湖南省柑橘大实蝇研究初报

A Preliminary Study on Chinese Citrus Fly in Hunan Province

为了减轻柑橘大实蝇对湖南省柑橘产业的危害程度,对柑橘大实蝇的田间消长规律、成虫习性、危害特点及防治方法进行了研究。结果表明:湖南省柑橘大实蝇的产卵盛期在6月中旬~7月中旬,孵化盛期在8月下旬~9月中旬,化蛹盛期在11月中下旬,羽化盛期在5月中下旬;成虫有喜阴避高温习性,成虫羽化主要是白天,上午比下午羽化的多,晚上和下雨天几乎不羽化;受柑橘大实蝇影响最严重的是脐橙,其次是温洲蜜柑和冰糖橙,影响较轻的是椪柑。研究还发现,橘园及周围地面喷施诱杀剂,以及采用塑料袋药剂薰蒸闷杀处理虫果,对控制柑橘大实蝇危害的效果较好。

In order to decrease the damage degree of Chinese citrus fly to citrus industry,this study researched the growth and decline law of Chinese citrus fly,the adult behavior,the damage characteristics and the control methods.The experiment results showed that the spawning period of Chinese citrus fly in Hunan province is from second ten days of June to the second ten days of July;the hatching period is from the last ten-day of August to the second ten-day of September;the peak stage of pupation is in late November;the emergence stage is in mid and late May.The adult favor cool place and avoid high temperature,and its emergence appears in daytime,which in the morning are more than the ones in the afternoon,and there is almost no emergence at night and rainy day.Citrus is influenced most seriously by Chinese citrus fly,and then is Satsuma mandarin and Bingtang orange,and there is least obvious influence to Ponkan.The experiment also showed that spraying attractive toxicant in orange garden and around ground and adopting reagent in plastic bag to fumigate fruits with Chinese citrus fly are effective control measures.
