AB - AbstractThe red pine cone beetle,Conophthorus resinosaeHopkins, is the most common of 3 insects that destroy whole cones and reduce yields in seed production areas (SPAs) of red pine,Pinus resinosaAil. Adult beetles are on the ground for overwintering from ca. Oct. 22–ca. May 10. After low-intensity burning of naturally accumulated fuels on 0.2-ha plots gave promising adult kills, six 0.7- to 21-ha SPAs were treated by backfire or strip-head fire burning in Minnesota, Wisconsin, and Michigan.Conophthorusinfestation was greatly reduced in burned SPAs 4 ha and larger, and cones free of all cone destroyers were significantly increased in 4 SPAs by 11–45%. Combined infestation by the red pine cone moth,Eucosma monitoranaHeinrich, and the red pine cone worm,Dioryctria disclusaHeinrich, went up or down after treatment depending on several factors. AdverseEucosma-Dioryctriainfestation behavior was minimized when SPAs with heavy cone crops were treated. Burning areas of sufficient size in heavy crop years the fall or spring before harvest seems a promising way to protect SPA crops from cone destroying insects.
