Cutright, C.R. 1951 Comstock mealybug in Ohio.. Journal of Economic Entomology 44(1): 123-124.

Notes: The history of this species for the 10 years that it has been known on apple in Ohio presents an illustration of control by biological means, principally by the use of parasites. The continued and efficient correction of injury over a 6-year period by this means is encouraging.
