Thin-layer chromatography of carbohydrates secreted by larvae of wasps and those formed by aphids, Chaitophorus populi revealed the presence of the following major constituents: glucose, fructose, sucrose, melezitose, maltose and 4G-α-glycosylsucrose.

It is suggested that these sugars serve as powerful attractants to the Oriental hornet, Vespa orientalis.

This suggestion was compared with Wheeler's (1928) opinion on the social organization among social insects.
