Mid-infrared spectroscopy (MIRS) is a well-established technique in the field of chemical
analysis. Although it has been applied to problems in the entomological field for over 65 …

In insects, cuticular lipids prevent water loss and act as semiochemicals. Because of their
ecological function, the profile change across the insects' sex and development offers insight …

In many animals, there is a prolonged pre-reproductive period prior to sexual maturity. To
avoid premature mating attempts, it is common for phenotypic changes to occur during this …

The social wasps have a remarkable system of organization in which chemical
communication mediate different behavioral interactions. Among the compounds involved in …

A fundamental feature in the evolution of social insects is the separation of castes, and the
presence of wide differentiation between castes indicates a more advanced degree of …

Fish scales have been used to differentiate fish species and to give information on water
pollution, besides others different purposes. In the present work, we are proposing, for the …

The cuticular chemical composition plays a significant role in the recognition of nest mates in
social insects, thus functioning as a chemical signature of the colony. The structure of …

Facultative social parasitism has been recorded in several taxa of social insects. Most
recently, this phenomenon has been recorded in colonies of the neotropical social wasp …

Studies of venomous animals have shown that environmental and genetic factors contribute
to determining the chemical composition of venom. It is well known that external effects …

Studies related to communication on spiders show that, as in other invertebrates, the
interactions between conspecifics are also made through chemical signals. Therefore, in …
