Alternative Food for Litter‐Inhabiting Predators Decreases Thrips Densities and Above‐Ground Plant Damage

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We studied predatory soil mites that control the thrips Frankliniella occidentalis. Thrips densities were significantly reduced by the predator Cosmolaelaps sabelisi. It presumably feeds on prepupae and pupae in the soil and on larvae aboveground.

Attractiveness of Melon Genotypes to Whitefly (Bemisia tabaci) Mediated by Foliar Morphological and Biochemical Traits

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This study identifies melon genotypes resistant to Bemisia tabaci by integrating morphological and biochemical leaf traits. Using free‐choice and no‐choice assays, we demonstrate that resistance is primarily mediated by antixenosis. Genotypes CNPH 11‐1071‐43, CNPH 06‐1047‐343, CNPH 13‐1076, and BG MEL 16 significantly reduced whitefly settling and ...

Golden weapons and golden fetters: From the gold standard to the new geopolitics

open access: yesThe Economic History Review, EarlyView.
Abstract This paper explores the historical relationship between monetary regimes, security concerns, and geopolitical tensions, particularly focusing on the role of gold. Throughout history, monetary systems have been deeply intertwined with international state systems and security provisions.

Stability of 3D tunnel face under steady unsaturated seepage coupled multi-layer soil suction head distributions

open access: yesAlexandria Engineering Journal
This paper proposes a new discrete approach for analyzing tunnel face stability in stratified soils under unsaturated seepage conditions. Traditional methods have primarily focused on homogeneous soils, neglecting the spatial variability of unsaturated ...

Arthropod conservation in roadside verges: Unmown refuges outperform mowing equipment changes

open access: yesInsect Conservation and Diversity, EarlyView.
While roadside verges might have potential as connecting corridors for grassland habitats and their inhabitants, roadside mowing negatively impacts grassland arthropod densities. In contrast to unmown refuges, all mowing techniques harmed grassland arthropods, with no significant differences between mowing equipment.

Lethal Effects of the Wild Potato Solanum bulbocastanum on the Planthopper Pentastiridius leporinus, a Vector of Bacterial Pathogens in Potato

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The planthopper Pentastiridius leporinus [Hemiptera: Cixiidae] is a vector of the two plant pathogenic bacteria ‘Candidatus Arsenophonus phytopathogenicus’ and ‘Candidatus Phytoplasma solani’ causing ‘bacterial potato tuber wilt’ in potato.

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...

Entangled Foodways and Livelihood Pathways: Cinnamon, State Interventions, and Everyday Life in Hmong Communities of Northern Vietnam

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT The agroecological practices of ethnic minority farmers in Vietnam's northern uplands are being reshaped by intersecting pressures of land‐use reform, market integration, and state‐backed crop promotion. Among Hmong communities in the south of Lào Cai Province (former Yên Bái Province) cinnamon was once valued primarily for its medicinal ...
