THE EFFECT OF WOODPECKER PREDATION ON WOOD-BORING LARVAE OF FAMILIES SIRICIDAE (HYMENOPTERA) AND MELANDRYIDAE (COLEOPTERA)1
Published online by Cambridge University Press: 31 May 2012
Abstract
Woodpeckers consume wood-boring larvae of families Siricidae and Melandryidae leaving three distinct types of mark on the tree. The distribution of marks in relation to decreasing prey population indicates that tapping is the principal means of locating larvae. Forty per cent of siricids and two per cent of melandryids are consumed by woodpeckers on individual feeding trees; as siricid population increases the proportion of larvae taken decreases.
