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

open access: yesInsect 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

Comparative and phylogenomic studies on the mitochondrial genomes of Pentatomomorpha (Insecta: Hemiptera: Heteroptera)

open access: yesBMC Genomics, 2008
Background Nucleotide sequences and the gene arrangements of mitochondrial genomes are effective tools for resolving phylogenetic problems. Hemipteroid insects are known to possess highly reorganized mitochondrial genomes, but in the suborder Heteroptera

Disc mower versus bar mower: Evaluation of the direct effects of two common mowing techniques on the grassland arthropod fauna

open access: yesJournal of Applied Ecology, Volume 62, Issue 2, Page 360-370, February 2025.
Our findings suggest that mowing in general has a negative impact on abundant arthropod groups in grassland, regardless of the method used. Tractor‐driven double‐blade bar mowers do not seem to be a truly insect‐friendly alternative to a conventional disc mower.

PATHOGENICITY OF NATIVE BEAUVERIA BASSIANA (BALSAMO-CRIVELLI) VUILLEMIN ISOLATE ON DYSDERCUS CINGULATUS (HEMIPTERA: PYRRHOCORIDAE)

open access: yesJournal of Biopesticides
Entomopathogenic fungi (EPF) are the microorganisms thatspecifically infect and often kill insects and other arthropods. EPF is themost effective biocontrol agent against insects in the natural ecosystem whichcould be an effective alternative to chemical

Temperature Tolerance and Thermal Environment of European Seed Bugs

open access: yesInsects, 2020
Heteroptera, or true bugs populate many climate zones, coping with different environmental conditions. The aim of this study was the evaluation of their thermal limits and derived traits, as well as climatological parameters which might influence their ...

Comparative Analysis of Volatile Defensive Secretions of Three Species of Pyrrhocoridae (Insecta: Heteroptera) by Gas Chromatography-Mass Spectrometric Method. [PDF]

open access: yesPLoS ONE, 2016
The true bugs (Hemiptera: Heteroptera) have evolved a system of well-developed scent glands that produce diverse and frequently strongly odorous compounds that act mainly as chemical protection against predators.

First Report of Insect Species Associated With Domesticated African Baobab (Adansonia digitata L.) in Ghana

open access: yesInternational Journal of Forestry Research, Volume 2025, Issue 1, 2025.
The African baobab (Adansonia digitata L.) is a priority Pan‐African tree species. Insect pests that are associated with and damage domesticated baobab are largely unknown in the production areas of baobab. To identify and document insect pests associated with domesticated African baobab for the first time, mature and young domesticated baobab plants ...
