“…Mello et al (1996) have shown that the haemolymph of R. prolixus contains a galactoside-binding lectin that enhances the formation of haemocyte-trypanosome clumps in vitro. In addition, there is very little evidence for melanization of these structures, despite reports of the ability of reduviid bugs to form melanized nodules in response to non-parasite, biological materials (Alvarenga et al, 1990). Possibly, the trypanosomes suppress the PpO system that generates melanin (see Section C2a below) by releasing surface components to modulate the activation of the PpO via reduction of the protease activity of the fat body (Gomes et al, 1999(Gomes et al, , 2003.…”

Several billion people are at daily risk of life-threatening vector-borne diseases such as malaria, trypanosomiasis and dengue, and the dark shadow of plague hovers in the few endemic foci where it waits ready to re-emerge in a deadly pandemic. The abortive attempt to control malaria in the 1960s showed us the problem that we face in eradicating vector-borne diseases. Research into these tropical diseases fell into neglect during the 1960s, but in the 1970s research was once more directed towards vectorborne diseases and more recent initiatives such as the Roll Back Malaria Campaign have kept them in the international spotlight. If we are not to repeat the mistakes of the past it will be necessary to use all of our knowledge of vector biology.cambridge university press Cambridge

This review outlines aspects on the developmental stages of Trypanosoma cruzi and Trypanosoma rangeli in the invertebrate host, Rhodnius prolixus. Special attention is given to the interactions of these parasites with gut and hemolymph molecules and the effects of the organization of midgut epithelial cells on the parasite development. The vector insect's permissiveness to T. cruzi, which develops in the vector gut, largely depends on the host nutritional state, the parasite strain and the molecular interactions with trypanolytic compounds, lectins and resident bacteria in the gut. T. rangeli invades the hemocoel and once in the hemolymph, can be recognized and activates the defense system of its insect vector, i.e., the prophenoloxidase system, phagocytosis, hemocyte microaggregation, superoxide and nitric oxide activity and the eicosanoid biosynthesis pathway. Taken together, these findings not only provide a better understanding of the interactions parasite -insect vector, but also offer new insights into basic physiological processes involved in the parasites transmission.
