Abstract

Sun-dried guava (Psidium guajava L.) and eucalyptus (Eucalyptus globulus L.) leaves were evaluated as repellent and toxic materials against the rice weevil, Sitophilus oryzae L., and the granary weevil, Sitophilus granarius L. under laboratory conditions. LC50 values of sun-dried guava and eucalyptus leaves admixed with rice grains against S. oryzae were 2.251 and 4.140g leaves/100g rice grains, respectively, while they were 2.278 and 4.857 g leaves/100 g rice grains in the case of S. granarius, respectively. Guava leaves were more toxic for both species than eucalyptus leaves. Eucalyptus leaves were more repellent than guava leaves.

Both test materials at 15 g/100 g depressed the progeny development of the test insects.

Résumé

Les fauiles morqueés de goyave (Psiduim guajava L.) et de (Eucalyptus globulus) séché an soleil étaient évalués comme des matiéres répulsives et toxiques contre le charancon du riz Sitophilus oryzae et le charancon du grenier Sitophilus granarius sous les conditions du laboratoire.

Le LC50 des feuilles de goyave et de eucalyptes séché an soleil melangevient avec les groeins du riz contre S. oryzae etaiant 2.251 et 4.140 g feuilles/100 g grains due riz, respectivement. Il paraît que les feiulles de goyave etaient plus toxiques pour les deux espèces que les feuilles de Eucalyptus. Les resultats montrent encore que l'acturté répulsif des feuilles de eucalyptus étaient plus que celles des feuilles de goyave.

L'augmentation due doses de deux materiaux (15 g/100 g) surbaissent la postérité des insectes examińes.
