Insecticidal activity of bioproducts on Ceratitis capitata Wiedemann (Diptera: Tephritidae)

The aim of this study was to evaluate the insecticidal activity of the bioproducts proagrim, essential oil from fennel and orange oil, on the mortality of Ceratitis capitata Wiedemann (Diptera: Tephritidae). The study was divided into three parts: the first assay studied the insecticidal activity of the products on infested fruit; secondly, a bioassay was performed by ingestion of the bioproducts in an artificial diet, and the third assay assessed the activity of the products following topical application on insects. Insecticidal activity was evaluated by application of the products at concentrations of 0.0 (control), 10,000, 15,000, 20,000, 25,000 and 30,000 ppm. In general, proagrim and the essential oil of fennel induced higher mortality in larvae of C. capitata than orange oil. Useful information for the development of new tephritid control tools is provided by this study, because proagrim and essential oil from fennel are of potential commercial importance for the control of C. capitata, as they cause high mortality to the larvae of C. capitata in infested fruit.Keywords: Bioproducts, fruit-flies, red mombin fruit, Tephritideos.African Journal of Biotechnology, Vol 13(12), 1430-143
