摘　　要：在室内恒温条件下,观察不同温度对香蕉褐足角胸叶甲生长发育的影响,并用直线回归法测得产卵前期、卵、1～4龄幼虫、老熟幼虫感应期、蛹和全世代的发育起点温度分别为14.83(±1.17)℃、14.09(±0.97)℃、14.74(±0.47)℃、17.74(±1.05)℃、15.32(±0.73)℃、14.55(±0.79)℃;有效积温分别为158.17(±18.47)d·℃、81.00(±7.34)d·℃、437.88(±18.24)d·℃、65.70(±8.55)d·℃、74.21(±5.62)d·℃、870.95(±65.63)d·℃。香蕉褐足角胸叶甲的各虫态和全世代发育历期均随温度的升高而缩短,在测定的温度范围内,全世代发育历期与温度的关系符合指数函数y=1536.6e-0.1121x。根据有效积温法则预测该虫在南宁市理论发生代数为3.1～4.1代/年,这与实际发生情况基本相符合。The effect of temperature on the growth and development of Basilepta fulvipes Motschulsky was studied. Linear regression indicated that the threshold temperatures for preoviposition, eggs, 1-4 instar larvae, old familiar larvae and pupae, and from preoviposition to pupation were 14.83 （±1.17）℃, 14.09 （±0.97）℃, 14.74 （±0.47）℃, 17.74（±1.05 ）℃, 15.32 （±0.73）℃, 14.55 （±0.79）℃ ,respectively. The effective accumulated temperature for the above stages were 158.17（±18.47）d·℃, 81.00（±7.34）d·℃, 437.88（±18.24）d·℃, 65.70（±8.55） d ·℃, 74.21 （±5.62）d·℃,870.95 （±65.63）d·℃, respectively. The developmental duration of each developmental stage, and froln preoviposition to pupation, decreased with increased temperature. The developmental duration of a singlegeneration was fitted with the index function： y=1536.6e-0.1121x. According to the effective accumulative temperature law, we predicted that this pest would have 3.1- 4.1 generations annually in Nanning,whieh is in accordance with field observations.
