Abstract

The location of olfactory and gustatory sense organs in the larvae of the American bollworm, Heliothis armigera, have been studied using the scanning and transmission electron microscopy. The olfactory chemoreceptors of the larvae are located on the antennae, mostly on the top of the second antennal segment in the form of two trichoid sensilla, two basiconic sensilla, two styloconic sensilla, campaniform sensilla and a uniporous peg sensillum. The third antennal segment bears one basiconic sensillum and two styloconic sensilla. The gustatory sense organs are located on the mouthparts including the labrum, mandibles, hypopharynx, maxillary palps and labium. Trichoid sensilla have been located on the labrum. Epipharyngeal setae as well as long short spines are located in the epipharyngeal membrane. The basal segment of the maxillary palp bears three trichoid sensilla and one campaniform sensilla. The maxillary palp also bears four styloconic sensilla on the distal portion of the lateral protuberance and one styloconic sensillum at the apex of the medial protuberance. Close to the bases of the protuberances, there are three basiconic sensilla and one campaniform sensillum. The third apical segment of the maxillary palp carries three campaniform sensilla on its lateral side, while on its top, eight small basiconic sensilla are distributed.

Résumé

La localisation et l'ultrastructure des organs de sens olfactives et gastatives d'H. armigera ont été étudié á l'áide de microscope éléctronique á transmission et á balayage. Les chemorecepteurs olfactives de la larve sont situés sur l'ántenne, á l éxtrimité de seconde segment antennaire sous forme de deux sensilles basiconiques, deux sensilles styloconiques et sensille campaniforme. Le troisieme segment antennaire contient une sensille basiconique et deux sensilles styloconiques. Les organes de sens gastatives sont localises sur les pièces bucales. Une sensille trichoide est localisée sur le labrum. Un poil epipharyngéale, des epines longs et courts sont localisés sur la membrane epipharyngéale. Le segment basale de la palpe maxillaire contient terais sensilles trichoides et une sensille campaniforme. Le troisième segment apicale de la palpe maxillaire apporte trois sensilles campaniformes situees sur le cote lateral, tandis que l'extrimite apporte huit petites sensilles basiconiques.
