(Cucurbitaceae) in the Pest Grasshopper Zonocerus Variegatus L. (Pyrgomorphidae) By Ngnaniyyi Abdoul, Seino Richard Akwanjoh & Dongmo Ingrid Tonleu University of Dschang Abstract- The Muskmelon , Cucumis melo L., is a Cucurbitaceae widely cultivated in Cameroon for its nutritional and ethnomedicinal benefits. Species of Cucurbitaceae are known to contain several bioactive molecules that include the terpenoid cucurbitacins, which has been shown to cause significant molting defects and mortality in a variety of Coleoptera insect species such as Leperesinus fraxini PANZ(Coleoptera, Scolytidae) Stereonychus fraxini DE GEER (Coleoptera, Curculionidae). This study was designed to determine if an aqueous extract of Muskmelon, C. melo var. Cantaloupensis Americana , could profoundly affect the meiotic process in the Orthoptera grasshopper Zonocerus variegatus, a veritable food crop pest in Africa south of the Sahara. Different concentrations (0 µg/ml, 5µg/ml, 10 µg/ml, 20 µg/ml, 30 µg/ml, and 40 µg/ml) of aqueous extract of the leaves, fruits, and roots of C. melo were, respectively injected using the intraperitoneal method (into the hemocoel) of new reproductive and adult male individuals of Z. variegatus . Cytogenetic analysis revealed that Muskmelon extracts significantly reduced meiotic indexinduced meiotic chromosome abnormalities and significantly reduced chiasma frequency.
