摘要:

【目的】研究苹果蠹蛾幼虫寄主转移至核桃后的为害习性。【方法】在和田县连续2 a进行室内外幼虫蛀果习性观察。【结果】卵初产半透明色后逐渐加深,卵发育完全后,幼虫咬破卵壳爬出,不取食卵壳,取食核桃的幼虫龄数分为6龄;于叶片上孵化的幼虫,低龄期(1~3龄)取食叶片后转至果实为害,幼虫危害核桃果实时,由外果皮蛀不规则虫道向核仁蛀入,第1代幼虫于4龄开始转果,第2代于3龄末期开始转果,后持续在外果皮为害并多次转果,至幼虫发育完成后脱果,脱果幼虫多自上而下转移至树干60 ~ 120 cm范围内结茧化蛹,幼虫存在滞育现象。【结论】苹果蠹蛾共经历6个龄期,不同世代和龄期的幼虫为害习性有所差异,其为害习性受着卵位置、幼虫龄期和果实发育影响。

Abstract:

【Objective】 The codling moth(Cydia Pomonella L.)is an important quarantine pest in China.In 2018, it was found to harm walnut fruits in Hotan area of Xinjiang, which was the first report in China.This project aims to clarify the harmful habit of the larval host of Cydia pomonella transferred to walnut.【Methods】 The fruit eating habits of larvae were observed in Hotan County for two consecutive years.【Results】 The results showed that the translucent color of the eggs gradually deepened after the initial production.After the eggs were fully developed, the larvae chewed through the egg shell and crawled out without feeding on the egg shell.On the blade hatched larvae, the young period(1-3 instar)transferred to the fruit after feeding blade, larvae damage of walnut fruit, the epicarp irregular way to nucleoli moth corrupteth into the cavity, 1 generation larvae in 4 age began to turn, the second generation in the late age of 3 began to turn fruit, after continuous outer peel and repeatedly turn fruit, after the completion of the larval development to take off the fruit, The larvae migrated from top to bottom and formed cocoons and pupated within 60-120 cm of the trunk, and diapause was observed.【Conclusion】 In conclusion, there were six instars of codling moth.Larvae of different generations and instars had different damage habits, and their damage habits were affected by egg position, larval instar and fruit development.

Key words: Cydia pomonella; walnut fruit; hazard habit; pupation place
