Abstract
Insects have provided a model system for the study of feeding and nutrition, yielding key insights which are now being applied to vertebrates. Experiments to date have concentrated on the physiological state of the animal and the chemical composition of synthetic foods, but have omitted a central aspect of homeostatic regulation, namely the relationship of control mechanisms with environmental complexity. The aim of the present study is to investigate the pre- and post-ingestive regulatory responses of two related but ecologically disparate insect herbivores (solitarious and gregarious phases of the oligophagous Locusta migratoria and the arid-adapted polyphagous Schistocerca gregaria) to different distributions of synthetic and natural foods in controlled environments. Mutants of Arabidopsis will provide plants varying in nutrient and secondary chemistry.
