C13 Oviposition behavior of Ooencyrtus venatorius, egg parasite of Rhodnius prolixus

Effects of sub-lethal high temperature on an insect, Rhodnius prolixus (Stål.). IV. Egg formation, oviposition and sterility.

It has long been known that the physical factors of the environment exert profound effects on the various physiological activities of insects, and that temperature is one of the most important of these factors (Uvarov, 1931; Wigglesworth, 1953; Bursell, 1964). Within a biological range the reproductive activity of insects, like any other biological process, is enhanced by rise in temperature, b...

[Blood-feeding of Rhodnius prolixus].

Triatomines (Hemiptera: Reduviidae) are blood-sucking insect vectors of the protozoan Trypanosoma cruzi which is the causative agent of Chagas' disease. Rhodnius prolixus is the most epidemiologically important vector of T. cruzi in Colombia. Triatomines are regarded to be vessel-feeders as they obtain their blood meals from vertebrate hosts by directly inserting their mouthparts into vessels. ...

Sulfated glycosaminoglycans from ovary of Rhodnius prolixus.

We have characterized sulfated glycosaminoglycans from ovaries of the blood-sucking insect Rhodnius prolixus, and determined parameters of their synthesis and distribution within this organ by biochemical and histochemical procedures. The major sulfated glycosaminoglycan is heparan sulfate while chondroitin 4-sulfate is a minor component. These glycosaminoglycans are concentrated in the ovarian...
