Abstract

Mature male Pseudohylesinus nebulosus (LeConte) walking on Douglas-fir logs were strongly arrested and stridulated at a female gallery or artificial galleries with female frass, but not at artificial galleries without frass. This response diminished after the female had accepted a male in the gallery. Mature males emitted distinctive chirps for stress, attraction, and rivalry, all of which were different from chirps of immature males, and pushed intruding males from the gallery. In contrast, reproductively immature adult males were only weakly arrested both at artificial galleries and those of feeding females, and were not aggressive toward other males. Only stress chirps of immature males were distinguishable from chirps in other contexts. These observations suggest that adult reproductive maturation includes development of close-range olfactory and acoustic signals and territorial behavior.

Résumé

Des mâles matures de Pseudohylesinus nebulosus (LeConte) marchant sur des billes de sapin Douglas ont été fortement arrêtés et ont stridulé devant une galerie de femelle ou des galeries artificielles contenant des déjections de femelles, mais pas devant des galeries artificielles sans déjections. La réponse s’est atténuée après que la femelle ait eu accepté un mâle dans la galerie. Les mâles matures émettent des grésillements distincts pour l’état de tension, l’attraction et la rivalité, lesquels diffèrent des grésillements de mâles immatures; ils repoussent les autres mâles s’introduisant dans les galeries. Par contre, les mâles adultes mais reproductivement immatures n’ont été que faiblement arrêtés soit devant des galeries artificielles, soit devant celles de femelles s’alimentant, et n’ont pas montré d’agressivité envers les autres mâles. Seuls les grésillements de tension des mâles immatures peuvent être distingués des grésillements associables à d’autres situations. Ces observations indiqueraient que la maturation reproductive des adultes comprend le développement de signaux olfactifs et acoustiques de courte portée, de même que du comportement territorial.
