The objective of this work was to evaluate the insecticide activity of powder-vegetables on Callosobruchus maculatus in Cajanus cajan beans, and the physiological quality of the treated seeds under laboratory conditions. Powder of Piper nigrum seeds, Eugenia caryophyllata floral parts, and Lycopersicum esculentum leaves caused mortality of 100, 100 and 80.9%, respectively; they reduced oviposition in 100, 100 and 98.21% and adult emergence in 100%. The emergence and the emergence velocity index of plantlets from seeds treated with these powders achieved satisfactory efficiency. However, seeds treated with Pimpinella anisum, Coriandrum sativum, Eucalyptus globulus, Cuminum cyminum and control did not emerge.
