Abstract

The "secondary" attraction occurring after log attack by the female ambrosia beetle, Trypodendron lineatum (Oliv.), and the reduction in attractiveness after males arrive on the log are not dependent directly on mating. The reduction seems to be associated with the males’ presence, which suggests that they produce a masking substance.

Résumé

L’attraction "secondaire", survenue après l’attaque des grumes, par la femelle du Scolyte birayé (Trypodendron lineatum (Oliv.)), et l’attraction réduite qui se produit après que le mâle atteint les grumes ne sont pas directement reliés à l’accouplement. L’attraction réduite semble reliée à l’apparition du mâle qui, peut-être, masque l’odeur de la femelle.
