葡萄透翅蛾的习性与防治策略探讨

葡萄透翅蛾足1年发生1代,一生只交配1次。其羽化、求偶、交配、产卵、孵化等生理活动都在白昼进行。初孵幼虫在孵化后2小时左右蛀入葡萄嫩茎,此后在茎内生长、越冬、化蛹直至羽化,防治困难,是葡萄生产的大患。本文根据葡萄透翅蛾习性特点,提出运用性引诱剂测报蛾情、抑制交配,把幼虫消灭在发生或为害之前的策略。

ON THE BEHAVIOUR AND CONTROL TACTICS OF GRAPE CLEAR-WING MOTH

The grape clear-wing moth Paranthrene regalis Butler is one of the noxious diurnal moths,i.e.its mergence,courtship,copulation,ovi-position,and hatching,etc.all happen at daytime,with one generation a year and only one mating during adult life,It is rather difficult to control this insect,because its larvae can bore into the tender stems about two hours after hatching,and develop,overwinter,pupate,and until emergence within the stem. In this paper,a preventive control tactics,the application of sex pheromone to interfere its mating action,is proposed based on the cha-racteristics of the moth''s behaviour.
