(一)桔实蝇是为害柑桔果实的重要害虫.能随着鲜果的调运而传播.过去,仅知分布于日本和我国台湾省,现已查明在广西的宁明、凭祥、融安、阳朔和贺县亦有生,这是我国大陆上发生的首次记载.应列为我国对内对外植物检疫对象,严格执行检疫制度,杜绝蔓延与传播.(二)桔实蝇在广西一年发生一代,绝大部分以蛹在桔园表土中,个别以幼虫在被害落果中越冬.(三)桔实蝇的发生与环境关系密切.一般山地桔园,荫蔽度大,被害常较重;反之则轻.(四)成虫有趋化性,喜食糖、酒、醋等物质.在成虫活动盛期,利用蜜糖13份,酒3份,水200份,配成诱杀液,吊装于树冠上;或用1000倍90%敌百虫加3%红糖,选喷于枝叶茂密处,每株喷药液2—3斤,诱杀成虫,都有一定的效果.(五)摘除有虫青果,及时拾毁落果.落果初期每5-7天一次,盛期至末期每天一次.拾集后,采用浸、埋、烧、烫等方法,都可以杀死果内幼虫.(六)利用蛹在表土越冬的习性,如冬季桔园能犁翻表土过冬,既可直接铲伤蛹体,又能暴露蛹体,增加冻死和被鸟雀啄食的机会,也可能有一定的防治效果.
(1) The fruit fly is an important pest that damages the citrus fruit and can be spread with the transport of fresh fruit. In the past, only known in Japan and Taiwan Province of our country, it has been identified that Ningming, Pingxiang, An, Yangshuo and He County are also born, which is the first recorded in mainland China should be listed as China’s domestic and foreign plant quarantine object, strictly enforce the quarantine system to prevent the spread and spread. (2) fruit fly in Guangxi one The occurrence of a generation in the year, the vast majority of the pupa in the orange garden topsoil, individual larvae wintering in the victimized fruit drop. (3) the occurrence of orange fruit fly and the environment are closely linked to the general mountain orangery, shade, often heavier victims (4) adults have chemotaxis, like sugar, wine, vinegar and other substances in the active stage of adult activity, the use of honey 13 parts, 3 parts of wine, 200 parts of water, dubbed trap liquid, hoisting Tree top; or 1000 times 90% trichlorfon plus 3% brown sugar, the election spray in the dense foliage, 2-3 kg per plant spray liquid, trapping adults, have a certain effect. , Pick up and drop fruit in time.Flowering every 5-7 days once in early, peak to last period once a day.After collecting, using immersion, burying, burning, hot and other methods, can kill (6) The habit of using the pupae to winter in the topsoil, such as the winter orange garden can plow the topsoil over the winter, can directly scrape the pupa body, but also expose the pupa body, increase the chance of freezing to death and being pecked by birds, May also have some control effect.
