Bed bugs (<i>Cimex lectularius</i> L.) exhibit limited ability to develop heat resistance - Fig 3

A. A large nymph that survived heat exposure, but was unable to complete the molting process. B. A magnified view of a heat exposed bed bug shown in the left image. This insect was attempting to molt, but failed to escape its exoskeleton. The epicranial suture is circled in white appears to have opened, but the bed bug failed to escape through it. C. Depicted in the image from left to right are three heat exposed nymphs that failed to successfully molt to next instar after heat exposure. On the right is an exuvia from a nymph that did successfully molt. Photo credit: John Obermeyer.
