Abstract

Megaplatypus mutatus (= Platypus mutatus) (Chapuis), an ambrosia beetle (Coleoptera: Platypodidae) native to South America, is a forest pest that attacks live standing trees, affecting commercial poplar and other broadleaf plantations. Traditionally, single-chambered emergence traps have been used to collect live beetles for field and laboratory studies. However, the lack of separation in these chambers results in antagonistic interactions between individuals. Wounded M. mutatus are incapable of successful reproduction and are of little value in physiological and behavioral experiments. We introduce a new, multiple-chambered trap that isolates individual insects until collection, thus increasing the number of uninjured and fully functional insects available for physiological and behavioral experiments.

Résumé

Megaplatypus mutatus (= Platypus mutatus) (Chapuis), un scolyte ambrosia (Coleoptera: Platypodidae) indigène d’Amérique du Sud, est un ravageur qui attaque les arbres vivants sur pied, ce qui affecte les plantations commerciales de peupliers et d’autres essences à feuilles larges. Pour les études de terrain et de laboratoire, on récolte généralement les insectes vivants à l’aide de pièges d’émergence comprenant une seule cellule. Cependant, l’absence de séparation dans ces cellules permet des interactions agonistes entre les individus. Les M. mutatus blessés sont incapables de se reproduire avec succès et sont de peu d’utilité pour les expériences de physiologie et de comportement. Dans notre étude, nous avons mis au point un nouveau piège à cellules multiples qui isole les individus jusqu’au moment de la récolte, ce qui fournit un nombre plus élevé d’insectes sains et complètement fonctionnels pour les expériences physiologiques et comportementales.
