Scabies, pediculosis, bedbugs, and stinkbugs: uncommon presentations.

Parasitic agents determine some of the most common skin disorders. Although well known, they could present different manifestations or be modified by individual or external factors that make their diagnosis or treatment difficult. This review will discuss some of the most prevalent parasitic infections, scabies, and pediculosis and also mention reactions determined by contact with certain insects that, although rarely found, could induce important skin reactions.

A field study of mating between two species of bedbug in northern KwaZulu, South Africa.

The interspecific cross-mating of female Cimex lectularius Linnaeus with male Cimex hemipterus (Fabricius) results in a visible mark developing in the female ectospermalege. This mark has been used to record the frequency of mating between female C.lectularius and male C.hemipterus in sympatric wild populations in a DDT-sprayed area of northern KwaZulu, South Africa. A high percentage (11/16 = 69%) of C.lectularius females were marked, showing that these two species mate in nature.

Production of a hybrid between the bedbugs Cimex hemipterus and Cimex lectularius.

Of 479 eggs laid by female Cimex lectularius Linnaeus and C.hemipterus (Fabricius) mated by males of the other species, one was fertile and gave rise to a first stage nymph. The egg showed sculpturing typical of C.hemipterus, the female parent, and the nymph conformed to the narrow pronotum and abdomen of this species, being significantly different from C.lectularius in the width of the abdomen. Because the orientation and lengths of the bristles on the sides of the abdomen were distinctly different from C.hemipterus and closely resembled C.lectularius, the single nymph obtained from the cross C.hemipterus x lectularius was interpreted as being a hybrid rather than a product of parthenogenesis.
