Evaluating resistance of the soybean block technology cultivars to the Neotropical brown stink bug, Euschistus heros (F.)

Journal of Insect Physiology, 2021
Laboratory studies were conducted with the Neotropical brown stink bug, Euschistus heros (F.), to evaluate nymphal and adult biology on immature pods of soybean, Glycine max (L.) Merrill (Fabaceae), bearing the block technology (resistant to stink bug damage - cvs. BRS 391, BRS 543 RR and BRS 1003 IPRO) compared to a susceptible cultivar (BRS 5601 RR).

Imidacloprid-mediated alterations on the salivary glands of the Neotropical brown stink bug, Euschistus heros

Ecotoxicology, 2021
The management of the Neotropical brown stinkbug Euschistus heros (Hemiptera: Pentatomidae) in soybean fields has been heavily dependent on the application of neonicotinoid insecticides. Neonicotinoids act primarily by impairing the function of the nicotinic acetylcholine receptors of the nervous system. These compounds also target specific organs (e.g.

Delivery of short hairpin RNA in the neotropical brown stink bug, Euschistus heros, using a composite nanomaterial

Pesticide Biochemistry and Physiology, 2021
The response of insects to orally delivered double-stranded RNA ranges widely among taxa studied to date. Long dsRNA does elicit a response in stink bugs but the dose required to achieve an effect is relatively high compared to other insects such Colorado potato beetle or western corn rootworm. Improving the delivery of dsRNA to stink bugs will improve

Annotation of transposable elements in the transcriptome of the Neotropical brown stink bug Euschistus heros and its chromosomal distribution

Molecular Genetics and Genomics, 2023
Transposable elements (TEs) are DNA sequences capable of moving within the genome. Their distribution is very dynamic among organisms, and despite advances, there are still gaps in the understanding of the diversity and evolution of TEs in many insect species. In the case of Euschistus heros, considered the main stink bug in the soybean crop in Brazil,

Euschistus heros (Neotropical brown stink bug).

2021
Abstract Euschistus heros feeds on several crop plants, especially soyabean. Although it is known as the Neotropical stink bug, there is no clear information about its native range. E. heros is not included in any lists of Euschistus species indigenous to South America (e.g., Grazia, 1987; Martins and Campos, 2006) so it is presumed ...

Imidacloprid resistance in the Neotropical brown stink bug Euschistus heros: selection and fitness costs

Journal of Pest Science, 2018
Neonicotinoid insecticides (e.g., imidacloprid) are some of the most prevalent tools used to control hemipterans that attack soybean crops worldwide. However, the emergence of neonicotinoid-resistant strains of phytosuccivorous soybean pests, such as the Neotropical brown stink bug Euschistus heros, has posed a challenge to the sustainable use of these

Parental RNA interference as a tool to study genes involved in rostrum development in the Neotropical brown stink bug, Euschistus heros

Journal of Insect Physiology, 2021
In insects, the identity of body segments is controlled by homeotic genes and the knockdown of these genes during embryogenesis can lead to an abnormal development and/or atypical phenotypes. The main goal of this study was to investigate the involvement of labial (lab), deformed (dfd), sex comb reduced (scr), extradenticle (exd) and proboscipedia (pb)

Field responses of stink bugs to the natural and synthetic pheromone of the Neotropical brown stink bug, Euschistus heros (Heteroptera: Pentatomidae)

Physiological Entomology, 1998
Abstract.The synthetic racemic mixture of methyl 2,6,10‐trimethyltridecanoate, a component of the male produced pheromone of Euschistus heros (F.) (Heteroptera, Pentatomidae), was attractive to pentatomid species in a field test, using homemade pheromone trap designs. The pentatomid
