Population Genomics of the Neotropical Brown Stink Bug, Euschistus heros: The Most Important Emerging Insect Pest to Soybean in Brazil [PDF]

Frontiers in Genetics, 2019
Recent changes in soybean management like the adoption of transgenic crops and no-till farming, in addition to the expansion of cultivated areas into new virgin frontiers, are some of the hypotheses that can explain the rise of secondary pests, such as ...

Oviposition preference of the neotropical brown stink bug Euschistus heros on artificial substrates of different colors [PDF]

Ciência Rural, 2013
This study aimed to evaluate the oviposition preference of the Neotropical brown stink bug, Euschistus heros (F.) on artificial substrates of different colors (felt woven). For this, ten pairs of stink bugs were transferred into plastic pots.

Can Metarhizium anisopliae Reduce the Feeding of the Neotropical Brown Stink Bug, Euschistus heros (Fabricius, 1798), and Its Damage to Soybean Seeds? [PDF]

Journal of Fungi
The fungus Metarhizium anisopliae is under development as a bioinsecticide for Euschistus heros. To further elucidate the effect of this fungus on E. heros behavior, we monitored the feeding activities of adults treated with the fungus at 1 × 108 conidia

The Frequency and Spread of a GABA-Gated Chloride Channel Target-Site Mutation and Its Impact on the Efficacy of Ethiprole Against Neotropical Brown Stink Bug, Euschistus heros (Hemiptera: Pentatomidae) [PDF]

Insects
The Neotropical brown stink bug (NBSB), Euschistus heros, is the most prevalent sucking soybean pest in Brazil, and control of it largely relies on the application of synthetic insecticides such as ethiprole, a phenylpyrazole insecticide targeting GABA ...

The reunion of two lineages of the Neotropical brown stink bug on soybean lands in the heart of Brazil. [PDF]

Sci Rep, 2018
AbstractThe rapid pace of conversion of natural areas to agricultural systems is highly concerning, and the consequences for conservation and pest management are not yet fully understood. We examined mitochondrial (COI and Cytb) and nuclear (ITS1) gene regions of 21 populations of the stink bug Euschistus heros, to investigate the genetic diversity ...

Characterization and Comparison of Intestinal Bacterial Microbiomes of Euschistus heros and Piezodorus guildinii Collected in Brazil and the United States [PDF]

Frontiers in Microbiology, 2021
Background: Herbivorous insects are one of the main biological threats to crops. One such group of insects, stink bugs, do not eat large amounts of tissue when feeding on soybean, but are damaging to the quality of the seed yield as they feed on green ...

Neotropical brown stink bug (Euschistus heros) resistance to methamidophos in Paraná, Brazil [PDF]

Pesquisa Agropecuaria Brasileira, 2010
The objective of this work was to evaluate the soybean neotropical brown stink bug (Euschistus heros) resistance to methamidophos through laboratory bioassays. Bioassays were carried out using populations of adults and nymphs of Euschistus heros in the last instar collected in soybean crops in Paraná State. Highest frequencies of genotypes resistant to

Electropenetrography Monitoring of the Neotropical Brown-Stink Bug (Hemiptera: Pentatomidae) on Soybean Pods: An Electrical Penetration Graph-Histology Analysis. [PDF]

J Insect Sci, 2018
The Neotropical brown-stink bug Euschistus heros (F.) (Hemiptera: Pentatomidae) is the most important pest damaging soybean in the Neotropics, the world largest production area. The alternating current-direct current (AC-DC) electropenetrography (EPG) technology was used to develop an EPG waveform library of adult females feeding on soybean (Glycine ...

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.

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 ...
