摘要:

目的 筛选美洲大蠊若虫饲料的优化配方。方法 采用L9(34)设计方法,研究小麦粉、奶粉、干酵母粉3种物质不同配比对美洲大蠊若虫生长发育的影响。结果 实验结果表明,若虫饲养120 d后,取食配方S5的若虫体长增量(19.21 mm/只)、日取食量(25.94 mg/只)、体重(532.5 mg/只)及若虫对饲料的利用率(96.69%)均高于取食其他配方饲料的若虫。结论 美洲大蠊若虫最佳的饲料配方为小麦粉∶奶粉∶干酵母粉=2∶4∶1。干酵母粉是美洲大蠊若虫体长增量的关键因子,有利于若虫的生长。

Abstract:

Objective To identify the optimum feed formula for nymphs of Periplaneta americana. Methods The L9 (34) design was employed to analyze the impact of wheat flour, milk powder and dry yeast powder of different proportions on the nymphal growth and development of P. americana. Results Experimental results showed that after 120 d of feeding, the body length increment (19.21 mm/nymph), daily food consumption (25.94 mg/nymph), weight (532.5 mg/nymph) and consumption rate (96.69%) of nymphs fed with formula S5 were higher than the values in those fed with other feed. Conclusion The optimum formula of feed for nymphs of P. americana was wheat flour: milk powder: dry yeast flour=2∶4∶1. Dry yeast powder was the key factor of nymphal body length increment for P. americana, which was conducive to the growth of nymphs.
