不同花粉对玉米螟赤眼蜂寄生功能反应及生长发育的影响
Effects of Different Pollens on the Parasitic Functional Response and Development of Trichogramma ostriniae
摘要
Abstract
Pollen serves as an energy source enhancing the parasitic capacity of parasitoid natural enemies.The effects of pollens collected from four common plant species on the parasitic capacity and development of Trichogramma ostriniae were determined.By fitting parasitic functional response models and observing developmental parameters,we aimed to clarify the regulatory effects of different pollens on the parasitism and development of T.ostriniae,thereby providing a scientific basis for its application and the selection of supplemental food plants.The linear coefficients(P1)of the fitted parasitic functional response models of T.ostriniae fed on Abelmoschus manihot,Zea mays,Brassica napus,and Camellia japonica pollen were-0.040,-0.113,-0.008,and-0.094,respectively,indicating that the functional responses conform to Holling Ⅱ model.T.ostriniae fed on Z.mays pollen exhibited the highest instantaneous attack rate(1.236),indicating the strongest initial host-searching capability.Those fed on B.napus pollen had the shortest handling time per host egg(0.017 days).Parasitism capacity was optimal for wasps fed on A.manihot pollen(67.322).The maximum parasitized hosts for parasitoids fed on B.napus pollen and A.manihot pollen were relatively high(57.200 and 55.318,respectively),indicating their capacity to parasitize more hosts when these pollens are abundantly supplied.The F1 progeny fed on A.manihot and B.napus pollen exhibited significantly shorter immature developmental periods(7.17 and 8.13 days,respectively),high pupal emergence rates(89.44%and 85.33%,respectively),and extended adult longevity(12.27 and 10.97 days,respectively).In conclusion,A.manihot and B.napus pollens significantly enhance the parasitism capacity of T.ostriniae and promote the development of their progeny.Therefore,A.manihot and B.napus are recommended for field planting as supplemental food plants to augment the parasitic capacity of T.ostriniae.关键词
