摘要
本文研究了3种营养成分不同含量的饲料对美洲大蠊若虫生长和发育的影响,结果表明,美洲大蠊若虫孵化后取食饲料2120天,其平均体重为（35.95±0.68）mg/头,较取食饲料1、饲料3的美洲大蠊若虫的体重高;美洲大蠊若虫对饲料3的日平均取食量（2.58±0.48）mg/头较饲料2的日平均取食量（1.99±0.83）mg/头多,但美洲大蠊若虫从饲料2、饲料3中日摄食的蛋白质和脂类间无差异（P〉0.05）;美洲大蠊若虫对饲料2的利用率（95.67±1.32）%和食物转化效率（14.22±6.48）%高,与对饲料1、饲料3的利用率、食物转化效率间存在差异。美洲大蠊若虫取食饲料2较取食其他2种饲料更有利于其生长发育。
The effects of three feedstuffs on the development of American cockroach nymph were studied. The results showed that body weight of the nymph fed on the second feedstuff was higher than those fed on the other two feedstuffs. One hundred and twenty days after hatching, the average body weight of nymph fed on the second feedstuff was （35.95 ± 0.68） mg per nymph. The American cockroach nymph daily feeding amount was （2.58 ± 0.48） mg per nymph on the third feedstuff and was （1.99 ± 0.83） mg per nymph on the second feedstuff. The daily nutritional ingredient of American cockroach nymph fed on the second feedstuff and the third feedstuff was not different between protein and fat （P 〉 0.05）. The efficiency of forage utilization （95.67 ± 1.32） % and forage conversion （ 14.22 ± 6.48） % of the nymph fed on the second feedstuff were higher than those fed on the other feedstuffs, and there was different among the three feedstuffs. Thus, the second feedstuff was better than the other two feedstuffs in improving the development of American cockroach nymph.
