...V. Harraca; C. Ryne; G. Birgersson; R. Ignell SUMMARY The resurgence in developed countries of the common bed bug, Cimex lectularius , has led to a search for new sustainable methods to monitor and control this human ectoparasite. Because of increased resistance to insecticides, traps baited...

... superfamily, have evolved independently to serve the apyrase reaction. Both families require either Ca 2+ or Mg 2+ for their action. A novel apyrase enzyme sequence, with no homology to any other known protein sequence, was found recently in the salivary glands of the hematophagous bed bug Cimex lectularius...

...Jesus G. Valenzuela; José M. C. Ribeiro ABSTRACT Cimex lectularius and Rhodnius prolixus contain salivary nitric oxide (NO) that may help them to feed on their vertebrate hosts by promoting vasodilation and inhibiting platelet aggregation. Salivary NO is associated with heme proteins (nitrophorins...

...Jesus G. Valenzuela; F. Ann Walker; José M. C. Ribeiro ABSTRACT Salivary gland homogenate of the bedbug Cimex lectularius caused vasodilation of the preconstricted rabbit aortic ring in the absence of endothelium. Vasodilation was augmented in the presence of superoxide dismutase and inhibited...
