摘　　要：在室内自然变温条件下对玉溪市红塔区小叶榕（Ficus concinna）上的榕管蓟马（Gynaikothrips uzeli Zimm）的历期和年发生消长规律进行了调查。结果表明,该虫在红塔区小叶榕上完成1代夏季需要25～31 d,春秋季需要42～47 d,冬季需要54～60 d。随着气温的下降,各虫态历期也相应加长,完成1代的时间也随之延长,榕管蓟马在红塔区一年可发生8～9代,周年可发生,世代重叠严重,卵的发生表现为两个高峰期,第一个高峰时间在7月中旬到10月下旬,第二个高峰时间在1月中下旬至2月中下旬,第一个高峰期发生数量大于第二个高峰期,其发生数量与温度关系密切,与降水有一定的关系。The developmental duration and change rules of Gynaikothrips uzeli Zimm on Ficus concinna was investigated at yuxi hongta district. The results showed that G. uzeli needed 25 to 31 d in summer complete generation, which needed 42～47 d in Spring and Autumn and 54 to 60 d generation in winter complete. As temperatures drop, the state of insect correspondingly became lengthen, complete generation time became lengthen, G. uzeli could happen 8 ～9 generations a year in hongta district. G. uzeli could occur on the Hongta district flocculus banyan anniversary, overlapping generations. The eggs harm characterized had two peak, the first peak in late time in the middle of July to October, the second peak period in the Mid to late January until Mid to late February. The first peak occured with greater number than the second peak, closely related to the amount and the temperature, and certain relations to precipitation.
