Abstract
Lately there has been a concerted effort to elucidate the structure and function of the stylet bundle of suctorial insects. Aphids have received special attention because of their importance as vectors of plant viruses. Several workers have described their observations of stylets penetrating translucent tissues or membranes; for example, Bradley (1952), Mittler (1954), and van Hoof (1958). The movements most easily seen are rapid alternate oscillations at the stylet tips and a back and forth swinging of the entire stylet bundle as it enters a cell or other liquid medium.
