Researchers Jose Pietri, Ph.D. (shown examining a cockroach under a microscope), and Dangsheng Liang, Ph.D., are co-authors of a review paper that that looks into possible connections between the microbes that live inside the insect gut (the gut microbiome) and insects’ ability to develop pesticide resistance. Both Pietri and Liang are scientists at Apex Bait Technologies Inc., a company that focuses on developing insect baits to control urban pests. Part of the company’s work includes investigating whether insecticide exposure might alter the insect’s gut microbiome. (Photo credit: Apex Bait Technologies Inc.)
