AbstractConotrachelus neomexicanus Fall occurs throughout the range of Pinus ponderosa Laws. in the central and southwestern United States. It is commonly found infesting ponderosa pine cones in north-central Colorado. C. neomexicanus is univoltine. Eggs are laid in second-year cones from May through July. Larvae mine extensively in the cones and drop to the ground for pupation in the soil. Adults emerge from the soil in late summer and early fall, return to the trees to feed on twigs, and presumably hibernate in sheltered locations during the winter A tachinid fly, Myiophasia sp. nr. ruficornis Tns., is an internal parasitoid of weevil larvae.

AbstractThe pine seedworm, Laspeyresia piperana (Kft.), is a common pest in cones of Pinus ponderosa Laws. in British Columbia and may destroy up to 50% of the seed.Moths emerge in May, mate, and lay eggs on second-year pine cones. Immediately after hatching, the larvae migrate to the centre of the cone and feed on seeds throughout the summer. In autumn, larvae tunnel into the cone axis to overwinter. Pupation occurs in spring.
