【摘要】 在恒温(28±1)℃、恒湿(80±5)%RH条件下,研究了莲雾、芒果、荔枝、龙眼、毛叶枣、木菠萝等6种食料植物对棉古毒蛾的生长发育和繁殖的影响。结果表明,棉古毒蛾能在这6种食料植物上完成其世代循环。其发育历期、雌蛹重、存活率、成虫繁殖力和寿命等,在6种寄主植物间均存在显著差异,其中莲雾和芒果是最适宜的寄主植物,荔枝和龙眼是不适宜的寄主植物。更多还原

【Abstract】 The effects of 6 food plants (Syzygium samarangense, Mangifera indica, Litchi chinensis, Dimocarpus longan, Zizyphus mauritiana and Artocarpus heterophyllus) on the development and reproduction of Orgyia postica (Walker)(Lepidoptera:Lymantriidae) were studied under constant temperature (28±1)℃ and relative humidity (80±5)%. The results showed that O.postica could completed their life cycle when fed on the 6 food plants, all of which should be its host plants, and there were significant differences of the development duration, female pupa weight, survival rates, fecundity and adult longevity etc. among the O.postica fed on the 6 host plants. S.samarangense and M.indica were suitable host plants but L.chinensis and D.longan were unsuitable.更多还原
