Abstract:
... Capture strategies for the brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae), are challenging. Here we developed and evaluated a multimodal trap which combines visual and olfactory stimuli. Visual stimuli consisted of LEDs emitting UV-A and visible light. Olfactory stimuli were comprised of the synthetic aggregation pheromone and odours from trapped H. halys individuals. Stin ...

Abstract:
... Here we report the first detection of Halyomorpha halys (Stål, 1855) in Bordeaux vineyards. The species is native to Eastern Asia and was introduced to France in 2012. Halyomorpha halys is highly polyphagous and causes significant damage to various crops, including grapevines. From 2018 to 2020, Pentatomidae species were collected in vineyards in the Bordeaux region. In 2020, the first nymphs and ...

Abstract:
... Halyomorpha halys (Stål, 1855) (Hemiptera: Pentatomidae), the brown marmorated stink bug, is an invasive pentatomid native to East-Asia, and introduced worldwide in recent times. It is a polyphagous pest with approximately 300 host plants, which, due to its plasticity, reproductive and feeding behavior, long-distance flight, and walking as well as human-mediated dispersal ability, is able to cause ...

Abstract:
... The egg parasitoids Trissolcus japonicus (Ashmead) and Trissolcus mitsukurii (Ashmead) (Hymenoptera: Scelionidae) are the most effective biocontrol agents of the invasive agricultural pest Halyomorpha halys (Stål) (Heteroptera: Pentatomidae) in its native range (east Asia). Trissolcus japonicus and T. mitsukurii are sympatric in the native areas. In northern Italy, where H. halys is a major pest o ...

Abstract:
... Olives ripen in the late autumn and represent a good source of nutrients that Halyomorpha halys uses to prepare for diapause. This is the first study to investigate the impact of H. halys infestation on the phenolic response and olive fruit quality in the pierced tissue of damaged fruits and in the non-pierced part of damaged fruits of ‘Istrska belica’ and ‘Pendolino’ cultivars. Both total phenoli ...
... We report the first large-scale augmentative biological control project carried out in Europe against Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) using the native egg parasitoid Anastatus bifasciatus (Geoffroy) (Hymenoptera: Eupelmidae). During summer 2020, a total of 325,000 adults of A. bifasciatus were released at a rate of 1000 individuals/ha of orchard in 11 sites in Trentino-Alto Adig ...
... Odorant-binding proteins (OBPs) play essential roles in the functioning of insect peripheral olfactory systems. To fully understand the olfactory roles of OBPs in Halyomorpha halys, an important invasive pest found worldwide, we studied the expression and functional characterization of five OBP-associated genes from H. halys that are clustered in the genome. The tissue distribution of the OBP gene ...

... During field surveys in Georgia, in the 2019 and 2020 growing seasons, we investigated hazelnut orchards in four regions of Georgia: Achara, Guria, Samegrelo and Kakheti for Brown Marmorated Stink Bug (BMSB) – Halyomorpha halys (Stål)(Hemiptera: Pentatomidae). Additionally, we conducted surveys in apple and peach orchards in the Kartli and Kakheti regions to find out if there was damage caused by ...

Abstract:
... The invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), has disrupted integrated pest management programs in agroecosystems including tree fruit in North America and several other regions worldwide. While the toolbox for managing the pest continues to grow, it has not yet been determined if feeding or oviposition by H. halys onto orchard or forest trees induces ...
... BACKGROUND: The brown marmorated stink bug (BMSB), Halyomorpha halys, has caused significant agricultural damage to numerous hosts, so agricultural producers seek to limit its spread. Where established, BMSB can also cause substantial urban and commercial disturbance, as overwintering adults may seek refuge inside dwellings, covered spaces, vehicles, and consignments. Phytosanitary authorities are ...

Abstract:
... The invasive stink bug Halyomorpha halys, native to east Asia, is a severe agricultural pest of worldwide importance and biocontrol is a promising method for its long-term management. The two Asian egg parasitoids Trissolcus japonicus and Trissolcus mitsukurii are considered to be effective candidates as biological control agents. These species can co-occur in the same habitats and interspecific c ...

Abstract:
... Apple is one of the most important economic fruit crops in the world. Despite all the strategies of integrated pest management (IPM), insecticides are still frequently used in its cultivation. In addition, pest phenology is extremely influenced by changing climatic conditions. The frequent spread of invasive species, unexpected pest outbreaks, and the development of additional generations are some ...

Abstract:
... Retrospective host range testing is essential for understanding the physiological host range of introduced biological control agents (BCAs) and updating forecasts of non-target risks. It is especially important to conduct this work if there was no host range testing prior to release of the agent. Trissolcus basalis Wollaston was released in New Zealand in 1949 against green vegetable bug (Nezara v ...
... The invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is an agricultural and nuisance pest in Georgia and Alabama, USA. Natural enemies may provide significant suppression of the brown marmorated stink bug, and sentinel egg masses are deployed commonly on plants in the field to measure their effects. The objective of this study was to evaluate the effect of d ...

... Many animals, including insects, need to solve the problem of self-righting if inverted and substrate is one understudied factor that could affect righting ability. In this study we ask the questions, how does Halyomorpha halys self-right and does variation in substrate affect self-righting? To address our questions we used four substrates with different features and filmed H. halys righting respo ...

Abstract:
... The brown marmorated stink bug (BMSB), Halyomorpha halys Stål, is an invasive species and a polyphagous pest. BMSB feeding activity was suspected to be responsible for olive damage. To evaluate the effect of feeding damage from adults and nymphs of BMSB, 30 rearing sleeves were positioned in an olive grove, at an early stage of drupe development. The individuals were kept in the rearing sleeves fo ...

Abstract:
... Halyomorpha halys (Stål, 1855) is an invasive agricultural pest in North America and Europe. Most of the information on H. halys predators in invaded areas comes from North America. This work focused on the molecular identification of arthropod predator species capable of feeding on H. halys in northern Italy. Predatory arthropods were collected in the field in four urban parks using the tree‐beat ...
