Receptors of sex pheromones and abstinons inMusca domestica andGlossina morsitans

Abstract

Receptors arranged in two pairs on the inner and outer sides of the proximal end of the tibia of legs ofMusca domestica L. andGlossina morsitans morsitans Westwood are described here for the first time. In the male fly, these receptors function in perception of sex pheromones, as demonstrated in experiments in which the sense organs were coated with paraffin. Similar techniques showed that sense organs for abstinon are located on the tarsi. Scanning electron microscopy and light microscopy show that the tibial sense organs ofMusca may be sensilla of the coeloconic type.
