本文报道了寄生蜂玉米螟赤眼蜂（Trichogramma ostriniae, Pang et Chen）在四种人造寄主(Ostrinia nubilalis (Hubner), Sitotroga cerealella （Olivier), Trichoplusia ni （Hubner）和辐射后的kuhniella (Zeller)）卵上的表现。我们测量了9 ~ 11代的寄生蜂寿命、个体和种群的寄生水平、后代的羽化存活率和后代的性别比。从每个来源饲养的黄蜂在源宿主和目标宿主欧洲玉米螟（O. nubilalis）上进行测试。在试验条件下，库尼埃氏菌为不良寄主，T. ni和O. nubilalis为良好寄主，谷杆菌为中间寄主。我们没有发现在交替寄主上饲养许多代会降低目标寄主O. nubilalis的表现的证据。性别比例偏向于女性，并且不会随着时间的推移而改变。随着时间的推移，用谷杆菌和库尼氏杆菌饲养的黄蜂的性能可能有所提高。我们讨论了从寄生蜂性能的不同测量中获得的信息，以及在实验室条件下随时间变化性能的可能原因。(C) 2001学术出版社。
The 'performance of the parasitoid Trichogramma ostriniae (Pang et Chen) on eggs of four factitious hosts, Ostrinia nubilalis (Hubner), Sitotroga cerealella (Olivier), Trichoplusia ni (Hubner), and irradiated Ephestia kuhniella (Zeller), is presented. We measured parasitoid longevity, individual and population levels of parasitism, survival of progeny to emergence, and progeny sex ratio for 9 to 11 generations in laboratory colonies. Wasps reared from each source were tested on the source host and on the target host, European corn borer (O. nubilalis). Under the conditions tested, E. kuhniella was a poor host, T. ni and O. nubilalis were good hosts, and S. cerealella was intermediate. We found no evidence that being reared for many generations on an alternate host decreased the performance on the target host, O. nubilalis. Sex ratio was female biased and did not change over time. There may have been an increase in performance of wasps reared on S. cerealella and E. kuhniella over time. We discuss the information gained from different measures of parasitoid performance and the possible causes for variation in performance over time under laboratory conditions. (C) 2001 Academic Press.
