The Influence of individual cuticular hydrocarbons on nestmate recognition in the Japanese hornets was investigated.
Cuticular hydrocarbons were extracted with n-hexane from individuals of several colonies of japanese hornet, Vespa analis Fablicius (Hymenoptera : Vespidae) and analyzed by combined Gas-chromatography - mass spectrometry. Cuticular hydrocarbons were also extracted from individuals which caught by traps made with liquor and orange juice.
On the results of the GC-MS analyses, 12 major hydrocarbons and more than 20 miner components were detected from the extracts of the individual hornet, V. analis, even from the extracts of the individuals caught by a liquor orange-juice trap in short-term. The results showed some intraspecific variation of the quantities of each component of the hydrocarbon profiles, even in a same colony and same cast.
