Schausberger, P. 1998 Survival, development and fecundity in Euseius finlandicus, Typhlodromus pyri and Kampimodromus aberrans (Acari, Phytoseiidae) feeding on the San Jose scale Quadraspidiotus perniciosus (Coccina, Diaspididae).. Journal of Applied Entomology 122: 53-56.

Notes: Studies were conducted in the laboratory at 25 plus or minus 1 deg C, 65 plus or minus 5% RH and LD 16:8. Crawlers of Q. perniciosus must be considered a suboptimal prey. Its nutritional value is discussed in relation to that of more adequate food sources. Data on development and fecundity are also discussed in relation to other phytoseiid species feeding on scale insects.
