Abstract

Egg distribution on a ponderosa pine 14 feet tall of a species of sawfly in the Neodiprion fulviceps complex is presented. Females prefer to oviposit on current year’s foliage. There was no consistency in position of egg cluster on the needle, length of needle, age or size of branch, vertical position in the tree or number of eggs per cluster in needles of different age. Oviposition was highest on south, southeast and east vectors of the tree. Two needles per fascicle were used more often on one-year-old foliage than on current foliage.
