Host-tree selection by western pine shoot borer (Lepidoptera: Olethreutidae) in ponderosa pine plantations
Environmental Entomology 16 (5), 1145-1147
Abstract: Eucosma sonomana Kearfott, the western pine shoot borer, damages terminal shoots of pines by mining the pith and stunting growth of infested leaders. A study in central Oregon in a young ponderosa pine plantation showed that those trees with the largest terminal buds also produced the longest leaders. The larger buds were also favored for attack by the shoot borer. As a result, the potentially largest leaders in the plantation are most likely to be infested.
