摘要: Native to China, the Chinese tallow, Triadica sebifera (Euphorbiaceae) is an aggressive woody invader in southeastern United States. The flea beetle, Bikasha collaris (Coleoptera: Chrysomelidae), a common herbivore attacking this plant China. To evaluate its potential as biological control agent host specificity and impact were studied range of B. was evaluated on 68 species 20 families through no-choice choice tests. Adults only survived fed plants from genus while larvae developed successfully T. Under conditions, adults showed distinct preference for over other species. above- belowground herbivory growth garden.B. could reduce stem height, total biomass, number leaves diameter at density 10 individuals per plant. Above- had similar effects parameters. results study suggested that though further tests native North American are needed.
