摘要
中国栗(Castanea mollissima Bl.)又称板栗,是重要的木本粮食植物,又是传统的外销果品。但是,以栗食蛾(Cydia splendnoa Hübner)为主的几类害虫,每年于4~5月板栗花期,借栗花授粉途径其卵进入花果,到9~10月的果期发育成幼虫在栗食中长大食害种子,并且将虫粪堆积其中。果实受害后不利贮藏、易霉烂变质更无食用价值。
Some new methods of preventing and get rid of pests of chinese chestnuts is described. The experiments show that the ultrasonic, freezing and the N_2 sealing methods are effective in preventing and deereasing pests.
