Abstract

The pathology of the nuclear polyhedrosis virus from Spodoptera littoralis against Kalotermes flavicollis was confirmed under light microscope. Sections of infected termites showed a comprehensive viral infection. Nuclei of cells of the foregut, cardiac valve, pyloric valve, hindgut, gut musculature, fat body, nerve tissue, muscle, oviduct, pedicel of he ovariole, calyx, accessory glands, wing buds in termite reproductive nymphs, and to a lesser degree, the tracheal matrix, malpighian tubules and hypodermis, were susceptible to the virus. Infection to midgut was generally limited. However, when the termites were heavily infected, the midgut epithelial cells sloughed off into the lumen, and became hypertrophied and granular.

Résumé

La pathologie du Spodoptera littoralis viruse polyhedrose nucléaire (VPN) dans les termités, Kalotermes flavicollis à été confirmé par le microscope ordinaire. Des sections des termités infectles montrent une infection virale trés comprehensible. Les noyaux des célulles de I'intestin antérieor, de la valve cardique et pylorique, de I'intestin posterieur, musculaturè intestinale, du corps gras, du tissue nerveux, du muscle, de l'oviducté, le pedicle de l'ovariole, le calyx, les accessoire glandes et de l'aile des bourgeons des nymphes reproductrices du termités, et à moindre degré, le traché de la gangue, des tubes malpighiens et de l'hypoderme sont susceptible à 1'invasion par le viruse. D'autre part, les infections de l'intestin moyen est géneralement bien limitée, quand l'infection des termités est sévere les céllules épithéliales de l'intestin se détache dans la cavité intestinale, est devien hypertrophié et granulaire.
