Midgut glycosidases of Rhodnius prolixus

Insect Biochemistry, 1984
Abstract Through the use of p- nitrophenylglycosides the presence of α- and β-glucosidase, α- and β-galactosidase, α- and β-manosidase, α-fucosidase, β-N- acetylglucosaminidase , α- and β-N- acetylgalactosaminidase activities were detected in the crop and intestine of the blood sucking bug Rhodnius prolixus. All activities have an

THE HEMOCYTES OF RHODNIUS PROLIXUS STÅL

The Biological Bulletin, 1965
1. The hemocytes of Rhodnius prolixus have been studied with phase contrast microscopy, after supravital staining, and in fixed and stained smears.2. With phase contrast microscopy, the following categories of circulating cells can be readily identified: (a) non-dividing and mitotically-dividing prohemocytes, (b) non-vacuolated and vacuolated ...

Nitric oxide effects on Rhodnius prolixus's immune responses, gut microbiota and Trypanosoma cruzi development.

Journal of insect physiology, 2020
The immune system of Rhodnius prolixus comprehends the synthesis of different effectors that modulate the intestinal microbiota population and the life cycle of the parasite Trypanosoma cruzi inside the vector midgut. One of these immune responses is the

Deciphering the role of Rhodnius prolixus CYP4G genes in straight and methyl‐branched hydrocarbon formation and in desiccation tolerance

Insect molecular biology (Print), 2020
Insect cuticle hydrocarbons are involved primarily in waterproofing the cuticle, but also participate in chemical communication and regulate the penetration of insecticides and microorganisms.

The histology of vitellogenesis in Rhodnius prolixus

Journal of Insect Physiology, 1968
Abstract The general histology and protein distribution as revealed by staining with mercury bromphenol-blue of the ovaries of mated Rhodnius prolixus were studied at various times after feeding. Vitellogenesis began on the second day after feeding and continued until the ninth day, when it gradually decreased. Vacuolation of the β and late γ oocytes

Silencing of ATG6 and ATG8 promotes increased levels of triacylglycerol (TAG) in the fat body during prolonged starvation periods in the Chagas Disease vector Rhodnius prolixus.

Insect Biochemistry and Molecular Biology, 2020
Rhodnius prolixus is an obligatorily hematophagous insect known as an important vector of Chagas disease. Autophagy is a conserved cellular mechanism that acts in response to nutrient starvation, where components of the cytoplasm are sequestered by a ...

Injury metabolism in an insect, Rhodnius prolixus

Journal of Insect Physiology, 1970
Abstract Injury of Rhodnius larvae, in which growth and development are arrested by decapitation 1 day after feeding, results in an increase in the rate of oxygen consumption to levels characteristic of fed larvae in which these processes are not interfered with. This increase occurs in the period 2 to 5 days after wounding.

Sulfated glycosaminoglycans from ovary of Rhodnius prolixus

Insect Biochemistry and Molecular Biology, 2001
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.

THE GORGING RESPONSE IN RHODNIUS PROLIXUS STĂHL

Canadian Journal of Zoology, 1965
Rhodnius prolixus nymphs confined in an artificial feeding apparatus could be induced to gorge on 0.15 M NaCl solutions at pH 7.0 containing 10−3 M concentrations of chemicals having phosphate bonds of high energy release. The di- and tri-phosphates of adenosine, guanine, inosine, cytosine, and uridine all showed high gorging factor activity.
