Variação Intra e interespecífica na composição de hidrocarbono cuticular da vespa Mischocyttarus consimilis por FTIR-PAS

Abstract

One of the conditions that had favored the evolution and maintenance of the socialidade in the insects is the ability of recognition nestmate other individuals. The recognition between the social insects is mediated by chemical signals that are soon acquired after the emergency of the adult and vary in accordance with the tasks played for the individuals in the colonies. In this context, this work had as objective to evaluate the moment where adult of wasp M. consimilis they acquire the chemical signature of its colonies and the variation of the profiles hydrocarbons to cuticular between queens, laborers and males. The used method, not usual, was optic Fourier transform infrared photoacoustic spectroscopy detention (FTIR-PAS) directly in gáster of each individual. It was possible to conclude by means of the analyses that young individuals lead of 3 the 4 days to acquire the chemical signature of the colony and that this profile varies between chaste and the sex, being that the profile of laborers was next to the ones to queens, which probably it becomes related bigger similarity of tasks executed for these individuals in the colony.
