| Summary: | WOThers of the termite, Coptotermes curvignathus (IsofJtera: Rhinotermitidae), apestofmany tree crops including
fruit and plantation trees, were inocttlated with the ento mopathogenic fungus, Metarh izium an isopliae byexfJosing
the termite to viable conidia in a pet-Ii dish. The ontogeny of the fungus was followed histologically. Conidia which
landed on the cuticle germinated within 24 h. The germ tube penetrated the cuticle and the hyphae subsequently
invaded the tissues in the following order:fat body, muscles, neural, gut epithelial cells and gizzard. Infected termites
died between 36- 48 h post-inoculation. Complete colonization of the tennite, however was not histologically evident
until 72 h post-inoculation. At this stage, all parts of the insect '5 internal organs were infected. At 100 h, whitish
mycelia began to emerge from the cuticle. Compacted masses of conidiophore1J'fOducing-green conidia were formed
120 h post-inoculation. |
