Abstract

An emergence trap for bark-inhabiting insects was constructed out of a 22.7-L plastic pail. Screened windows in the sides of the bucket provided ventilation. A plastic funnel in the bottom of the bucket held one of three sizes of container for live- or dead-trapping of emerged insects. In laboratory and field tests with lodgepole pine bolts infested with mountain pine beetle and associated insects, the traps had a trapping efficiency of 97.5%.

Résumé

Un seau en plastique de 22,7 L a été transformé en piège d’émergence pour capter les insectes vivant dans l’écorce des arbres. On a percé des ouvertures dans la paroi du seau afin de permettre la ventilation. Pour recueillir les insectes enfermés vivants ou tués, on a installé au fond du seau un contenant de l’une des trois dimensions existantes, retenu par un entonnoir en plastique. À la suite de tests faits en laboratoire ou à l’extérieur, au moyen de sections de tronc de pin tordu infesté de dendrochtones du pin ponderosa ou d’autres insectes, on a constaté que ce piège fonctionnait avec une efficacité de 97,5%.
