Abstract

Three simple linear regression equations were developed to estimate the numbers of eggs in spruce budworm, Choristoneura fumiferana, egg masses in Michigan. One equation was developed for each of 2-row, 2- row + , and 3-row egg masses. A table of estimated numbers of eggs per egg mass is given for each of the three row types for egg mass lengths from 1 to 13 mm.
