Population sizes can comprise millions of individuals and in a cave there can be one to 15 bugs per bat. It was estimated that adult African bat bugs feed approximately once per week thus withdrawing 1-28 microlitre blood per day per bat.〔K. Reinhardt, R. Naylor, M. Siva-Jothy, Estimating the mean abundance and feeding rate of a temporal ectoparasite in the wild: Afrocimex constrictus (Heteroptera: Cimicidae). International Journal for Parasitology, Vol 37, pp. 937-942, July 2007〕 As in many other cimicids, ''Afrocimex constrictus'' reproduce through traumatic insemination. During mating, the male pierces the female's abdomen with his genitals, and ejaculates into her body cavity, into a special organ called the spermalege. While females do have external genitalia, they are used for egg laying but not for mating.〔R. L. Usinger, Monograph of the Cimicidae (Hemiptera-Heteroptera). The Thomas Say Foundation Vol 7, Entomological Society of America, 1966〕 ''Afrocimex constrictus'' males also pierce and inseminate other males. Male-male stabbings were originally probably harmful to males and so it was speculated that male-male stabbings were the reason that ''Afrocimex constrictus'' males have - like females - evolved a spermalege. The male spermalege looks similar but not identical to the typical female spermalege and males receive fewer stabbings than females.〔K. Reinhardt, E. Harney, R. Naylor, M. Siva-Jothy, Female-limited polymorphism in the copulatory organ of a traumatically inseminating insect. American Naturalist, Vol 170, pp. 931-935, December 2007〕 In one cave around 80% of the females were found to mimic the male version of the spermalege and such females receive fewer stabbings from males than females that have the original spermalege type.〔 The species also had a brief appearance in fiction. In Bernard Werber's novel ''Le jour de Formis'' (no English edition) from 1997, the mating habits of '' A. constrictus'' are being employed in the torture chambers of the ants. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Afrocimex constrictus」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
