Abstract

The free amino acids of the accessory glands of adult male variegated grasshopper, Zonocerus variegatus (Linnaeus) were investigated at five different ages after emergence of insects maintained oh cassava Manihot esculenta, Cranz using automatic amino acid analyser, Beckman 121 MB. Thirteen amino acid components were consistently detected from days 6 to 28: cystine, aspartic acid, serine, glutamic acid, proline, glycine, alanine, valine, tyrosine phenylalanine, histidine, lysine and arginine. Proline, alanine, glycine, glutamic acid and serine occurred in highest concentrations, comprising 14.27, 11.88, 11.09, 9.66 and 8.15 nmoles respectively throughout the 28-day experimental period. Total free amino acids fluctuated in the course of development of accessory gland with highest load at 28 days of age.

Résumé

Nous avons étudié les acides aminés purs des glandes accessoires de la sauterelle bariolée adulte et mâle, Zonocerus variegatus (Linnaeus) a cinq âges différents après l'émergence d'insectes nourris de manioc, Manihot esculenta, Cranz au moyen de l'analyseur automatique d'acides aminés, le Beckman 121 MB. Nous avons relevé, du premier au vingt-huitième jour, treize composants d'acides amines: la cystine, la sérine d'acide aspartique, la valine, la tyrosine phénylalanine, l'histidine, la lysine et l'arginine. Les plus fortes concentrations, entrestrées dans la proline, l'alanine, la glycine, l'acide glutamique et la sérine étaient, respectivement, de 14.27, 11.88, 11.09, 9.66 et 8.15 nmoles au cours des 28 jours de l'expérience. Le total des acides aminés a varié tout au long de la période du développement des glandes accessoires, le taux le plus éléve étant enrégistré à 28 jours.
