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.

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.

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.

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

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.

Susceptibility of Euschistus heros (Fabricius, 1798) (Hemiptera: Pentatomidae) nymphs to Bacillus spp. strains

Entomological Communications
Soybean crops are subject to various phytophagous insects, among which the Neotropical brown stink bug Euschistus heros (Fabricius, 1798) (Hemiptera: Pentatomidae) stands out.

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.

Morphology and distribution of antennal sensilla of Plautia stali (Hemiptera: Pentatomidae)

Entomological Research, Volume 54, Issue 10, October 2024.
Abstract In this study, the morphology and distribution of antennal sensilla of male and female adults of Plautia stali were investigated using scanning electron microscopy. In both sexes, the antennae of P. stali were composed of a scape, two‐segmented pedicels (P1 and P2) and two‐segmented flagellomeres (F1 and F2).

Study of the overwintering ecology of the hazelnut pest, Palomena prasina (L.) (Hemiptera: Pentatomidae) in a perspective of Integrated Pest Management

Journal of Applied Entomology, Volume 148, Issue 1, Page 34-48, February 2024.
Abstract Palomena prasina, the green shield bug (GSB), is widely distributed in the Eurosiberian region. In the Southwest of France, it is considered as a serious pest of hazelnuts, its feeding punctures lead to blank hazelnuts and kernel necrosis, causing heavy losses in commercial orchards. To date, no Integrated Pest Management strategy is available
