摘要在实验室条件下，研究了黑蓝腹甲的生物学特性和寄主专一性。该虫为一化性昆虫，幼期32-39天，成虫在土壤中越冬。共测试了来自21个科的35种植物。幼虫和成虫均对酸模和酸模有不同程度的危害。我是主宿主。幼虫也攻击两种蓼属植物，P. hydropiper和P. perfoliatum。但成虫与两种蓼属植物不同时发生。虽然产卵发生在其他五种植物，没有一个支持幼虫发育。田间观察表明，G. atrocyanae引起的自然R.人口众多。因此，它被推荐作为一个有价值的生物制剂，该杂草。
Abstract The biology and host specificity of the beetle, Gastrophysa atrocyanea Motch were studied in the laboratory in Nanchang, China. This univoltine insect completed its immature stage in 32–39 days with adult overwintering in soil. A total of 35 plant species from 21 families were tested. Both larvae and adults attacked Rumex japonicus and Rumex acetosa with R. japonicus the main host. Larvae also attacked two Polygonum species, P. hydropiper and P. perfoliatum. But the adults are not concurrent with the two Polygonum species. Though oviposition occurred on five other plant species, none of them supported larval development. Field observations showed that G. atrocyanae caused a progressive decline in natural R. japonicus populations. Thus it is recommended as a valuable biological agent for this weed.
