眼蜂发育历期、羽化率、雌蜂百分比和雌蜂寿命均无显著差异。白雪灯蛾卵繁育的玉米螟赤眼蜂寄生量(169.86粒/雌)显著高于米蛾卵(141.81粒/雌),与玉米螟卵无显著差异(171.17粒/雌);平均单卵出蜂数(2.50头)显著高于玉米螟卵(1.82头)和米蛾卵(1.06头);畸形蜂率显著最高(9.81%);白雪灯蛾卵和玉米螟卵繁育的玉米螟赤眼蜂雌蜂个体大于米蛾卵处理,玉米螟卵繁育的雄蜂个体大于白雪灯蛾卵和米蛾卵处理。三种繁育寄主繁育的玉米螟赤眼蜂对亚洲玉米螟卵的寄生能力无显著差异。综合各生物学指标,三种繁育寄主繁育的玉米螟赤眼蜂在生物学特征指标上存在一定差异,与原寄主亚洲玉米螟卵相比,白雪灯蛾卵是其室内繁育玉米螟赤眼蜂的优良寄主,其次为米蛾卵。研究结果为工厂化高效繁育赤眼蜂奠定了基础。

Abstract: This study systematically evaluated the biological characteristics and parasitic capacity of Trichogramma ostriniae reared on three host eggs, Chionarctia nivea, Corcyra cephalonica, and Ostrinia furnacalis. The results demonstrated that C. nivea-reared parasitoids achieved the highest fecundity (169.86 eggs/female), which is significantly higher than that of C. cephalonica-reared parasitoids (141.81 eggs/female) and comparable to that of O. furnacalis-reared parasitoids (171.17 eggs/female). Additionally, C. nivea eggs yielded the highest number of emerged wasps per host egg (2.50 wasps/egg), significantly exceeding both O. furnacalis eggs (1.82 wasps/egg) and C. cephalonica eggs (1.06 wasps/egg). However, this group also showed a significantly higher malformation rate (9.81%). Female wasps of T. ostriniae reared on eggs of C. nivea and O. furnacalis were larger than those reared on eggs of C. cephalonica, male wasps reared on eggs of O. furnacalis were larger than those reared on eggs of C. nivea and C. cephalonica. No significant differences were observed among the three groups in parasitic capacity. In conclusion, while T. ostriniae wasps exhibit varying biological traits depending on the rearing host, C. nivea eggs emerge as a superior alternative to native host (O. furnacalis) for mass rearing, despite the higher malformation rate, followed by C. cephalonica eggs. These findings provide critical insight for optimizing the industrial production of Trichogramma parasitoids to enhance their application in biological control programs.
