Development of a chemically defined diet for ants
J. Straka and H. Feldhaar

A chemically defined diet is a useful tool for the study of nutritional physiology of organisms. We have developed such a diet for Camponotus carpenter ants to facilitate experiments on nutritional requirements of these ants. Worker colonies of Camponotus floridanus were fed with a chemically defined diet, containing all essential minerals, amino acids, vitamins, growth factors and sucrose in an agar matrix. After 13 weeks, neither the number of raised pupae, their dry weight, nor the mortality of workers in subcolonies fed with this diet differed significantly from control colonies fed with Bhatkar-Whitcomb-agar, in addition to cockroaches and diluted honey. Therefore, this diet is adequate for a normal brood production and a maximal growth rate of C. floridanus larvae, at least for a period of three months. This diet should be suitable for ants that are able to feed on agar-based food resources in general.

A new one tested for Rhytidoponera in the Online First of Insectes Sociaux.

Description of a simple synthetic diet for studying nutritional responses in ants
A. Dussutour and S.J. Simpson


Abstract. A chemically defined diet is a powerful tool for the study of nutritional physiology.We have developed a simple, standardized diet for Rhytidoponera ants to facilitate experiments on nutrititional regulation and nutrient balancing in these ants. Colonies of Rhytidoponera metallica were fed with a standardized diet, containing a 1:2 ratio of total proteins to digestible carbohydrates. After 8 weeks, colony performance (number of brood raised, the mass of pupae, and the mortality of workers) was superior to that of colonies fed with Bhatkar-Whitcomb diet and similar to colonies fed with Drosophila and honey-water.
