Spatial Distribution of Euschistus heros (F.) (Hemiptera: Pentatomidae) in Soybean

Neotropical Entomology, 2013
Soybean bugs are major crop pests that cause significant reduction in harvest yield and influence grain quality. The aim of this study was to verify the spatial distribution of Euschistus heros (F.) (Hemiptera: Pentatomidae) in conventional and transgenic soybean cultivars.

Histology of Damage Caused by Euschistus heros (F.) Nymphs in Soybean Pods and Seeds

Neotropical Entomology, 2021
The Neotropical brown stink bug, Euschistus heros (F.), feeds on stems, leaves, pods, and seeds of soybean, Glycine max (L.) Merrill. Knowledge of the damage that nymphs at different instars can cause to soybean pods and seeds, as well as efficient histological techniques for locating the salivary sheath are sparse.

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.

Elucidating the pathogenicity of Metarhizium to Euschistus heros (Hemiptera: Pentatomidae) eggs

Journal of Invertebrate Pathology
The ovicidal effect of entomopathogenic fungi and the mechanisms involved are still debated. The hypothesis that the metabolic activity of germinating conidia can cause insect embryos to become unviable without physical penetration has been proposed. Here, we demonstrated that Metarhizium anisopliae and Metarhizium pingshaense (in a different manner ...

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 ...

Prevalence, replication, and tissue-specific localization of Euschistus heros virus (EhV) across life stages of the Neotropical brown stinkbug Euschistus heros (Hemiptera: Pentatomidae)

Journal of Invertebrate Pathology
The Neotropical brown stink bug,Euschistus heros(Hemiptera: Pentatomidae), is a major agricultural pest in Brazilian soybean crops, exhibiting increasing insecticide resistance in field. This study investigates the dynamics ofEuschistus herosvirus (EhV), a multispecies iflavirus, in laboratory populations ofE.

Insecticide susceptibility of Euschistus heros (Heteroptera: Pentatomidae) in Brazil.

Journal of economic entomology, 2009
Euschistus heros (F.) (Heteroptera: Pentatomidae) is the most prevalent stink bug pest in Brazil, and populations can be difficult to manage using organophosphates or endosulfan. Because E. heros is difficult to rear in the laboratory, no baseline insecticide susceptibility data have been published.

Culturable symbionts associated with the reproductive and digestive tissues of the Neotropical brown stinkbug Euschistus heros

Antonie van Leeuwenhoek, 2018
Symbionts are widely distributed in eukaryotes, and potentially affect the physiology, ecology and evolution of their host. Most insects harbour free-living bacteria in their haemocoel and gut lumen, intracellular-living bacteria in a range of tissues or bacteria in host-derived specialized cells. Stinkbugs, as do many arthropods, harbour extracellular

First Record of Euschistus atrox (Westwood) (Hemiptera: Pentatomidae) on Soybean Fields in Brazil: Characterization, Reproductive Traits and Hybridization with Euschistus heros (Fabricius)

Neotropical Entomology
Euschistus heros (Fabricius) (Hemiptera: Pentatomidae) is Brazil's most significant soybean stink bug pest, with outbreaks well-documented across various regions. However, during a collection expedition in soybean crops in Amapá State, Euschistus atrox (Westwood) was identified as the predominant Euschistus species in these areas.
