作者用啮小蜂对烟色大蠊,日本大蠊、美洲大蠊和德国小蠊4种蜚蠊卵荚进行接蜂试验。结果表明:除德国小蠊卵荚外,其它8种卵荚接蜂成功,寄生率分别为45.08％、53.06％和64.04％,羽化率分别为11.69％、28.57％和47.19％,在卵荚内平均发育期分别为64.63、66.79和48.38天。美洲大蠊卵荚寄生率高,羽化出雌蜂数较多,发育历期短,容易采集。因此,作者认为实验窒繁殖寄生啮小蜂应首选美洲大蠊。
The authors tested the pick-and-place test of four species of cockroach egg cocks of the cockroach, the Japanese cockroach, the American cockroach and the German cockroach with the bee-pollinating bee. The results showed that except for the pod of Blattella germanica, the other 8 kinds of oak pods were successfully parasitized with the rates of 45.08%, 53.06% and 64.04%, respectively, with the emergence rates of 11.69%, 28.57% and 47.19%, respectively. The average developmental period was 64.63, 66.79 and 48.38 days respectively. American cockroach egg pod parasitic rate is high, emergence of more females, developmental period is short, easy to collect. Therefore, the authors believe that the experimental choke the parasitic nematodes beetle preferred American cockroach.
