Tatera indica, the Indian gerbil rat trapped during different growth stages of wheat crop, revealed that maximum mature gerbils (80-100%) were trapped during later growth stages (panicle initiationpreharvest+ lean period). While, 25 and 50% pregnant ones as well as 100 and 75% cyclic gerbils were collected during dough and preharvest stages, respectively. The weight of ovaries (13.00-19.00 mg/ 100 gbw), number and diameter of various follicles such as primordial (13.00-16.75; 19.57-19.98 μm), primary (6.50-7.33; 93.12-96.07 μm), secondary (2.75-3.67; 204.42-216.95 μm), pre-antral (2.75-3.50; 277.63-332.57 μm), antral (3.25-3.67; 474.44-499.98 μm), atretic (3.00-3.50; 211.49-247.33 μm) and corpus luteum (3.50- 5.50; 622.24-629.76 μm) were significantly more during later growth stages i.e. dough, preharvest stages and lean period. The sperm motility (89.50-89.67%), viability (92.50-92.67%) and count (119.67-131.75 millions/ ml) was significantly more during dough and preharvest stages. The diameter of seminiferous tubules (203.68- 229.44 μm), number of spermatogonia (16.67-17.50), elongating spermatids (85.67-88.50) and elongated spermatids (81.00- 89.50) were significantly more during panicle initiation, dough and preharvest stages. Thus, control operations of T. indica should be done during tillering/ panicle initiation stage before the initiation of their peak breeding activity during dough/preharvest stages.
