    Notes: Abstract The design features of gustatory systems are considered in relation to the need for insect herbivores (or indeed any animal) to regulate their nutrient intake. The gustatory system (defined to include both peripheral and central components) should ideally be designed to reflect: (a) the average nutritional requirements of the insect during its various developmental stages; (b) the ‘predictably unpredictable’ variation in nutrient supply-demand which occurs about that average; and (c) the distribution and composition of foods available in the environment. A mathematical model is presented which makes detailed predictions regarding behavioural and electrophysiological responses to foods or simple solutions varying in nutrient content.

    Description / Table of Contents: Résumé La sélection des aliments a été suivie pendant les 15 premiers jours de vie imaginale des mâles et des femelles deLocusta migratoria L. Les insectes recevaient 2 régimes alimentaires, l'un contentant 10, 20 ou 28% de protéines, mais pas de carbohydrates assimilables, l'autre 10, 20 ou 28% de carbohydrates assimilables, mais pas de protéines. Les quantités consommées, le détail de la prise de nourriture, et les croissances somatique et reproductive ont été mesurés. Malheureusement, ces régimes artificiels n'ont pas permis le développement ovarien des femelles. Cependant, il y a des preuves convaincantes que les insectes ont contrôlé leur apport en protéines et en carbohydrates pendant la phase de croissance somatique par une sélection alimentaire et une modification de la consommation.
    Notes: Abstract Dietary selection was investigated during the first 15 days of adult life in male and femaleLocusta migratoria L. Insects were provided with two artificial diets, one containing 10, 20 or 28% protein but no digestible carbohydrate, the other 10, 20 or 28% digestible carbohydrate but no protein. Amounts eaten, detailed feeding patterns and somatic and reproductive growth were measured. Unfortunately the artificial diets did not support female reproductive development. Nevertheless, there was convincing evidence that insects regulated both protein and carbohydrate intake during the somatic growth phase by dietary selection and altered consumption.
