Abstract

Glyphidrilus annandalei Michaelson exhibits a pronounced breeding period extending from September to November. Breeding individuals achieve their maximum frequency in September, when 50 per cent of the whole population was with fully developed clitellum. Studies on the physical and chemical conditions of the habitat revealed that breeding in this worm depends the monsoon of the area creating optimum conditions for the life and activities of the organism.
