Extract

Examination of the cephalic lobes of larvae of Psila rosae (F.) by means of light and scanning electron microscopes revealed the presence of 24 sensilla, ten campaniform, eight basiconic, four ampullaceous and two styloconic. By comparison with the known functions of similar sensilla in other insects, it is suggested that the ampullaceous and basiconic sensilla respond to plant emanations in soil, air and water, respectively, and that styloconic sensilla determine the palatability of the root hairs; the role of the campaniform sensilla is obscure.
