Effect of Humidity on Life of Experimental Lasioderma serricorne (Fabricius)
-
摘要: 在(32±1)℃,光周期为14 L:10 D条件下,通过组建烟草甲实验种群两性生命表的方法,探讨了不同湿度对烟草甲Lasioderma serricorne(Fabricius)生长发育和繁殖的影响。结果表明:在50% RH和90% RH条件下,烟草甲未能完成一个世代的发育,90% RH条件下幼虫在1龄全部死亡,50% RH条件下幼虫在2龄全部死亡;而在60% RH、70% RH和80% RH条件下烟草甲均可完成世代发育。卵期长短除70% RH和90% RH外,其余湿度条件下均无明显差异。幼虫发育期在60% RH和70% RH条件下无明显差异;而在80% RH下1、2、3龄发育时期均为最低,分别为8.08 d、6.82 d和7.05 d;60% RH条件下,烟草甲雌成虫寿命最长为25.84 d,80% RH下雄成虫寿命最长为15.25 d;雌成虫产卵前期(2.55 d)、总产卵前期(58.41 d)和产卵期(7.00 d)在80% RH条件下均为最短,60% RH和70% RH条件下无显著差异。60% RH、70% RH和80% RH等3个湿度条件下,繁殖力、特定年龄-龄期阶段的生命期望值(exj)、特定年龄-龄期阶段的生殖价(Vxj)有显著性差异,其中在60% RH条件下均为最大;随着湿度的增加,净增殖率R0逐渐减小分别为37.69、30.65、15.02,内禀增长率r和周限增长率λ分别为0.05、0.05、0.04和1.05、1.05、1.04,均无显著差异;60% RH和70% RH条件下的世代周期T(分别为72.68 d和72.79 d)无显著差异,但均显著长于80% RH(62.80 d);对烟草甲种群进行预测,结果表明60% RH、70% RH和80% RH等3个湿度条件下烟草甲种群最低虫口数分别出现在60、50、38 d,之后种群数量开始剧增,建议在此期之前应采取防治措施。Abstract: Effects of environmental humidity on the growth, reproduction and survival of the Lasioderma serricorne population in laboratory were studied. Varied relative humidity, i. e., (50±5)%, (60±5)%, (70±5)%, (80±5)% and (90±5)% RH, at (32±1)℃ with a photoperiod of 14-h-L:10-h-D were applied. The results showed that (1) L. serricorne failed to completely develop a single generation under 50% or 90% RH-the first generation larvae died at 90% and the second instar perished at 50%, but it could under the other humidified conditions in the test; (2) there were no significant variations in the egg development time under the tested RHs, except 70% and 90%; (3) the larval developments were similar under 60% and 70% RH, however, at 80% RH, the duration of the 1st stage (i. e., 8.08 d), 2nd stage (i. e., 6.82 d), and 3rd stage (i. e., 7.05 d) were significantly shorter than the others; (4) the longest life span of 25.84 d was found in female adults at 60% RH, and 15.25 d in males at 80% RH; (5) the shortest pre-oviposition period of 2.55 d, the total pre-oviposition period of 58.41 d and the oviposition period of 7.00 d were found when the RH was 80%, but no significant difference at 60% or 70%; (6) there were significant differences on the fecundity, age-stage life expectancy (exj), and age-stage specific reproductive value (Vxj) of the insects reared under 60%, 70% or 80%, and they peaked at 60% RH; (7) the net reproduction rates (R0) decreased from 37.69 at 60% to 30.65 at 70% and 15.02 at 80% RH, whereas, the intrinsic rates of increase (r) and finite rates of increase (λ) showed no significant differences as the RH was altered; (8) there were no significant differences on the generation times (T) of 72.68 d at 60% and 72.79 d at 70% RH, but they were significantly longer than 62.80 d at 80%; and (9) the lowest larval counts were found on the 60th d under 60%, the 50th d under 70% and the 38th d under 80% RH, and escalated significantly afterward suggesting an optimal time for the insect control.
