Abstract

Aphids in nature are normally either winged or wingless. However, it has been found that there also occur individuals which are intermediate in wing development: that is to say, some individuals have only partly formed wings and therefore are intermediate between the winged and wingless types. The production of large numbers of intermediate-winged aphids can be induced in the laboratory by artificial means such as certain combinations of light and temperature.
