摘要
对本地常见室内蜚蠊,即黑胸大蠊、美洲大蠊及德国小蠊卵鞘寄生蜂鉴定,发现三类寄生蜂,主要种类为啮小蜂。进行单个培养,每枚卵鞘内羽化出3～201头啮小蜂;另两类寄生蜂,每枚卵鞘只能发育1头。捕捉278枚三种蜚蠊卵鞘,黑胸大蠊249枚(89.57%),为优势种;美洲大蠊有25枚(8.99%);德国小蠊仅4枚(1.44%)。1987年4～7月,捕捉161枚黑胸大蠊卵鞘,寄生啮小蜂的卵鞘数为105枚,寄生率为42.17%,最高月份为5月,寄生率为53.93%;最低为6月,寄生率为17.03%。试验9种人体肠道细菌培养基,啮小蜂可在其中三种培养基内产卵,并发育为成虫。这些培养基内均不含任何昆虫卵。
By appraisal of the common local house cockroaches, i. e. , the Periplaneta Fuliginosa, the Periplaneta Americana, and the Blattella Germanica, three kinds of parasitic wasps were found out, of which the tetrastichodes is the main kind. When these oothecae were cultivated separately, it was found that 3～201 heads of tetrastichodes emerged from each of the oothecae, whereas only one head emerged from each of two others. It was also discovered that when 278 heads of cockroach oothecae were caught, 249 of them belonged to the Periplaneta Fuliginosa (89. 5%), the predominant species; 25 of them belonged to the Periplaneta Americana(8.99%): and 4 of them belonged to the Blattella Germanica (1.44%). From April to July in 1987, 161 heads of oothecae of the Periplaneta Fulignosa were collected and the parasitic wasp held 105 oothecae (42.17%). The parasitic wasp reached its highest number of oothecae in May(53.93%) whereas the lowest in June (17.03%). Next. nine kinds of culture media were tested which were used for the cultivating of human intestinal bacteria, and it appeared that the tetrastichodes oviposited and developed from an egg to an imago in three media in which contained no insect eggs at all.
