摘　　要：在恒温条件下观察了温度对豆带蓟马生长发育及繁殖力的影响 ,结果表明 :豆带蓟马卵期、若虫期、前蛹 -蛹以及卵到成虫的发育起点温度分别为 (11.19± 1.2 3) ℃、(12 .5 7± 1.2 6 ) ℃、(12 .6 2± 1.14 ) ℃、(12 .0 7± 1.19) ℃ ,有效积温分别是 (6 9.0 8± 6 .6 3)日度、(85 .0 1± 11.0 7)日度、(5 6 .6 0± 5 .89)日度、(198.89±2 0 .94 )日度。各虫态的发育速率与温度的关系可用直线回归方程来拟合 ,相关系数 (r)均较高。豆带蓟马种群在2 5℃下增长倍数 (I=8.4 9)最大 ,平均每雌虫日产卵量为 2 .2 0粒 。The growth and development of the Teaniothrips glycines Okanoto was studied under the constant temperature from 17 ℃ to 33 ℃. The results showed that the thresholds of development and effective temperature accumulations of its eggs, nymphs, pre pupae to pupae, eggs to adults were(11.19±1.23)℃,(12.57±1.26)℃,(12.62±1.14)℃,(12.07±1.19)℃ and 69.08±6.63,85.01±11.07, 56.60 ±5.89,198. 89±20.94 day degrees, respectively. A lineamodel can be used to simulate the relationship and the duration of the different developmental stages and temperatures. The fecundity of the adults under 17 ℃ to 33 ℃ were tested in the laboratory. The rate of oviposition daily became maximum at 25 ℃,which was much higher than other temperatures.
