Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

open access: yesPhysiological Entomology, EarlyView.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...

Defense strategies and associated phytohormonal regulation in Brassica plants in response to chewing and sap-sucking insects

open access: yesFrontiers in Plant Science
Plants have evolved distinct defense strategies in response to a diverse range of chewing and sucking insect herbivory. While chewing insect herbivores, exemplified by caterpillars and beetles, cause visible tissue damage and induce jasmonic acid (JA ...

Glyphosate residues in soil alter herbivore‐induced plant volatiles and affect predatory insect behaviour

open access: yesPlant Biology, EarlyView.
Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.

Impact of cultural practices on two‐spotted spider mite (Tetranychus urticae Koch) infestation in tomato cultivation in the Central Rift Valley of Ethiopia

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract The two‐spotted spider mite (TSSM; Tetranychus urticae Koch) is a major pest of tomato (Solanum lycopersicum L.), causing substantial yield and quality losses in Ethiopia and worldwide. The present study evaluated the impact of tomato branch pruning and trellising on TSSM populations and yield in the Central Rift Valley tomato production area ...

Insect‐resistant soybean genotypes accumulate rutin and its O‐methylated derivative narcissin, a more potent flavonol targeting Anticarsia gemmatalis digestive and detoxification enzymes and reducing larval survival

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5921-5933, 15 August 2026.
Abstract BACKGROUND Soybean underpins Brazil's agricultural, yet its sustainability is threatened by lepidopteran pests such as Anticarsia gemmatalis. Although insect‐resistant cultivars have long been associated with the constitutive accumulation of quercetin‐derived flavonols, the biochemical mechanisms underlying this resistance remain poorly ...

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

open access: yesPest Management Science, Volume 82, Issue 8, Page 7794-7808, August 2026.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...

Testing optimal defense theory: Root resistance selection in chicory (Cichorium intybus) reduces foliar defense and alters aphid performance and feeding behavior

open access: yesPest Management Science, Volume 82, Issue 8, Page 7951-7960, August 2026.
Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...

Efficacy of Amblyseius swirskii, and Neoseiulus californicus (Acari: Phytoseiidae) and acaricides in controlling some pests on sweet pepper in greenhouses

open access: yesPersian Journal of Acarology
In Egypt, serious piercing-sucking pests such as the western flower thrips, Frankliniella occidentalis, white fly, Bemisia tabaci, the broad mite, Polyphagotarsonemus latus, and the two-spotted spider mite, Tetranychus urticae cause significant yield ...

Diversity of flies visiting and pollinating flowers of the Southern African genus Riocreuxia (Apocynaceae: Ceropegieae, Anisotominae)

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract The subtribe Stapeliinae (Apocynaceae: Asclepiadoideae) contains ca. 720 species and, with fly pollination being ubiquitous in the group, appears to have diversified without shifts between major groups of pollinators. In contrast, the sister subtribe Anisotominae, which only has ca.

Searching for the beasts in the archive as methodological praxis

open access: yesGeographical Research, Volume 64, Issue 3, August 2026.
This article offers searching for the beasts in the archive as a methodological tool available to researchers invested in both anticolonialism and antianthropocentrism. By focusing on three basic units of reference—categories, histories, and borders—the article shows how searching for the beasts unsettles some taken‐for‐granted assumptions that ...
