Among the insects that attack the filbert in the Pacific Northwest Melissopus latiferreanus (Walsingham), referred to in this paper as the filbert worm, has caused the growers the greatest concern on account of its direct damage to the nuts and the expense involved in sorting the infested nuts from the sound ones. Although the actual losses for the most part have not been serious, several locally severe infestations have developed, demonstrating the potential importance of the insect. The filbert worm has been under observation by the Entomology Department of the Oregon Agricultural Experiment Station for a number of years and that agency is now conducting experimental control tests against it (Thompson 1938). This paper is presented because the preliminary investigations on the biology of the insect, conducted at the Eugene, Oregon, laboratory of the Bureau of Entomology and Plant Quarantine, have brought to light certain interesting facts and trends which appear to be worthy of record.
