柑橘花蕾蛆
citrus blossom midge
柑橘花蕾蛆(eitrus blossom midge)在柑橘花蕾内为害的害虫。学名Contari二敌cl’t汀B盯nes。双翅目，瘦蚊科。中国柑橘区都有分布。只为害柑橘类植物。成虫形似小蚊，雌成虫体长1 .5一1.8毫米，暗黄褐色或灰黄色，被有细毛。触角念珠状，14节，各节环生刚毛。翅一对，翅脉简单，翅上密生黑褐色细毛。足细长。雄成虫体长1.2一1.4毫米，灰黄色。触角鞭节每节呈哑铃状，形似2节。卵长椭圆形，无色透明，外包一层胶质物，末端具丝状附属物。’末龄幼虫乳白至橙黄色，长纺锤形，体长约2.8毫米，前胸腹面有一褐色、前端分叉的剑骨片。蛹乳白色，后期复眼和翅芽黑褐色(见图)。 年生1代，少数2代，以末龄幼虫在土中越冬。越冬幼虫于翌年3月化蛹，3一4月羽化出土，以雨后出土最盛。当现蕾后花蕾露白，成虫飞到花蕾上，将产卵器由花蕾顶端插入花蕾内产卵，散产或排列成堆，每雌可产卵60一70粒。年生2代者，第一代羽化后可在晚期柑橘花蕾上产卵为害。凡花蕾顶部结构不紧密或有裂缝、小孔的都有利于成虫产卵。幼虫在花蕾内纸幼丝登子花爹食，受害的花蕾肿大呈灯笼状，不能开花、授粉和结实，终致脱落，过多时影响产量幼虫约经10天后脱蕾落上结茧.以阴雨天入土最多，在树冠周围阴厘米内外表士层6厘米以内的土中虫口密度最大。幼虫体眠至翌年旱春，脱去老茧，逐渐向土面移动，截新结茧化蛹。一般平原、阴湿低洼的柑橘园.有利于成虫活动产卵、末龄幼虫脱蕾入土及上中幼虫的活动壤上和沙壤上保水力强的柑橘园有利于幼虫的生活。春季阴雨利于羽化。干旱之后骤雨，雨后成虫出上尤为整齐。出土后成虫先在地面爬行活动，然后飞行上树防治方法是:①成虫出上前，在树冠周围30厘米内外的地面喷撒甲基对硫磷微囊剂、克百成颗粒剂、二嗓磷颗粒剂、敌百虫、辛硫磷、水胺硫磷、拟除虫菊醋类或杀螟硫磷乳剂;②冬季翻耕或春季浅耕树冠周围土壤;③早期摘除并及时烧毁被害花蕾 (黄郑侃)
