Grimes, E.W., & Cone, W.W. 1985a Control of the grape mealybug, Pseudococcus maritimus, (Homoptera: Pseudococcidae), on concord grape in Washington (USA).. Journal of the Entomological Society of British Columbia 82: 3-6.

Notes: Ten insecticides were evaluated for control of the mealybug, Pseudococcus maritimus (Ehrhorn), (Homoptera: Pseudococcidae) on Concord grape in south central Washington during 1981 and 1982. Efficacy was determined from the number of mealybugs in samples taken throughout the season and from preharvest evaluation of mealybug damage (honeydew and sooty mold, Clasdosporium sp.) to fruit clusters. Results showed that parathion, malathion, and permethrin (Ambush) effectively reduced mealybug numbers and resulted in reduced damage to clusters.
