【Abstract】 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.更多还原
