Pheromone traps to suppress populations of the smaller European elm bark beetle
Abstract Not Available – First paragraph follows: Dutch elm disease (DED) has devastated elm populations throughout large portions of the eastern and midwestern United States. This disease has gradually spread westward since its accidental introduction from Europe into North America in 1930. First discovered in California in Sonoma County in August, 1975, DED is a threat to elm populations throughout the state. The California Department of Food and Agriculture is committed to exploring the feasibility of eradicating the disease before it spreads from its initial infection sites.
