A large multinational team of scientists has successfully sequenced the whole genome of the common bed bug (Cimex lectularius), uncovering several traits that could reveal why this human ectoparasite is so resistant to pesticides.

“Analyses of the bed bug sequenced genome (650 Mb) and 14,220 predicted protein-coding genes provide a comprehensive representation of genes that are linked to traumatic insemination, a reduced chemosensory repertoire of genes related to obligate hematophagy, host-symbiont interactions, and several mechanisms of insecticide resistance,” the researchers wrote in a paper in the journal Nature Communications. “In addition, we document the presence of multiple putative lateral gene transfer events.”
The bed bug genome sequence shows genes that encode enzymes and other proteins that the bed bug can use to fight insecticides, whether by degrading them or by preventing them from penetrating its body. MORE
