ABSTRACT This study investigated the stimuli that trigger digging behavior in Acromyrmex subterraneus during nest building. The hypothesis was that the presence of the fungus garden and/or brood triggers the excavation of tunnels and chambers. For the experiment. the excavation rate of individually marked workers kept in plastic cylinders filled with soil was recorded. https://parisnaturalfoodes.shop/product-category/facial-exfoliant/
