none Cinara atrotibialis , monophagous on Pinus kesya , feeds on 1-4 year old pine trees. Population trend shows an alternate rise and fall with a reverse trend for its endoparasitoid, Pauesia laricis . Young aphids usually dominate the population structure and incidence of alatae is very low. The species leads anholocyclic life cycle.
