The aim of this study was to determine whether worker self-grooming,
allogrooming, and direct contact promotes the dispersal of substances among
members of the colony. For this purpose, a tracer (Sudan III dye) was applied
topically to a worker ant and the social interactions between the worker with the
tracer and workers without the tracer were studied. Additionally, the worker
heads were dissected to visualize whether or not the post-pharyngeal gland was
stained. The post-pharyngeal glands from 50% to 70% of workers were stained
depending on the size of the group. With the increase in the experimental group
size, the frequency of interactions between workers increased, with touching
being the most frequent behavior. The tracer dye was probably passed on by direct
contact between workers, followed by self-grooming and allogrooming. These
behaviors are responsible for the rapid dispersal of substances among colony
members as observed in our experiment. The results therefore support the
hypothesis that contact with substances promotes the contamination of nestmates,
even in the absence of feeding, serving as a model for further studies on the
contamination of workers with the active ingredients of insecticides.
