Hoy, M.A. 1990 3.6.3.2 Genetic Improvement of Natural Enemies of Armored Scale Insects.. Armored Scale Insects, Their Biology, Natural Enemies and Control [Series title: World Crop Pests, Vol. 4B]. Elsevier Amsterdam, the Netherlands 688 pp.

Notes: Abstract: At present no improved strains of natural enemies are used in a control program; possibilities are discussed; examples of breeding programs on Aphytis are given (temperature & pesticide resistance); hybridization and recombinant RNA techniques are discussed; factors limiting genetic improvement projects are listed. Keywords: biological control.
