Multi‐Omics Profiling of the Scaphoideus titanus Yeast‐Like Symbiont Guides the Bioinformatic Discovery of Related Fungal Symbioses in Insects

open access: yesEnvironmental Microbiology, Volume 28, Issue 7, July 2026.
Genomic, proteomic and phylogenetic analyses of the obligate yeast‐like symbiont (YLS) associated with Scaphoideus titanus revealed retained metabolic flexibility and a monophyletic origin of insect‐associated YLSs within a free‐living fungal lineage. A novel computational pipeline was used to mine NCBI transcriptomic data and identified new candidate ...

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

open access: yesPest Management Science, Volume 82, Issue 6, Page 5184-5194, June 2026.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 436-452, May 2026.
Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 598-620, May 2026.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

Characterization of the complete mitochondrial genome of Sogatella kolophon (Hemiptera: Delphacidae)

open access: yesMitochondrial DNA. Part B. Resources, 2021
In this study, we sequenced and annotated the complete mitochondrial genome of Sogatella kolophon (Kirkaldy) (Hemiptera: Delphacidae). The mitogenome was 16,708 bp in length, containing 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes and a ...

‘Candidatus Phytoplasma solani’: From infection to all‐round characterisation of distinct tuf‐type strains with different virulence in tomato plants

open access: yesAnnals of Applied Biology, Volume 188, Issue 2, Page 480-494, March 2026.
‘Candidatus Phytoplasma (Ca. P.) solani’ is associated with bois noir (BN) of grapevine and stolbur of solanaceous plants and is primarily transmitted by Hyalesthes obsoletus Signoret. Four tuf‐a and five tuf‐b1 ‘Ca. P. solani’ strains were transmitted to tomato plants (cv. Micro‐Tom) by using bait‐plants and by capturing H.

A new record of the genus Ecdelphax (Hemiptera: Auchenorrhyncha: Delphacidae) from the Korean Peninsula with a key to the species

open access: yesJournal of Asia-Pacific Biodiversity, 2023
The delphacid species, Ecdelphax tortilis (Kouh, 1982), is recorded from the Korean Peninsula for the first time. The morphological information such as diagnosis and redescription of male habitus and genitalia are presented with photographs, and a key to

Climate Change Can Generate Enemy‐Free Space for Crop‐Feeding Herbivores

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
Magnitude and direction of change in parasitoid pressure for 14 agricultural pests subject to climate‐driven distributional shifts. Pests are organized per increasing parasitoid pressure under current climatic conditions (X axis). Bubble size is reflective of the (absolute) area affected by a given pest under a given scenario.
