Fig 1.
Parasitism by Phanerochaete chrysosporium strain B-22 on the eggs of Meloidogyne incognita.
(a) Spores germinated, and short hyphae developed around the egg; (b) hyphae penetrated across the eggshell; (c) the eggshell was dissolved; (d) control: healthy, intact eggs. All observations were made under 40× magnification.
Fig 2.
Parasitism of Phanerochaete chrysosporium strain B-22 on the second-stage juveniles (J2) of Meloidogyne incognita.
(a) Spores came into contact with M. incognita J2 (20× magnification); (b) spores geminated and hyphae grew out from the bodies of M. incognita J2 (40× magnification); (c) more mycelium was produced from the bodies of M. incognita J2 (20× magnification); (d) the cuticles of M. incognita J2 were bent and shrunken (40× magnification); (e) M. incognita J2 were parasitized by P. chrysosporium strain B-22 hyphae (20× magnification). (f) Control: healthy M. incognita J2 (20× magnification).
Fig 3.
Parasitism of Phanerochaete chrysosporium strain B-22 on Meloidogyne incognita adult females.
(a) Spores geminated, and the contents of M. incognita adult female bodies leaked out; (b) dense hyphae crossed M. incognita adult female bodies, which were partly dissolved. (c) Control: healthy adult female. All observations were made under 10× magnification.
