Selection of pupation habitats by Rhynchites foreipennis larvae

Rhynchites foreipennis Fairmaire is a key pest impairing pear’s yield and quality.The experiment was made in the laboratory that mature larvae of Rhynchites foreipennis was selected depth of different soil types and habitat for its pupating.The results showed the pupating depth of Rhynchites foreipennis was sandy ＞dark brown soil＞red soil.In terms of sandy soil compactness’s impact， the larvae pupation’s depth increased with reduction of soil compaction.And， the larvae pupation showed a strong preference for the soil which was shaded， moist and coarse particle.The results are useful for integral control of Rhynchites foreipennis’s larvae and pupae.
