NOTES ON A PINE-FEEDING BUDWORM, CHORISTONEURA LAMBERTIANA PONDEROSANA (LEPIDOPTERA: TORTRICIDAE), IN THE COLORADO ROCKIES

Abstract
Choristoneura lambertiana ponderosana Obraztsov is commonly found infesting its main host, Pinus ponderosa Laws., in Colorado. It is also known from Wyoming, South Dakota, and Montana. Pinus flexilis James is a host in Montana, and in Colorado ponderosa pine dwarf mistletoe, Arceuthobium vaginatum subsp. cryptopodum Hawksworth and Wiens, is also utilized as a food plant. Adults fly and oviposit in midsummer; newly hatched larvae overwinter in hibernacula and emerge in the spring to feed on new foliage. Pupation takes place in the feeding area. There is one generation per year.
