PARASITISM OF MELOIDOGYNE INCOGNITA EGGS BY NATIVE FUNGI OF ASSAMUday Kurulkar and Bhahesh Bhagawati
In the current investigation, four fungi viz., Paecilomyces niphetodes, Acremonium falciforme, Fusarium oxysporium, and F. solani were capable of parasitizing Meloidogyne incognita eggs. The high percentage of egg parasitism was recorded by P. niphetodes. Microscopic examinations showed that the hyphae of P. niphetode, A. falcifrome, F. oxysporum and F. solani were closely attached to the egg surface of the parasitized eggs, made perforations, penetrated, ramified, and completely fed upon the internal content of the eggs. The parasitization of the second stage juvenile that emerged from the eggs by P. niphetodes and A. falciforme was seen. Whereas, A. falcifrome, F. oxysporum, and F. solani established as dormant spores inside or outside of M. incognita eggs.
