Relationship of infestation by the sequoia pitch moth (Lepidoptera: Sesiidae) to Monterey pine trunk injury
Environmental Entomology 12 (3), 979-981
Abstract: The larva of the sequoia pitch moth, Synanthedon sequoiae (Hy. Edwards), causes pitch masses on the trunks of susceptible conifers. Emergence of adult moths occurred over a period of 2 to 4 months in coastal central California. Physical injury to the trunks of Monterey pine incited increased larval infestations, particularly when injury was inflicted in the several months before, and during, the period of moth emergence. A portion of the pitch moth larval population appears to require more than 1 year to complete development to the adult stage.
