The Lycium fruit fly is a serious pest to the Lycium tree.The fruit of which is usedas a famous Chinese medicine produced in Ningsha,China.The larva of the fly attacks thefruit of the Lycium tree,causing a loss to the annual yield up to 22-55%.The morphological characteristics of different stages of the fly are described in this paperand studies on its life history,especially in connection with its hibernation habit and themethod of control were conducted in Ningsha during the years 1959-1962.Hibernating as pupa in the soil,the fruit fly breeds three generations a year.The firstgeneration larva prevails simultaneusly with the appearance of the fruit of the tree in Juneand July,thus causing serious damages.Eggs are deposited singly inside the fruit,and thelarva lives there on its juice.Coming out through the base of the fruit,the matured larvadrops to the ground and pupates in the soil.According to the result of a series of experiments of soil treatment with several kinds ofinsecticide conducted in the laboratory as well as in the field,the treatment with 6% γBHC6 catties per mow shows better result,aldrin comes second,and DDT and 1068 with com-paratively lower efficiency.

(1)枸杞实蝇 Neoceratitis asiatica (Becker)属双翅目实蝇科(Trypetidae),分布于我国的宁夏、青海和新疆。其幼虫专以枸祀的果实为食。(木巳)果被害率一般为22—55%。(2)实蝇一年发生三代。第一代幼虫发生在结果时期,为害最重,虫口密度最高;第二代次之;第三代最少。以蛹在土内越冬,分布在土下1—3寸处。卵产于果内嫩种子上,每果1卵,幼虫生活在果内,成熟幼虫由果柄附近钻出落地入土化蛹。成虫寿命,雌虫平均14天,雄虫5.5天。卵及幼虫21.6天,蛹18.3天,一个世代约需46.4天。(3)根据三年来防治试验:在越冬蛹羽化以前(约5月上旬),用6%r666粉剂每亩6斤土壤处理,防治初羽化的成虫有效。土面撒布666粉也有一定的效果。摘除蛆果深埋,并撒布6%666粉,亦有实际推广意义。

Elmo Hardy who works in the Hawaii University of U. S. A. to confirm; and they, have told us our identification is correct. In our country, there is not yet any report about the occurence of this fly. Because it damages seriously fruit and vegetable, we should not only maintain sharp vigilance, but also know about it. We have done some research work on its features and habits in Guangzhou, China.

番石榴实蝇,是从泰国产的番石榴上收集的,鉴定后分别再经华南农业大学刘秀琼教授和美国夏威夷大学D.Elmo Hardy教授的复核,证实无误。我国尚未有此虫发生的报道,鉴于其对水果和蔬菜可造成严重的为害,作者在广州对此虫的形态特征和生活习性,进行了较詳细的观察。番石榴实蝇分布于印度、巴基斯坦、斯里兰卡和泰国等印度次大陆和印度支那的部分地区。由于其严重的蛀食致使受害的农作物完全失去商品的价值。尽管目前在我国尚未发现此虫,但如果一旦传入,将会导致不可估量的严重损失。本文主要是通过介绍此虫的主要形态特征以及对其若干生活习性的简略描述,达到对此虫有个初步的了解。
