The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

Insect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Morin hydrate reduces survival and fertility, delays development and weakens lipid reserves in Aedes aegypti

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 592-602, September 2025.
Morin hydrate promoted mortality and reduced the rate of pupation and egg laying in Aedes aegypti larvae that survive treatment. Morin hydrate reduces the levels of triacylglycerol, the main lipid reserve in A. aegypti larvae. The expression of proteins involved in lipogenesis and lipolysis was downregulated and upregulated, respectively, in larvae ...

Comparison of hemocytes of 5th-instar nymphs of Rhodnius prolixus (Stal) and Rhodnius robustus (Larousse 1927), before and after molting

Revista de la Facultad de Medicina, 2015
Background. The immune response of insects involves humoral factors and cellular elements known as hemocytes. There are different reports that explore the response of hemocytes to infections, but the effect that molting has on this response has not been

RNA‐Based Biopesticides: Pioneering Precision Solutions for Sustainable Aquaculture in China

Animal Research and One Health, Volume 3, Issue 2, Page 165-176, May 2025.
The Chinese dragon represents RNA biopesticides, which effectively counteract bacterial, viral, and parasitic threats, safeguarding aquatic life. This method is precise, focusing solely on harmful agents and sparing beneficial aquaculture species. Its innovative nature protects aquatic environments while reducing ecological footprint.

The cryptonephridial/rectal complex: an evolutionary adaptation for water and ion conservation

Biological Reviews, Volume 100, Issue 2, Page 647-671, April 2025.
ABSTRACT Arthropods have integrated digestive and renal systems, which function to acquire and maintain homeostatically the substances they require for survival. The cryptonephridial complex (CNC) is an evolutionary novelty in which the renal organs and gut have been dramatically reorganised. Parts of the renal or Malpighian tubules (MpTs) form a close

Proteases of haematophagous arthropod vectors are involved in blood-feeding, yolk formation and immunity : a review [PDF]

, 2017
Ticks, triatomines, mosquitoes and sand flies comprise a large number of haematophagous arthropods considered vectors of human infectious diseases. While consuming blood to obtain the nutrients necessary to carry on life functions, these insects can ...
