Abstract

Studies were carried out to elucidate the parental (vertical) transmission of Nosema marucae Odindo and Jura, in infected females of Chilo partellus Swinhoe. Results indicated that only infected females of C. partellus could pass infection to the offspring. Infection also lowered both the total number of eggs laid per female and egg hatchability- Some adults which developed from the sublethally infected fifth instar larvae of C. partellus had deformed wings while some pharate adults failed to free themselves from the pupal cases. The significance of these deformities to the ecological survival of C. partellus is discussed.

Résumé

Les études ont été conduites pour déterminer la transmission verticale de Nosema marucae Odindo et Jura, dans les femelles infecteés de Chilo partellus Swinhoe. Les résultats ont montré que seules les femelles de C. partellus infectees peuvent transmettre l'infection aux progénitures. L'infection reduit aussi bien le nombre total des pontes par femelle que leur éclosion. Certains adultes issus des larves du 5éme stade soumises aux doses subléthales avaient des ailes déformées, tandis que d'autres étaient incapables de se détacher de la chyrsalide. L'importance de ces diformités sur la survie écologique de C. partellus est discutée.
