中文摘要：文章概述橘小实蝇Bactrocera dorsalis (Hendel)生活史、地理分布和生态要求的基础上，分析温度、湿度、降雨以及气候因子与橘小实蝇生长发育的关系，以及对橘小实蝇地理分布的影响。综述结果表明：喜湿热，厌干冷是橘小实蝇主要的生态学特征，低温与干旱不利于其生长发育；温度是橘小实蝇纬度分布中最主要的影响因子，冬季低温是中高纬度分布的主要限制因子，夏季高温是低纬度地区的限制因素之一，降雨影响橘小实蝇在经度上的分布范围。
英文摘要：Based on the life history, geographical distribution and requirement for the ecological environment of Oriental fruit fly, Bactrocera dorsalis (Hendel), the relationship between its growth and climatic factors were analyzed in order to clarify the influence of temperature, humidity, rainfall and other climatic factors for the geographical distribution. The results showed that Oriental fruit fly tended to live in the wet and hot environment, but low temperature and drought was detrimental to its growth and development. Temperature was the main factor on the latitudinal distribution, i.e., low temperature in winter was the major limited factor in middle and high latitudes, and the high temperature in summer was one of the limited factors in the low latitudes. Rainfall may influence the longitudinal range of Oriental fruit fly.
