Abstract
In studying insect populations it is often advantageous to have a rapid method for estimating population densities. In the present paper, methods are presented for estimating the density of eggs of the fir engraver, Scolytus ventralis LeConte, from the number of attacks or the gallery length.This publication has 1 reference indexed in Scilit:
