Non-targeted insecticidal stress on the Neotropical brown stink bug Euschistus heros
Crop Protection, 2016 Abstract Lethal and sublethal insecticide effects on non-targeted pest species are frequently neglected but have potential consequences for pest management and secondary pest outbreaks. Here, the lethal and demographic effects of four soybean insecticides (chlorantraniliprole, deltamethrin, pyriproxyfen, and spinosad, which are used against ...

Stimulatory male volatiles for the Neotropical brown stink bug, Euschistus heros (F.) (Heteroptera: Pentatomidae) [PDF]
Neotropical Entomology, 2003 Volatiles compounds collected from the male Neotropical brown stink bug, Euschistus heros (F.), a serious Central and South American soybean pest, have been reevaluated. The proportion of three methyl esters is found to be quite different from previous study.

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.

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).

Insecticide resistance to endosulfan, monocrotophos and metamidophos in the neotropical brown stink bug, Euschistus heros (F.) [PDF]
Neotropical Entomology, 2001 The Neotropical brown stink bug, Euschistus heros (F.), is usually controlled by organophosphate (OP) and cyclodiene (endosulfan) insecticides. Some unsuccessful control cases lead us to search for resistance to these insecticides in E. heros, the most common stink bug in the soybean growing regions of Parana State, Sao Paulo State and Central Region ...

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,

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

Euschistus heros (Neotropical brown stink bug).
2021Abstract 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 ...

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)

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
