title: [Asymmetry of antennal grooming in the cockroach (Periplaneta americana)].
abstract: The present study was conducted to determine the key features of antennal grooming of male American cockroaches in neutral circumstances. It was shown for the first time that the right antenna was cleaned significantly more often than the left one, which indicates the presence of functional asymmetry of antennal grooming in this insect species. At the same time, no statistically significant asymmetry was found for grooming of antennal bases and legs. Morphological asymmetries of antennae and legs and/or brain lateralization are the plausible sources of observed behavioral asymmetry in antennal grooming.
