Survey Procedures<br />

Procedure<br />

Traps are hung from the branches <strong>of</strong> trees with a wire placing them at eye level<br />

(Fig. 4-6), between 1.5 and 2.0 m height and separated to a minimum <strong>of</strong> 100m<br />

between traps. Because the Dendrolimus moths are relatively large,<br />

consideration should be taken in using a trap size suitable for this species<br />

normally, including those commercially available for large lepidopterans.<br />

Modifications to milk carton traps (Fig. 4-7) have been approved for CAPS<br />

surveys (Jackson, 2011b). Altenkirch (1996) successfully used Variotraps with<br />

pheromone lures to monitor PTL populations.<br />
