Abstract: A laboratory experiment with different kinds of plant leaves showed that Anomala corpulenta adults had an obvious tendency to select Ricinus communis leaves, with the selection rate in a pair-test reached to 90% and 60% or more in the absence and presence of other host plant eaves, respectively. A. corpulenta adults preferred Arachis hypogaea, Ulmus pumila, and Glycinemax leaves to feed with, the feces weight excreted after 12 h being (37.05±9.30) mg, (35.25±4.72) mg, and (16.75±3.18) mg, respectively, followed by Abutilon theophrasti leaves. However, the leaf amount of R. communi consumed by and the feces weight excreted from A. corpulenta adults within 12 h were only (050±018) mg and (0.25±0.13) mg, respectively, illustrating that the selection of R. communi by A. corpulenta adults was not for feeding.
