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 different temperature on the growth and development of Banana beetles was observed under the condition of constant temperature indoors. The ovarian early-oviposition, eggs, 1st to 4th instar larvae, mature larvae induction period, pupae and whole generation The developmental threshold temperatures were 14.83 ± 1.97 ℃, 14.09 ± 0.47 ℃, 14.74 ± 0.47 ℃, 17.74 ± 1.05 ℃, 15.32 ± 0.73 ℃, 14.55 ± 0.79 ℃, respectively. The effective accumulated temperature Respectively, which 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 · ° C. The banana and full-length developmental durations of Banana stegosaurus were both shortened with the increase of temperature. The relationship between the developmental period and the temperature of all generations in the measured temperature range was in accordance with the exponential function y = 1536.6e- 0.1121x. According to the law of effective accumulated temperature, it is predicted that the theoretical generational instability of the insect in Nanning City is from 3.1 to 4.1 generations / year, which is basically consistent with the actual occurrence.
