Abstract

A simple and inexpensive non-destructive trap to catch insects as they ascend tree boles is described. The trap was tested in a capture–mark–recapture experiment on the Warren root collar weevil, Hylobius warreni Wood. A high percentage (77%) of marked H. warreni were recaptured at least once during a 12-day period and 54% were recaptured more than once, with one weevil recaptured eight times.

Résumé

On trouvera ici la description d’un piège simple, peu coûteux et non destructeur pour capturer des insectes qui grimpent au tronc des arbres. Le piège a été testé au cours d’une expérience de capture-marquage-recapture du charançon de Warren, Hylobius warreni Wood. Un fort pourcentage (77 %) des H. warreni marqués a été recapturé à au moins une reprise durant une période de douze jours, et 54 % plus d’une fois, avec un charançon pris à huit reprises.
