摘　　要：在云南省永善县对橘园蜜柑大实蝇[Bactrocera(Tetradacus)tsuneonis]的日活动规律及空间分布型进行了调查研究。结果表明:蜜柑大实蝇的日活动规律随着天气的变化而变化,其日活动高峰期在晴天为16:00左右,阴天为15:00左右,雨天为11:00左右和14:00左右;在株高2.8 m的橘树上,2.0～2.8 m高度处诱捕到的虫量最大;蜜柑大实蝇雌虫在橘园中总体上呈聚集分布,雌虫个体之间相互吸引,分布的基本成分是个体群,其聚集分布主要是由自身聚集行为和环境异质性共同引起的;雄虫的空间分布主要为均匀分布,小部分为聚集分布。The daily activity and spatial distribution pattern of Bactrocera （Tetradacus） tsuneonis （Miyake） in the orange oro chard of Yongshan county in Yunnan province were investigated and studied. The results showed that the daily activity of Bactrocera （Tetradacus） tsuneonis varied with the change of weather, and its daily activity peak was found at about 16：00 in sunny days, about 15：00 in cloudy days, and around 11：00 and 14：00 in rainy days. The number of this fruit fly captured by yellow traps was the highest at 2.0 ～ 2.8 meter height of 2.8 - m - tall orange trees. The spatial distribution pattern of the female adults in orange orchard was aggregative distribution in general. The females attracted each other, and their distributive basic component was individual colony. The reasons of their aggregation were the aggregated behavior itself and the environmental difference. The male adults in or- ange orchard presented mostly uniform distribution, and partly aggregative distribution.
