Electrophysiological Studies on the Dorsal and Anterior Organs of the Onion Fly Larva, Hylemya antiqua Meigen (Diptera: Anthomyiidae)

Abstract

Electrophysiological experiments were conducted to confirm the functions of the dorsal and the anterior organs of the onion fly larva Hylemya antiqua Meigen, which had been considered morphologically to be olfactory and gustatory. The dome of the dorsal organ responded to di-n-propyldisulfide, the onion odour and ethyl acetate, and thus proved to have an olfactory function. The anterior organ responded to 1 M solutions of various sugars and salts, and was thus confirmed to have a gustatory function. © 1987, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
