The data on various reproductive behaviours of 1000 buffaloes in 15 randomly selected farms of Hyderabad region during July 1997-June 1999 were collected and analysed. The highest percentage (48.73) of calving frequency in summer and the lowest in spring (8.19) was observed. During summer expulsion of fetal membrane took more hours but few hours in autumn, same was true in first postpartum estrus, which took prolonged non significant days in spring and Summer (100 19-102.73 days). Uterus involution period followed the same pattern as in calving frequency i.e., peak in summer and low in spring. The service period of buffalo ranged between 90.39-149.09 days, where it took maximum days in summer and minimum in autumn.

The study of Acridoidea is one of the significant work  for the aim of insects systematic process. This Order Orthoptera comprised of insects with paurometabolus type metamorphosis,including grasshoppers,Crickts and locusts.During present work five species and subspecies of the genus  Acrotylus were observed namely Acrotylus humbertianus (Saussure), A. insubricus insubricus (Scopoli) A. patruelis(Herrich-Schaffer) A. longipes longipes (Charpentier) and A. longipes subfasciatus . The spermatheca is an organ playing a key role in insect reproduction, it allowing the  storage of spermatozoa and making them available when it needed, More ever there is information about the genitalia of these grasshoppers .Where as some information is present in the literature on morphology of species of the genus Acrotylus (Fieber).At present my studies expose the diagnostic characters of  epiphallus and Spermatheca that have useful value for the purpose of accurate identification.  Epiphallus with  moderately wide bridge, narrow ancorae and bilobate lophi. Spermatheca is a coiled duct of ectodermal origion. It is of  varying sizes and shapes. The spermatheca well dilates to form a sac like structure, for storing  the spermatozoa which enter during  copulation. Where as this study will provide  the beneficial support for new research workers in future.
