Infection of Meloidogyne javanica by Paecilomyces lilacinus

The in vitro interaction of Paecilomyces lilacinus strain 251 with eggs, 3r d and 4th stage juveniles and adult females of Meloidogyne javanica was stu died. Eggs of all stages, including those containing unhatched juveniles, w ere infected by P. lilacinus. Infection of eggs occurred following flatteni ng of hyphae to the egg surface and formation of appressoria. Sometimes the se occurred within extensive networks of hyphae of the egg surface. Hyphae later grew out of the egg to continue growing or form conidiophores. Third and 4th stage juveniles and adult females were readily infected, with hypha e and conidiophores penetrating the body wall.
