Abstract

On Scots pine, Neodiprion sertifer prefers the lowermost needle of fascicles on the distal one-third of shoots for oviposition. The amount of divergence between needles in a fascicle may influence the selection of oviposition sites, as the needles were further apart in egg-bearing fascicles. The interior diameter of resin canals was significantly greater on egg-bearing than non-egg-bearing needles.
