Pentatomidae bugs associated with sunflower crops in the northwest of Rio Grande do Sul state and the action of Euschistus heros (Fabricius, 1794) (Hemiptera: Pentatomidae) on sunfl ower seeds [PDF]

Biotemas, 2007
The goals of this study were to identify the species of bugs attacking sunflowers in the northwest of Rio Grande do Sul state and to estimate the damage caused during the R6 and R8 stages. The bugs present in ten sunflower crops were collected, and their

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.

Double‐Stranded DNA Reduces dsRNA Degradation in the Saliva and Significantly Enhanced RNAi‐Mediated Gene Silencing in Halyomorpha halys

Advanced Biology, Volume 9, Issue 9, September 2025.
The invasive pest Halyomorpha halys causes significant crop losses requiring innovative pest control strategies such as RNA interference (RNAi). However, oral RNAi is largely ineffective in H. halys. This study shows that double‐stranded DNA (dsDNA) stabilizes dsRNA in saliva by inhibiting a highly expressed nuclease.

Euschistus heros RNase silencing: dsRNA stability and effects on RNAi susceptibility

Journal of Insect Physiology
Nuclease (RNase) activity is a major limiting factor that reduces the effectiveness of RNAi-induced gene silencing across many insect species. In Euschistus heros, dsRNA degradation occurs predominantly upon contact with saliva, while midgut fluids exhibit moderate degradative activity and the hemolymph shows minimal or no RNase activity.

Molecular mechanism of ATP‐binding cassette transporter‐mediated insecticide resistance

New Plant Protection, Volume 2, Issue 3, September 2025.
Advances in functional genomics (RNAi and CRISPR/Cas9) and artificial intelligence‐driven structure prediction (e.g., AlphaFold) are elucidating how ATP‐binding cassette transporters mediate insecticide resistance to both synthetic chemicals and Bacillus thuringiensis toxins.

Embryonic Development of Appasus japonicus Vuillefroy, With Special Reference to Mouthparts Formation (Insecta: Heteroptera, Belostomatidae)

Journal of Morphology, Volume 286, Issue 5, May 2025.
In this study, we provide a detailed description of the embryonic development of Appasus japonicus, focusing on the formation of its specialized mouthparts. We identify homologies between the maxillary plate and maxillary palp and most parts of the stylet‐like mandibles and maxillae are housed within the labial palp.

Using red–green–blue vegetation indices to evaluate complex agronomical traits in soybean breeding

Agronomy Journal, Volume 117, Issue 1, January/February 2025.
Abstract High‐throughput phenotyping is an emerging tool that allows access to identify simple and complex traits, accelerating genetic discoveries and selection. Vegetation indices strongly correlate with several economic crop traits, allowing plant breeders to detect variation in breeding populations.
