    Description / Table of Contents: Summary 1. The nest sections of three formicaria ofFormica rufa L. andF. polyctena Först. were heated with an infrared lamp. Characteristic changes in the structure of the detritus dome were obtained by changing the distance of the lamp from the nest. 2. The increase of detritus cannot be used as an accurate measure of colony growth. The building of the detritus dome is largely influenced by climatic factors. 3. The effects of protecting ant colonies by placing wire mesh over the dome are discussed.
    Notes: Résumé 1. Les nids de trois fourmillières deFormica rufa L. etF. polyctena Först. furent irradiés avec une lampe à infra-rouge. Le déplacement de la lampe par rapport au nid a provoqué des modifications caractéristiques dans le mode de construction du dôme de la fourmillère. 2. L'augmentation du volume d'un nid ne peut pas être considérée valablement comme l'indication d'un accroissement de la colonie de fourmis car la construction du dôme de détritus est largement influencée par des facteurs climatiques. 3. Les effets de la protection des nids de fourmis au moyen d'un grillage appliqué sur le dôme sont discutés.
