Abstract

Measurements of photoconductivity and scanning electro-micrographs were obtained on the cuticula of workers in the Oriental Hornet, Vespa orientalis von Linné 1771 mainly on the yellow strips of the abdomen. A correlation was found between the electrical resistance and the pigment granular structure, both of which were affected by age, rate of illumination and feeding on various xanthines. Possible interrelations between behavior towards daylight, perception of light, the granular appearance and organic semiconductor-like behavior of the cuticula is discussed.
