摘　　要： 在恒温条件下研究了温度对美洲斑潜蝇（ＬｉｒｉｏｍｙｚａｓａｔｉｖａｅＢｌａｎｃｈａｒｄ）生长发育的影响，并分别用线性回归模型和Ｓｔｉｎｎｅｒ模型模拟温度与该害虫生长发育的关系结果表明，在广州地区美洲斑潜蝇１ａ可发生１６个世代；在温度为１３～３４℃范围内，美洲斑潜蝇各虫态发育历期均随温度的升高而缩短；其卵、幼虫、蛹及世代的发育起点温度分别为９．３３２、９．５７２、９．４４３和９．５７２℃；最大发育速率温度分别是３２．５０、３２．００、３１．５０和３１．５０℃；相应虫期的有效积温分别是４６．８７２、７８．９２０、１５４．１４６和２８３．２２８日度各龄幼虫间发育起点温度。 The development of the vegetable leafminer, Liriomyza sativae Blanchard on bean( Vigna sesquipedalis ) at constant temperatures was studied in laboratory. Both regression equation and Stinner model were developed to analyze the relationship between temperature and the development rate of the leaf miner. The results indicated that a total of 16 generations of the leafminer occurred in vegetable area in Guangzhou a year. The development periods became shortened with the temperature increasing at the range of 13 to 34 ℃ . The lower development rate thermal thresholds(LDTT) of its egg, larvae, pupae and a generation were estimated to be 9.332,9.572,9.443 and 9.572 ℃,respectively, while the temperature of the maximum development rate were 32.50, 32.00, 31.05 and 31.50 ℃, respectively. The effective accumulated temperatures for egg, larval, pupal stage and a generation were 46.872 day degree, 78.920 day degree, 154.146 day degree and 283.228 day degree, respectively. Among instars of larvae, the 3rd instar had lowest LDTT and highest UDTT ,and also the largest effective accumulated temperature.The UDTT of the pest of development was estimated to be 36 ℃.
