Bonafonte, P. 1979 Structure du sperme et migration des spermatozoides dans les voies genitales femelles de Chrysomphalus ficus. [Sperm structure and migration of spermatozoids in female genital ducts of Chrysomphalus ficus (Homoptera, Diaspididae)].. Annales de la Société Entomologique de France 15: 505-512.
Notes: Spermatozoa of C. ficus, are emitted in the female genital ducts in the form of sperm bundles. Each sperm bundle is formed by 32 spermatozoa, each surrounded by a spiral of 90-100 microtubules. After fertilization the bundles or the individualized spermatozoa, migrating from the spermatheca through the oviduct and ovarian canal, enter a specialized cell situated in the pedicel of the ovariole: the Krassilstchick's cell or vestibular cell. This cell is probably a nutritive cell for the spermatozoa, permitting them to await the maturation of the oocyte.
