Morphological studies of Cimex lectularius Linnaeus, 1758 (Hemiptera: Cimicidae)

In the family Cimicidae, genus Cimex stands out for its importance in public health. These hemipterans are known as “bed bugs” and their presence generally indicates poor hygiene poverty. lectularius is a hematophagous insect has global distribution. Brazil, control occurs indirectly, due to of other vectors. The real knowledge epidemiological situation still compromised by under-reporting. To contribute biology taxonomy these insects, morphological characters adults five nymphal instars C. were analyzed characterized means scanning electron microscopy (SEM). Morphological study SEM allowed characterization eggshell, each instar, sexual differentiation fifth instar nymphs, female, male external genitalia. this it was possible evaluate lectularius, all nymphs’ instars. It relevant characterize morphology since results obtained can actions, well taxonomic studies species.
