Abstract

Insect growth regulating properties of petroleum ether extracts of 10 indigenous plants were tested against Culex pipiens fatigans (Wied) and Musca domestica nebulo (Fabr) by continuous exposure and topical application methods. Out of the 10 plants, Acorus calamus and Azadirachta indica demonstrated insect growth regulatory (IGR) activity against C. p. fatigans and also against M. d. nebulo. There was IGR activity, but this was observed only when these extracts were used in higher concentration.

Résumé

Insecte produit régler accessoires de pétrole ether des dix plantes daus indégines avaient épreuve avait font usage Culex pipiens (Wied) fatigans et Musca domestica nebulo (Fabr) continue et l'application parmi des dix plantes, Acorus calamus et Azadirachta indica ont démontré l'activité de le progress des insect es reglementaires parmi C. p. fatigans. Ces plantes n'ont par révélé IGR activité de le progress M. domestica des insectes reglementaires prami à la concentration inferieur mair les ont trouvé a posseder IGR à la concentration supérieur.
