摘要:

目的 研究美洲大蠊取食过的饲料对德国小蠊摄食行为的影响,从食源方面探讨德国小蠊逐步取代美洲大蠊的原因。方法 采用单一摄食法、形状选择摄食法和Y型嗅觉仪实验方法,观察德国小蠊的摄食情况。结果 单一摄食实验第2~12天,德国小蠊对美洲大蠊取食过的饲料(饵料B)摄食量是新鲜饲料(饵料A)的33.48倍,差异有统计学意义(P<0.05);实验第14~26天,德国小蠊对两种饵料的摄食量差异无统计学意义(P>0.05);而第28~36天,德国小蠊对饵料A的摄食量是饵料B的3.02倍,差异有统计学意义(P<0.05)。Y型嗅觉仪实验结果显示德国小蠊对饵料B的摄食量呈正趋向性。饵料形状对德国小蠊的摄食量无影响(P>0.05)。结论 德国小蠊对美洲大蠊摄食食源的高度适应性,增加了德国小蠊的生存机会。

Abstract:

Objective Examine the effect of used feed by Periplaneta americana on feeding behavior of Blattella germanica to explore causes of B. germanica displacing P. americana. Methods Feeding amount, shape and Y-tube olfactometer experiments. Results Blattella germanica prefered P. americana used feed(feed B), 33.48 times of fresh mouse feed(feed A)(P<0.05)through 2-12 d by feeding amount experiment; During 14-26 d,feeding amount of two feeds were similar(P>0.05); while during 28-36 d, Blattella germanica preferred feed A 3.02 times more than feed B (P<0.05). In Y-tube lactometer experiment, all B. germanica selected the feed B. And the shape experiment indicated that the shape didn't affect the feed amount of B. germanica(P>0.05). Conclusion The quick adaption of B. germanica to P. americana used feed improve their chance of survival.
