Mating and starvation modulate feeding and host-seeking responses in female bed bugs, Cimex lectularius

Abstract Reproductive fitness and survival are enhanced by adaptive behaviors that are modulated by internal physiological states and external social contexts. The common bed bug, Cimex lectularius, is an obligate hematophagous ectoparasite that requires host blood for growth, development, and repro...
