摘要乌桕原产于中国，学名Triadica sebifera L。小（大戟科），是一种入侵植物在美国东南部。卷叶象甲Heterapoderopsisbicallosicollis Voss是我国常见的一种食草动物。评价其作为烟草赤星病菌生物防治剂的潜力。对该象的生物学特性和寄主专一性进行了研究。H. bicallosicollis在广泛的原生地理范围内发生，并且其未成熟体在15-35°C下成功发育，表明其在目标植物在美国生长的整个气候条件范围内建立和持续的生理潜力。成虫在叶子上挖食孔。在产卵之前，雌性会做一个密封的叶子卷，称为巢，然后在里面产一到两个卵。卵、幼虫和蛹在巢内发育，幼虫只有在巢内发育时才能存活。这种要求使得象鼻虫对T.在对8科54种植物的室内无选择试验中，成虫仅取食3种植物，即乌桕树甲和乌桕树甲。sebifera、乌桕Sapium chihsinianum S. K. Lee和叶下珠（Phyllanthus urinaria L.）只在T.皮脂腺在多项选择试验中，成虫仅在T上产卵，证实了这些结果。皮脂腺鉴于T. sebifera是美国唯一的一种Triadica属植物，本研究结果表明，H. bicallosicollis是一种很有潜力的生物防治剂。sebifera，应考虑进口到美国进行检疫，以便对北美本土物种进行进一步测试。
ABSTRACT Native to China, Chinese tallow, Triadica sebifera L. Small (Euphorbiaceae), is an invasive plant in the southeastern United States. The leaf-rolling weevil, Heterapoderopsis bicallosicollis Voss, is a common herbivore attacking this plant in China. To evaluate its potential as a biological control agent of T. sebifera, biology and host specificity of this weevil were studied in China. H. bicallosicollis occurs over a wide, native, geographic range and its immatures successfully develop at 15–35°C, indicating its physiological potential to establish and persist throughout the range of climatic conditions where the target plant grows in the United States. Adults make feeding holes on leaves. Before oviposition, the female makes a sealed leaf roll called a nidus and then lays one to two eggs inside. Eggs, larvae, and pupae develop within nidi, and larvae survive only when they develop inside the nidi. This requirement makes the weevil highly host specific to T. sebifera, In laboratory no-choice tests of 54 species from eight families, adults fed on only 3 plant species, T. sebifera, Sapium chihsinianum S. K. Lee, and Phyllanthus urinaria L. and only oviposited on T. sebifera. These results were confirmed where, in multiple-choice tests, adults only oviposited on T. sebifera. Given that T. sebifera is the only species in the genus Triadica in the United States, the results of this study suggest that H. bicallosicollis is a potential biological control agent of T. sebifera and should be considered to be imported into quarantine in the United States for further tests on native North American species.
