Four structures are found on the maxillary palps of female culicine mosquitoes: microtrichia, scales, sensilla chaetica, and thin-walled, bulb-shaped organs. The bulb organs are localized on the distal half of the ventral part of palpal segment 4, have perforated walls, are carbon dioxide receptors (Kellogg, in press), and vary in number among the species from 29/palp on Aedes aegypti to 89/palp on Culex restuans. An explanation for observed behavioral responses to carbon dioxide is given.

Maxillary Palps

The sense organs on the antennae and maxillary palps of male Aedes atropalpus (Coquillett), Aedes aegypti (L.), Culex territans Walker, and Culex pipiens L. are similar to those observed on female culicines including water, olfactory, and carbon dioxide receptors. Although males have the same variety, they have fewer of each type of sense organ. The difference in number of any one type of sense organ is more variable in the female than the male except for the sensilla basiconica.

Culex Territans

The fine structure of the thin-walled pegs known to respond to carbon dioxide was studied in Aedes aegypti (L.), Culex pipiens L., and Culex territans Walker. Each peg is composed of an external cuticular structure with numerous pores which occur in groups, three bipolar neurons, and sheath cells. In A. aegypti two morphologically different types of neurons were found innervating the same sensillum: two electron-dense neurons and one electron-lucid neuron per peg. In addition to distinctive cell bodies and nuclei, the two types of neurons have different organization patterns of their dendritic processes within the lumen. Culex pipiens is shown to have several times more area available for perception of carbon dioxide than A. aegypti.

Abstract The ultrastructure of the mouthparts of Haematobia irritans (L.) was investigated by scanning electron microscopy. The morphological characteristics of the maxillary palps, labium (prementum and postmentum), labrum, hypopharynx, haustellum, and labellar lobes are described, as well as of the sensilla evidenced on all the surface of the mouthparts, and the set of different positions assumed by the mouth apparatus of this fly. Based on their morphology, 12 well-differentiated sensilla were identified, among three types of cuticular sensilla: trichoidea, coeloconica, and campaniformia. A slight sexual dimorphism in the sensilla patterns found in the mouthparts of H. irritans was evidenced. These observations are discussed with reference to the current literature on the functional morphology of sense organs of Insecta. These results could facilitate the recognition of the chemosensory sensilla by electrophysiological techniques, and foment future taxonomic and phylogenetic studies to better elucidate the evolution of Diptera, Muscomorpha.
