Abstract
Investigations have been made to evaluate the development of Spodoptera littoralis as affected by feeding on a standard artificial diet containing powder of some plant species known to be resistant to the infestation of this insect. Trials were also made to find out whether the effect of these plants facilitate the potency of Bacillus thuringiensis var entomocidus HD-635 vs. the target insect. The results revealed that powders of pomegranate peel, guava leaves and lemon grass, greatly affected the insect development in terms of larval duration, larval and pupal weights, deformities in pupae and moths, percentage of emergence, egg production and hatching. This may be correlated to the chemical constituents of these plants. A marked increase was observed in the potency of B. thuringiensis endotoxin preparation vs. S. littoralis when combined with some of the tested powdered plants or its extracts but in varying degrees. Les investigations ont fait pour evoluer le development de Spodoptera littoralis qui est a effecté par la nouriture sur un olimentation artificiel standard contient poudre de quelques spèces de plantes qui sont convues comme resistente contre l'invasion de l'insecte.Les jugements sont faites encore pour trouver si l'effet de ses plantes facilitent la puissance de Bacillus thuringiensis var. entomocidus HD-635 contre l'insect.Les resultats réveloient que les poudres de granade epluché, les feuilles de guava et l'herbe de citran effectoient grandement le development de l'insecte dans le period de larve, le poids de larve et de numph, le diformité du numphs de mites, le pourcentage de l'emergence, la production des oeufs et ses éclosions. Ces resultats peut être correspondrent avec les constituents chimiques des ces plantes. Une gronde augmentation etait observé dans la priussance de l'endotoxin preparer par B. thuringiensis contre S. littoralis quand il est réuni avec quelque plantes éxaminer ou leurs extraits mois dans divers degré.Keywords
