Abstract
Female as well as male mate choice has already been recognized in many insects. The traits responsible for the mate choice in a striped stink bug (Graphosoma lineatum L.) are not yet explored. This works concentrates on few possible traits responsible for mate choice in a striped stink bug. For this analysis free living copulating individuals as well as the single ones were collected. On two different locations animals were collected and their body length, pronotum broadness and coloration were measured. No differences were found in all measured traits between copulating and control individuals, showing no preferences when choosing copulation partner. Results also show no evidence of assortative mating, referring to the body length and the pronotum broadness of both sexes. All three measured traits seem not to have an influence on the mate choice of both sexes. Further experimental testing is needed to fully excluded importance of body size and coloration in mate choice of a striped stink bug.
