Abstract

Artificial selection was applied to several lines of Aphytis lingnanensis Compere (Aphelinidae) for more than 100 generations in an attempt to enhance tolerance to climatic extremes. Significant results included: (1) improved tolerance to temperature extremes as a result of selection; (2) irradiation failed to contribute measureably to enhanced tolerance; (3) the temperature tolerance was apparently well fixed genetically; and (4) general hardiness as indicated by adult longevity was improved coincidentally.
