Nevertheless, LIPA and CHMÎELEWSKI (1966) very frequently observed the hatching of eggs and the development of various stages inside the body of dead females of Caloglyphus sp. Table 5.

Females of Caloglyphus and Acotyledon did not receive enough sperm in a 1-2-day exposure period to male to achieve their full egg-laying potential. Moreover, a small number of eggs was observed in the case of the isolation of female after 1-2 day exposured to males as compared with the data in Table 2.
