Variation in Life Cycle of Meloidogyne Incognita in Different Months in Indian Condition

Anamika ^[25] | Sobita Simon

Abstract: The life cycle of M. incognita in tomato and brinjal seedlings during different months at different temperature was recorded. The life cycle of M. incognita seems to be related with temperature. The most ideal temperature for the development of M. incognita seems to be between 20- 250 C. It was observed that inoculated seedlings raised during the month of June showed 2nd stage juveniles started invading within 40- 48 hours after inoculation. Maximum penetration of J2 was observed on the 5th day after inoculation. The life cycle of the nematode was completed within 16 days during the month of June i. e. from 2nd stage juveniles to 2nd stage juveniles. The life cycle studies in June, July and August also showed similar trend whereas in September it was reduced by one day and in October it was extended by two days. During the month of November the life cycle was completed in 25 days for completion of one generation. During the month of December and January although seedlings were infected by second stage juveniles but further no development occurred due to extreme low temperature.
