研究了地中海粉蛾Ephstia kuehniella Zeller(鳞翅目：Pyralidae)对多种害虫鳞翅目幼虫的常见天敌--多食性小蜂的寄主适宜性。当卵在接近完全发育的库尼拉幼虫(鲜重，20.0毫克)中产卵时，估计成蜂出现的概率为80%或更高。羽化成蜂体大小随着产卵时寄主幼虫初始体重的增加而增大。在斜纹夜蛾上饲养的成蜂的鲜重约为自然寄主斜纹夜蛾的60%，其一生的繁殖力约为斜纹夜蛾的一半。库尼氏黄蜂是一种适合大规模饲养的寄主，但还需要进一步的研究来增加黄蜂的体型，以便将其作为生防剂进行更多的实际应用。
We investigated the host suitability of the Mediterranean flour moth Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) for a polyphagous koinobiont endoparasitoid Meteorus pulchricornis (Wesmael) (Hymenoptera: Braconidae), a common natural enemy of various pest lepidopteran larvae. The estimated probability of adult wasp emergence was 80% or higher when eggs were laid in nearly fully grown larvae of E. kuehniella (fresh weight, > 20.0 mg). The body size of emerged adult wasps increased with the initial weight of the host larvae at oviposition. The fresh weight of adult wasps reared on E. kuehniella was approximately 60% of that when reared on a natural host Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae), and the lifetime fecundity of wasps reared on E. kuehniella was approximately half of that when reared on S. litura. Ephestia kuehniella was shown to be a positive host candidate for the mass rearing of M. pulchricornis, but further investigation is needed to increase the body size of wasps for more practical use of this species as a biocontrol agent.
