A nondestructive tree trunk funnel trap for capturing insects ascending stems of trees

摘要

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.
