Two aerial applications of microencapsulated pheromone were conducted on five 20.2 ha plots to disrupt western pine shoot borer (Eucosma sonomana Kearfott) and ponderosa pine tip moth (Rhyacionia zozana (Kearfott); Lepidoptera: Tortricidae) orientati

Pheromone disruption of the mating western pine shoot borer, Eucosma Sonomana Kearfott, was tested in young lodgepole pines, Pinus contorta Douglas, in central Oregon. About 12.5 g of pheromone per hectare was applied in Hercon luretape to five 6-ha

Stands of dense, natural ponderosa pine (Pinus ponderosa var. ponderosa) regeneration were operationally, precommercially thinned at seven sites - four on Nez Perce Tribal lands in northern Idaho and three on Spokane Tribal lands in eastern Washingto

The biology of the western pine shoot borer, Eucosma sonomana Kearfott, was investigated on young lodgepole pine ( Pinus contorta Dougl.) from 1987 through 1989 in central Oregon. In the stands studied, 65-80% of the terminals were infested. Attacks

Incidence of the western pine shoot borer, Eucosma sonomana Kearfott, and tree growth measurements from 5687 ponderosa pines, Pinus ponderosa Dougl. ex Laws., were recorded in the Calf Pen plantation Payette National Forest, ID. The percentage of tre

Male moths of the Douglas-fir tussock moth ( Orgyia pseudotsugata [Mc-Dunnough]), the western spruce budworm ( Choristoneura occidentalis Freeman), and the western pine shoot borer ( Eucosma sonomana Kearfott), were equally attracted to their respect

Larvae of the western pine shoot borer, Eucosma sonomana Kearfott, mine in the pith of the terminal shoots, causing loss of vertical growth of ponderosa pine, Pinus ponderosa Douglas ex Laws. Shoots that are potentially more robust are more likely to

Survey and control measures are available for the western pine shoot borer, Eucosma sonomana Kearfott, but timing is a problem because of the cryptic nature of the insect in the field. In central Oregon, key features of the insect’s seasonal histor

Damage of Eucosma sonomana Kearfott to Pinus ponderosa Lawson was significantly reduced (46 to 73%) by mating disruption with low seasonal dosages (3.5 to 5 g/ha) of synthetic pheromone (4:1 mix of Z-9 and E-9 dodecenyl acetates) released from widely
