Line overview

This subline of work is the continuation of one of the main lines of the laboratory during the direction of Dr. Patricia Juárez and is focused on the study of the composition, structure, metabolism, and function of the lipids and the cuticular proteins of insects, as well as the usefulness of cuticular hydrocarbons as a tool of chemical taxonomy.
It has recently been included the identification and molecular and functional characterization of genes of the integument involved in the biosynthesis of cuticular lipids and proteins to the traditional biochemical studies. They contribute to the role of cuticle barrier in the face of loss of water and insecticide penetration that participate in the biosynthesis of contact pheromone, among other multiple functions.
Within insects of medical importance, we mainly study triatomines, which are Chagas disease vectors. While, within insects of agronomic importance, our research is focused on coleoptera, which are stored grain pests as Tribolium castaneum. To do this, we use techniques such as quantitative real time, RNA sequencing, thin layer chromatography, column chromatography and gaseous chromatography coupled to mass spectrometry, as well as multivariant analyses of order and classification.
