Abstract

Margosan-O®, a commercial neem-based insecticide, incorporated into an artificial diet prolonged the development of larvae of Spodoptera littoralis Boisduval. It also affected the rate of adult emergence at the end of pupation. Larvae treated during one stadium continued to show the effects of their previous exposure. The susceptibility to Margosan-O was more pronounced when larvae ate the diets containing Margosan-O for the first time during the fifth or sixth instar. The results indicate that Margosan-O has an activity similar to that of other neem-seed extracts. In the course of this work morphological anomalies were also recorded. The most striking was the appearance of black stripes on the abdominal tergites of the fifth and sixth instar larvae fed on diets containing 0.01, 0.05 or 0.1% of Margosan-O.

Résumé

Un insecticide commercial à base d'azadirachtine (Margosan-O®), incorporé à la nourriture artificielle, a prolongé la durée de développement des larves de Spodoptera littoralis Boisduval. Il a également affecté le nombre d'émergence d'adulte à la fin du stade nymphale. Les larves traitées pendant un stade donnée continuaient à manifester les effets de leur exposition au substrat. La sensibilité du Margosan-O était plus importante lorsque les larves se nourrissaient d'un substrat contenant Margosan-O au cours du cinquième et sixième stade. Les résultats montrent que le Margosan-O a la même activité que d'autres extraits à base de neem. Cet insecticide provoque également chez Spodoptera littoralis des anomalies morphologiques au cours des stades de développement; des bandes noires apparaissent sur les tergites abdominales lorsque les larves du cinquième et du sixième stade se nourrissent d'un substrat contenant 0.01, 0.05, ou 0.1% de Margosan-O.
