【目的】 解决大麦资源匮乏而水稻资源丰富的国家或地区人工大量繁育赤眼蜂Trichogramma spp.所需中间寄主卵麦蛾Sitotroga cerealella卵的生产技术，以扩大赤眼蜂防控害虫的应用和规模。【方法】 通过麦蛾生物学指标及赤眼蜂质量控制指标的对比，在室内开展稻谷饲养麦蛾的可行性研究。【结果】 稻谷饲养的麦蛾幼虫蛀食率和成虫羽化率分别为89.6%和88.9%，每千克稻谷能产出麦蛾成虫1 976头，可收集麦蛾卵13.4 mL（约9.0 g），雌蛾平均体长和展翅宽分别为5.5和10.1 mm，雄蛾平均体长和展翅宽分别为5.1和9.6 mm；麦蛾卵的平均长度和宽度分别为0.6和0.2 mm；利用稻谷繁殖的麦蛾卵饲养赤眼蜂，其寄生率、羽化率、雌蜂率、蜂畸形率分别为88.8%、96.0%、58.9% 和7.8%；这些指标与利用大麦饲养的麦蛾均无显著性差异（F=0.089，P=0.935；F=0.885，P=0.443；F=0.224，P=0.835；F=0.141，P=0.895）。【结论】 利用稻谷可大量繁殖麦蛾，为当地赤眼蜂生产提供足够的中间寄主卵，是推广应用天敌赤眼蜂进行害虫生物防治的必要条件。

  [Aim]  To assess the feasibility of rearing Sitotroga cerealella on paddy rice, to determine if the large-scale production of S. cerealella eggs for rearing Trichogramma spp. for biological control is possible in regions where barley resources are scare but rice is abundant. [Methods]  A feasibility study for rearing S. cerealella  on paddy rice was conducted under laboratory conditions by comparing various biological indicators of S. cerealella  and a quality control index for Trichogramma spp.. [Results]  The larval boring rate and adult emergence rate of S. cerealella reared on paddy rice were 89.6% and 88.9%, respectively. One kilogram of paddy rice could yield 1 976 S. cerealella moths, which produce 13.4 mL (approximately 9.0 g) of eggs. The average body length and forewing width of female moths were 5.5 and 10.1 mm, respectively, and those of male moths were 5.1 and 9.6 mm, respectively. The average length and width of S. cerealella eggs were 0.6 and 0.2 mm, respectively. Using S. cerealella eggs reared on paddy rice to rear T. ostriniae resulted in a parasitism rate of 88.8%, an emergence rate of 96.0%, a female ratio of 58.9% and a deformity rate of 7.8%. These parameters were not significantly different to those of barley-reared S. cerealella (F=0.089，P=0.935；F=0.885，P=0.443；F=0.224，P=0.835；F=0.141，P=0.895). [Conclusion]  Rearing S. cerealella on paddy rice enables the mass of Trichogramma spp. in regions where rice is abundant and barley is not commonly grown.
