Abstract: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 be infested than are inherently weaker shoots. Accordingly, direct comparisons of infested versus uninfested shoot lengths will underestimate actual growth loss. Two indirect methods of estimating growth loss are explored. Loss equivalent to over 25% of vertical growth in 1 year is indicated for each terminal shoot infested by a larva that develops to maturity.
