The distribution of agglutinins and lytic activity against Trypanosoma rangeli and erythrocytes in Rhodnius prolixus and Triatoma infestans tissue extracts and haemolymph

Memorias do Instituto Oswaldo Cruz, 1991
Haemolymph, heads, salivary glands, crops, midguts, hindguts, and Malpighian tubules from Rhodnius prolixus and Triatoma infestans were extracted in phosphate or Tris buffer saline with calcium, and tested for agglutination and lytic activities by ...

SYNCAS‐mediated CRISPR‐Cas9 genome editing in the Jewel wasp, Nasonia vitripennis

Insect Molecular Biology, Volume 35, Issue 1, Page 48-55, February 2026.
Maternal injection of Cas9 RNP together with BAPC and saponins (SYNCAS) results in efficient gene editing of Nasonia vitripennis offspring. The timing of injection and egg collection is important for maximising efficiency and reducing screening effort.

Nutritional geometry provides insight into the dual roles of natural and sexual selection in insect cuticular hydrocarbon evolution

Functional Ecology, Volume 39, Issue 12, Page 3646-3658, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions between natural and sexual selection have been integral to the development of sexual selection theory, yet the role of natural selection in sexual trait evolution has received far less empirical attention than the role of sexual selection, and the extent to

Genome Wide Mapping of Peptidases in Rhodnius prolixus: Identification of Protease Gene Duplications, Horizontally Transferred Proteases and Analysis of Peptidase A1 Structures, with Considerations on Their Role in the Evolution of Hematophagy in Triatominae

Frontiers in Physiology, 2017
Triatominae is a subfamily of the order Hemiptera whose species are able to feed in the vertebrate blood (i.e., hematophagy). This feeding behavior presents a great physiological challenge to insects, especially in Hemipteran species with a digestion ...

A new piece in the repeatome puzzle of Triatominae bugs: The analysis of Triatoma rubrofasciata reveals the role of satellite DNAs in the karyotypic evolution of distinct lineages

Insect Molecular Biology, Volume 34, Issue 6, Page 917-928, December 2025.
Satellite DNAs comprise the major component of the Triatoma rubrofasciata repeatome, highlighting their central role in genome composition and architecture. Satellite DNA families show recent amplification in heterochromatin and older, more divergent satellite DNAs located in euchromatin, indicating distinct evolutionary histories.

Studies on Trypanosoma rangeli Tejera 1920: VI. Developmental pattern in the haemolymph of Rhodnius prolixus

Memorias do Instituto Oswaldo Cruz, 1983
The morphological sequence of Trypanosoma rangeli development in the body cavity of Rhodnius prolixus is described. The metacyclic trypanosome is the product of successive division and transformation during the intra and extracellular development in the ...

The epicuticle in an insect, Rhodnius prolixus (Hemiptera) [PDF]

Proceedings of the Royal Society of London. Series B - Biological Sciences, 1947
Abstract The ʻepicuticle’ in Rhodnius consists of four layers. From within outwards these are: (i) the ‘cuticulin layer’ composed, it is suggested, of polymerized lipoproteins tanned by quinones; (ii) the ‘polyphenol layer’ rich in dihydroxyphenols; (iii) the ‘wax layer’ responsible for the waterproofing of the cuticle; (iv) the ...

Effects of the alarm pheromone on Triatoma pallidipennis behaviour

Physiological Entomology, Volume 50, Issue 4, Page 374-387, December 2025.
T. pallidipennis performs behavioural acts in response to volatiles emitted by mechanically disturbed conspecifics. T. pallidipennis shows a repellent response when exposed to volatiles emitted by mechanically disturbed conspecifics. Isobutyric and propanoic acids can be used as repellents of T. pallidipennis. Abstract Adults of some Triatomine species,

Characterization of Triacylglycerol Dynamics and Lipid Metabolism in the Beetle Tribolium castaneum

Archives of Insect Biochemistry and Physiology, Volume 120, Issue 3, November 2025.
Tribolium castaneum larvae accumulate triacylglycerol (TAG) during development, while adults rapidly deplete reserves post‐emergence. Under starvation, beetles prioritize protein catabolism over lipid mobilization, despite increased expression of lipolysis genes, revealing stage‐specific metabolic adaptations in this model insect.
