Trapping system for longhorn beetles.

The study attempts to develop an efficient trapping system for the detection and monitoring of exotic bark and wood boring beetles, particularly longhorn beetles (Cerambycidae). The objective is to use areas in the south with substantial populations of native beetles to develop a generic trap for large wood borers before attempting trials in areas such as China and Russia. Several types of intercept traps will be tested with various host compounds such as ethanol and alpha-pinene.Each trapping site will be denoted with orange and green flagging. At each site, several trap models will be tested. Each trap will be suspended between trees with twine or hung on a holder made of conduit pipe. Each trap measures about 3 feet in height and will be placed at breast height. The collection cup on each trap will contain a solution of water, propylene glycol, formalin and soap. Traps will be set for periods of 2-3 months per trial, either in the fall or spring of each year for a total of four trapping periods. Traps will not be set during the winter or mid-summer periods. Host compounds will be released from sealed pouches ... the compounds migrate through the plastic sheeting of each lure
