Abstract
Response of aggregated C. undecimnotata to chemical and physical stimuli have been investigated in a two-choice arena. Three set of experiments were performed. Bioassays were conducted to investigated wheter individuals responded: 1) to the mark of a conspecific, 2) stimuli from dummy beetles made of red glass baeds; 3) to a n-heptane body extracts of both sexes. All individuals were observed to determine the time spent and the walking parameters in each area of the arena.
