The resistance of 473 common bean resources to Acanthoscelides obtectus was identified by artificial inoculation method. The results showed that 49.1% of the resources showed varying degrees of resistance, mcluding 15 highly resistant resources, 60 resistant resources and 157 moderately resistant resources. In the highly resistant resources, F1432, F0645, F0675, F0004351 and F0004406 did not show any infected symptoms, manifesting as immunity. Research found that A.obtectus has a certain phototaxis. No significant differences in resistance were found among resources with different grain color, grain size, and seed coat luster. The screening and identification of A.obtectus resistant resources is beneficial for providing excellent resistance resources for subsequent resistance breeding.
