柑桔花蕾蛆又称柑桔瘿蚊,花蛆、花包虫,属双翅瘿蚊科,是柑桔花期的主要害虫。幼虫为害花蕾,在花蕾子房周围取食,蕾内组织被破坏,花蕾膨大变硬变短,形如灯笼,不能开放,以致脱落。花蛆以老熟幼虫越冬,开春化蛹,来年始花期出土羽化为在虫,在虫产卵于花蕾内,卵孵化为幼虫:再度为害,造在花数减少。据我县山岔、瓦又坡等柑桔园两年内抽样调检,被害率达21～25％,严重影响柑桔产量。鉴于目前对防治花蕾蛆的时期、药剂等难以掌握,因此我们于1986年开展了柑桔花蕾蛆的防治试验,目的在于指导柑桔生产,减少损失。现将试验结果小结如下。
Citrus buds maggot, also known as citrus 瘿 mosquito, flower maggots, flower hydatid, is a double-winged 瘿 mosquito, citrus flowering is the main pest. Larvae damage buds, feed around the buds ovary, bud tissue is destroyed, buds harden and become shorter, shaped like a lantern, can not open, so fall off. Flower maggots to mature larvae overwintering, pupation in the spring, the beginning of the flowering period emerging emergence in insects, insects spawning in the bud, egg hatch larvae: once again damage, made in the number of flowers reduced. According to my county shantui, tile slope and other citrus orchard sampling inspection within two years, the victimization rate of 21 to 25%, seriously affecting the citrus yield. In view of the current period of prevention and treatment of buds maggots, pharmaceuticals and other difficult to master, so we conducted in 1986 to control the citrus bud maggot, the purpose is to guide the citrus production and reduce losses. The test results are summarized below.
