The ZAT (Terrestrial Animal Zootechnics) technical facility is dedicated to the management and maintenance of terrestrial organisms in the laboratory, studied at the Institute of Evolutionary Sciences of Montpellier. This enables the investigation of central research questions of the Institute, such as resistance to pathogens and insecticides, the genomics of cytoplasmic incompatibilities related to the endobacterium Wolbachia, adaptation to host plants in phytophagous organisms, and the phenotypic and genomic bases of sociality and sex determination. Currently, the activities of the ZAT facility involve the rearing of terrestrial invertebrates such as mosquitoes of the genus Culex, mites of the genus Tetranychus, ants of the genus Messor, and a colony of African pygmy mice.
