摘  要:[ Objective] Coffee bean weevil (Araecerusfasciculatus De Geer) is a worldwide important pest in storehouse, which distributes in tropical and subtropi- cal region, having overlapping ecological zone with the important biofuel plant Jatropha curcas L.. The paper was to investigate the damage of coffee bean weevil on J. curcas. [Method] Taking planting area in Luodian County of Guizhou Province as the investigation point, the forest stand of J. curcas in field and the indoor stored fruits were investigated, and the occurrence condition and damage consequence of the pest were grasped. Furthermore, the taxonomic status of the pest was also confirmed. [ Result] Coffee bean weevil had common distribution in planting area of J. curcas in Luodian, which was found to cause damage beth in field and indoor condition. The adults of coffee bean weevil fed on fungi with little direct damage on the fruit of J. curcas. However, the adults of the post laid their eggs in- side the peel of fruit, and the larvae hatched and fed inside the peel, resulting in the collapse of the peels, thus causing direct damage on the fruit. In addition, coffee bean weevil might have series of potential damages including direct feeding on seeds, spreading diseases, and posing damage on other economic crops in pro- duction area, etc.. [ Conclusion] J. curcas was an important new host for coffee bean weevil. The pest had certain damage on the plant, which also had potential damage on plant products and other economic crops. The research and control efforts on coffee bean weevil should be strengthened.[ Objective] Coffee bean weevil (Araecerusfasciculatus De Geer) is a worldwide important pest in storehouse, which distributes in tropical and subtropi- cal region, having overlapping ecological zone with the important biofuel plant Jatropha curcas L..
