摘要
【目的】筛选能够提高黄粉虫Tenebrio molitor Linnaeus成虫繁殖能力的蔬菜种类,降低养殖成本,提高产量,增加利润。【方法】以萝卜、马铃薯、白菜、胡萝卜、蕹菜和黄瓜6种蔬菜作为辅助饲料,研究添加不同蔬菜对黄粉虫成虫寿命、繁殖和生命表参数的影响。【结果】黄粉虫成虫的产卵期和寿命以添加黄瓜和胡萝卜的为最长,但二者的内禀增长率(rm)和周限增长率(λ)明显最低,种群倍增时间(t)显著加长。添加萝卜、马铃薯、白菜和胡萝卜的黄粉虫其总产卵量最多,但添加后者的日均卵量却显著少于前三者。添加萝卜、马铃薯、白菜和蕹菜的黄粉虫在世代平均历期(T)、rm、t和λ4个参数上均没有显著差异,但添加蕹菜的净增殖率(R0)和产卵量却显著少于前三者,雄虫比例在所有6种处理中最高。【结论】萝卜、马铃薯和白菜3种蔬菜有助于提高黄粉虫成虫的繁殖力和种群增长率。
[Objectives] To identify new food plants that can improve the reproductive capacity of captive-raised Tenebrio molitor, reduce the energy consumption and cost of breeding this species in captivity, and increase production and profits.[Methods] Six vegetable species, Raphanus sativus, Solanum tuberosum, Brassica chinensis, Daucus carota, Ipomoea aquatica, and Cucumis sativus, were assessed as alternative foods for T. molitor.[Results] The longevity, reproduction, and life table parameters of T. molitor adults raised on these different plants was quantified and compared. Although adults fed on D. carota and C. sativus had the greatest longevity and longest oviposition period, their intrinsic(rm) and finite rate of increase(λ) were the lowest, and the doubling time of the population(t) was significantly longer than that of adults fed on other food plants. The total fecundity of adults fed on R. sativus, S. tuberosum, B. chinensis, and D. carota was significantly higher than that of those fed on other food plants, however, the daily fecundity of adults fed on D. carota was significantly lower than that of those fed on the other food plants. There were no significant differences in the mean generation time(T), rm, t, and λ of adults fed on R. sativus, S. tuberosum, B. chinensis, and I. aquatica;however, the net reproductive rate(R0) and fecundity of those fed on I. aquatica was significantly lower than those fed on the other food plants and the proportion of male offspring was the highest among all six treatments.[Conclusion] Feeding T. molitor on R. sativus, S. tuberosum, and B. chinensis can improve the reproductive capacity and population growth rate of this insect.
