Pheromone Traps and Chemical Lures<br />
Dendrolimus pini and Dendrolimus sibiricus<br />
Pheromone traps with chemical lures are the preferred method to monitor adult<br />
populations. Population surveys for adult males should be done during the<br />
season <strong>of</strong> flight activity, normally between mid-summer months between June<br />
and August using pheromone traps or light traps. Pheromone traps and<br />
chemical lures to monitor adult male populations <strong>of</strong> Dendrolimus moths are<br />
commercially available. Delta, tetra, bucket, funnel and Variotrap traps which<br />
were designed to monitor lepidopteran populations are the most commonly<br />
used and are fitted with a lure containing the synthetic pheromone blend<br />
produced by the female moth. The pheromone components included in the lure<br />
are (Z,E)-5,7-Dodecadienal (also Z5,E7-12:Ald) and (Z,E)-5,7-Dodecadien-1ol<br />
(also Z5,E7-12:OH), typically in a 1:1 blend providing the highest capture<br />
rates (Kovalev et al., 1993, Alekseev et al., 2000, Klun et al., 2000; Kong et al.,<br />
2001, Khrimian et al., 2002, Kong et al., 2007, Baranchikov et al., 2007,<br />
Ostrauskas and Ivinskis, 2010). The chemical lures are placed on a rubber<br />
septum and hung inside the trap. A killing agent should be placed in the bottom<br />
<strong>of</strong> any traps to limit escape <strong>of</strong> insects, DDVP is recommended (Jackson,<br />
2011b).<br />
