Insights on the phenology of the Asian longhorned tick (Haemaphysalis longicornis) using stored lipids

Insect Science, Volume 33, Issue 1, Page 396-406, February 2026.
Lipid analysis of field‐collected ticks unveiled a complex population structure and supports the potential for several stages to overwinter. Abstract The seasonality of Haemaphysalis longicornis in the United States comprises overlapping life stages in the spring and summer.

Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission

Advanced Science, Volume 13, Issue 5, 27 January 2026.
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.

Japanese spotted fever with post-infectious encephalitis

IDCases, 2023
Japanese spotted fever (JSF) is a rickettsial disease caused by Rickettsia japonica. To the best of our knowledge, there have only been five reported cases of JSF involving the central nervous system.

Update of the Xylella spp. host plant database – Systematic literature search up to 30 June 2025

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract This scientific report provides an update of the Xylella spp. host plant database, aiming to provide information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp. Upon a mandate of the European Commission, EFSA created and regularly updates a database of host plant species of Xylella spp.

Influence of Plant Genotype on Nodule‐Associated Bacterial Community Composition and Function in Seasonal Field Pea Varieties

Legume Science, Volume 7, Issue 4, December 2025.
ABSTRACT Legume root nodules host symbiotic rhizobia that are essential for nitrogen fixation but also harbor diverse non‐rhizobial taxa that remain poorly characterized. Field pea (Pisum sativum) cultivars adapted to distinct seasonal growth (spring and winter) offer an opportunity to explore whether host genotype influences nodule‐associated ...

High prevalence of Rickettsia spp. in ticks from wild hedgehogs rather than domestic bovine in Jiangsu province, Eastern China

Frontiers in Cellular and Infection Microbiology, 2022
BackgroundSpotted fever group Rickettsia (SFGR), containing various pathogenic Rickettsia spp., poses remarkable negative influences to public health by causing various severe or mild diseases. Information regarding prevalence of SFGR in ticks in Jiangsu

A Comprehensive Study of Biohopanoid Production in Alphaproteobacteria: Biosynthetic, Chemotaxonomical, and Geobiological Implications

Geobiology, Volume 23, Issue 6, November/December 2025.
ABSTRACT Bacteriohopanepolyol derivatives (BHPDs) and dia‐ and catagenetic products formed from these bacterial membrane modifiers are extensively used as biomarkers in molecular ecological and geoscience studies. Some BHPDs can be assigned to specific phylogenetic bacterial groups. With the vastly increasing availability of complete bacterial genomes,

Primary and Secondary Symbionts of Cambodian Cicadellidae and the Role of Parasitisation

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Leafhoppers are key agricultural pests, and their interactions with parasitoids may be influenced by microbial symbionts. In this study, we characterized the bacterial communities of six Cambodian leafhopper species and their parasitoids, finding that while Sulcia dominates leafhopper microbiotas, parasitoids exhibit higher microbial diversity.
