Cabbage aphid: effect of isolation on form and on endocrine activity.
Isolated wingless cabbage aphids, Brevicoryne brassicae (L.), produced only wingless young. Aphids isolated from birth all became wingless, whereas over 50 percent of grouped controls developed wings. Isolation caused hyperactivity of the corpus allatum; this hyperactivity may have caused the wingless form.
