Effect of Chir Pine Cone Beetle , <I>Chlorophorus strobilicola</I> (Coleoptera: Cerambycidae) on the Seed Efficiency of <I>Pinus roxburghii</I>

Abstract

Chlorophorus strobilicola causes seed loss in Pinus roxburghii. Seed loss is directly related to seed efficiency (S.E). There is negative correlation between seed efficiency and degree of infestation. As the attack of C. strobilicola increases from light to severe the seed efficiency decreases.
