Modulation of microbial community associated to a host influenced by biotic and abiotic stresses
The emerald ash borer (EAB) is an exotic wood borer beetle native to China, that causes environmental and economic damages to ash trees in North America. Beetles are vectors of microbial communities which may play crucial roles in their adaptive capacities. Some environmental stress factors are reported to induce physiological events on the host trees, such as phytochemical responses, which may, in turn, affect the behavior of herbivorous insects. Considering the density of insects on ash trees as a factor triggering stress damage, we aimed to explore the dynamics of EAB gut microbiome when facing that factor.
