套袋梨病虫害研究综述与展望

套袋技术是目前生产高档梨果的重要措施之一,梨果套袋后避免了与外界的直接接触,减轻了病虫危害,提高了果面光洁度和果实的商品价值。但果袋所提供的微域环境加重了梨果黑点病、褐斑病、中国梨木虱、黄粉蚜等病虫害的发生。文章综述了套袋梨主要病虫害的研究现状、发生规律及防治方法,以期为梨果的无公害化生产奠定理论基础。

Summary and prospect of the control of pear disease and insect pests by bagging

Pear fruit bagging is one of the most important practices in producing high quality fruits.Bagging pear fruit can avoid direct contact with the outside,reduce the plant disease and insect pests,enhance the fruit surface smoothness,and increase the fruit goods value.However,the exceptional environment inside the fruit bag often induces some fruit diseases and insect pests,such as pear black-dot,pear brow spot,Psylla Chiesis Yang et Li,Aphanostigma jakusuienis Kishida etc.Recent research on the familiar fruit diseases and insect pests(listed above) after bagging is summarized so as to lay theoretical basis for non-pollution production of pear.
