Fine structure of pegs on the palps of female culicine mosquitoes.

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