El perfil característico de hidrocarburos cuticulares (HC) para la especie Triatoma longipennis, puede ayudar a la comparación entre especies y a identificar vectores de infecciones parasitarias. Resumen La quimiotaxonomía estudia las sustancias químicas de los grupos taxonómicos. americana color intensity of the chromatophores present in the wings caused by thermal transition under laboratory conditions.
The present investigation can be considered as the first initial study of its kind for, in terms of examining the changes in the S. Our results are in accordance with a previously published study in which was examined, as the Phaulacridium vittatum decrease of temperature caused darkening color change in melanin-type chromatophores. americana found negative correlation between the temperature and the degree of darkness (R2 = 0.8038).
This temperature was the extreme minimum that could tolerate. At 5☌, chromatophores intensify their color to brownish-black. At 45☌, degradation of color intensity was observed in the chromatophores present in the wings. Optical microscopy of the wings of the insects was used for live observation without coverslips or contrasting substances. As a substrate, a layer of soil, stones, and finally a layer of grass were used along with branches of bushes and leaves hydroponic lettuce, cabbage and the grass were used as food for the specimens. The adult specimens were collected using a mini-terrarium of dimensions 40x40x30 cm. The variation of the color intensity of the chromatophores present in the wings of was analyzed by exposing 31 specimens to thermal Schistocerca americana transitions within the range of 45-5 ☌.
