摘　　要：为了明确橘小实蝇在濮阳地区秋季冬枣园的扩散与越冬规律,于2021年9月至2022年3月通过色板诱集和挖查法,监测冬枣园内不同位置橘小实蝇成虫数量、活动节律、存活虫态越冬情况,结果表明,橘小实蝇成虫偏爱黄板,东北方向诱捕虫量显著高于西南方向,枣园外周虫量明显高于枣园内部虫量;9:00—14:00和14:00—17:00两个时段成虫诱捕量高于或显著高于17:00—09:00诱捕量,即白天诱捕量显著高于夜间;橘小实蝇在濮阳地区冬枣园幼虫和蛹均不能越冬。The dispersal and overwintering habits of Bactrocera dorsalis in winter jujube orchards in the Puyang region during autumn were investigated.The number,activity rhythm,and overwintering status of B.dorsalis adults at different locations were monitored by color board trapping and digging method from September 2021 to March 2022.The results showed that B.dorsali adults exhibited a preference for yellow boards,with a significantly higher catch number observed in the northeast aligned traps compared to the southwest aligned traps.The number of adult fruit flies observed outside the orchard was significantly higher than that obsevrved inside.The number of trapped adults during the hours of 9:00-14:00 and 14:00-17:00 was found to be higher or significantly higher than that during the hours of 17:00-09:00.This indicates that the number of trapped adults during the day was significantly higher than that at night.The larvae and pupae of B.dorsalis were unable to survive the winter in the winter jujube orchard in the Puyang region.
