德国小蠊成、幼虫自动分离器的研制

The development of the automatic apparatus for separating the imagoes and larvae of Blattela germanica

目的将成虫和幼虫在自然状态下自动分离。方法将附着于锯齿形纸片上的德国小蠊成、幼虫连同纸片一起放入分离器一侧的缸中,另一侧缸中放入食物和水进行引诱。结果第4天蜚蠊的成、幼虫分离率在50%以上,第6天可达90%以上。结论自然状态下,该分离器依靠食物和水的引诱作用,能够将德国小蠊成、幼虫自动分离,所获幼虫龄期基本一致。

Objective To separate automatically the imagoes and larvae of Blattela germanica. Methods Put the Blattela germanica＇ s imagoes and larvae which attach to the zigzag slips into one side of the vat of separate apparatus, together with the slips, and in another side the vat, put food and water to make a temptation. Results On the fourth day the separative rate of germanica＇s imagoes and larvae was above 50 %, above 90 % on the sixth day. Conclusion Depending on temptation of food and water, the separate apparatus can separate the Blattela gerrnanica＇ s imagoes and larvae automatically, and the ages of acquired larvae are uniform on the whole.
