中华微刺盲蝽捕食菜青虫卵试验初报

Preliminary Study on Campylomma chinensis Preying on Eggs of Pieris rapae

研究结果表明:中华微刺盲蝽可捕食菜青虫卵,随着虫龄的增长,日捕食量逐渐增大.30%～60%菜青虫卵被刺吸,但卵汁并没有被完全吸干.在遮荫条件下盲蝽取食卵量增加.温度在25～30℃中华微刺盲蝽对菜青虫卵的取食量最大,相互干扰会降低中华微刺盲蝽对菜青虫卵的寻找效应.

The experiment of feeding C. chinensis on eggs of P. rapae was carried out. The results showed that the number of eggs ingested daily by C. chinensis increased gradually with the growth of the instar stage. Among 30 % -60 % ingested eggs, the egg albumin was not sucked completely dry. Under shadow condition C. chinensis could ingested the eggs more, and at 25-30℃ it could ingested the eggs most. But mutual interference could decrease the efficiency of C. chinensis searching for the eggs of P. rapae.
