An Attract and Kill bait. Last Call EucosmAK, was deployed for management of Western pine shoot borer, Eucosma sonomana in pine plantations and tree nurseries. Eucosma sonomana causes substantial economic losses in ponderosa, lodgepole, and Jeffrey pine in Western United States. Last Call very selectively removes male moths of the target species from the ecosystem with negligible impact on non-target organisms. Bait combine the selectivity of pheromone (only 0.21 g/ha, compared to 3.5-20 g/ha for mating disruption) with rapid toxicity of insecticides (only 7.92 g/ha, compared to 500-800 g/ha for conventional sprays). This bait retains the insecticide within a hydrophobic matrix that precludes run-off or drift, thus preventing ecosystem contamination or damage. Eucosma sonomana infested ponderosa pine plantations in California, Oregon, and Washington were treated with three different application rates of Last Call.
