Also, role of stablimenta in efficiency of capturing prey was discussed by comparing web parameters and number of intercepted insects in decorated and non-decorated webs. For the study, 236 randomly selected webs of A. trifasciata were observed in the rice fields around the cities of Sheikhupura and Lahore, Punjab, Pakistan. In the adult

By and large, macroinvertebrate fauna was lower in the soils studied as compared to other tropical and subtropical regions reported elsewhere. Therefore, keeping in view the key role of soil invertebrates i...
