Resumo
Termites are eusocial insects of isoptera order that part in seven
families. In this study we analyze the chirality of α-pinene in the defensive
secretion that C. cyphergaster (Isoptera, Termitidae, Nasutitermitinae) this
compound showed that among the majority of termite volatile. Along with
checking the chirality was made a study seeking to correlate the production
of each enantiomer, R(+)-α-pinene and S(-)-α-pinene, soil and climate data in
dry and wet seasons of year 2002 and 2003.
In the statistical data were used some statistical techniques such as
Detrended Correspondence Analysis, to predict the model, Analysis of
Variance for multiple comparison of means, and Redundancy Analysis to
show a correlation matrix by another and that have a preview of the
separation of groups.
The DCA analysis showed that the model is linear. The analysis of
variance for both the original data and for the transformed data showed that
the averages do not differ statically at 95%, because they have p>0,05.
The analysis of redundancy was not possible to explain the
environment by the response matrix, in the 95% level of confidence.
There was a production of enantiomeric α-pinene by the C.
cyphergaster populations, which can be an important factor to assist in
chemotaxonomic studies of these specimens. There is increased production
of the (S) enantiomer, but it was not possible to correlate this trend with soil
and climatic factors in statistically significant odds. The variation of the
enantiomérica composition can be related to factors other than soil and
climate, such as ecological factors, genetic, or eusocial.
