Der Feinbau der Scolopidien im Johnstonschen Organ von Aëdes aegypti L.

Abstract
The scolopidia of Aedes aegypti contain 2 cilia which are rooted in sensory cells form special structures. The cilia lie in the interior of 2 cuticular hair sheaths, the outer of which is formed by a large sheathing cell, the inner by a hair (scolops) cell. In comparison with typical hair sensilla it is interpreted as a follicle or hair forming cell of a sunken hair. The reception of a stimulus results presumably by a shifting of the outer to the inner hair sheath by means of the cilia attached to the inner sheath.
