Abstract:
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.
