Cyst nematode life cycle. Diagram showing the stages in the life cycle of a cyst nematode,a form of nematode worm that is a parasite on crop roots. Examples include the soybean cyst nematode (SCN). The secondary juvenile forms emerge from the cyst (centre left) and attach to a plant root (upper left). Clockwise,the cycle continues as the female form (red) swells in size as it feeds). At lower centre,the male form (blue,also at centre) has detached and has moved to find and fertilise a female worm. The fertilised female worm produces the eggs within itself,dies and forms the cyst (lower left) that restarts the whole cycle | |
