Prolonged Sublethal Imidacloprid Exposure Reduces the Functional Response and Searching Efficiency of Orius similis Against Frankliniella occidentalis

ABSTRACT Neonicotinoid residues can compromise biological control in integrated pest management, yet the role of exposure duration is rarely quantified for predatory bugs. Here, we compared short‐term (24 h) and long‐term sublethal exposure to imidacloprid (LC 10 and LC 20 ) on t...

Partner of bursicon Regulates Pheromone Gland Development and Sex Pheromone Biosynthesis in Helicoverpa armigera

Bursicon, a heterodimeric neuropeptide composed of Burs-α and its binding subunit Partner of bursicon (Pburs), is primarily known to regulate insect cuticle tanning and also participates in wing expansion, reproduction and immunity. Pburs is highly expressed during pheromone glan...

Molecular Characterization of a Novel Monopartite Begomovirus Infecting Weeds and Important Crops in Yunnan, China

The genus Begomovirus constitutes a group of devastating plant viruses causing significant economic losses in the production of agricultural crops. In the present study, conducted in Yunnan province, China, a novel monopartite begomovirus was identified from Bidens pilosa, Crasso...

Genetic Diversity and Phylogeny of Chilli Veinal Mottle Virus in Yunnan Tobacco-Planting Regions Based on the CP Gene

Chilli veinal mottle virus (ChiVMV, Potyvirus capsivenamaculae) can infect various Solanaceae crops, causing a decrease in yield and quality. In recent years, ChiVMV has become one of the most prevalent viruses affecting tobacco production, but its diversity and genetic structure...

Biostimulatory Effect of 3-Acetonyl-3-Hydroxyoxindole on the Growth and Secondary Metabolites of Khaya senegalensis: UPLC–MS/MS Profiling and Molecular Docking Insights

Developing sustainable agricultural biostimulants that simultaneously optimize vegetative growth and specialized metabolic pathways is critical for maximizing plant growth, photosynthetic efficiency, and metabolome reprogramming. In this study, for the first time, the effects of...

Genetic architecture of node-specific leaf length and candidate gene identification in maize revealed by a temperate–tropical multiparental population

Abstract Background Optimizing leaf morphology is essential for improving maize plant architecture, plant density tolerance, and yield. Leaf length is a key agronomic trait controlled by complex genetic mechanisms. In this study, upper leaf length (ULL), ear leaf length (ELL) and...

First Report of Leaf Rot on Chinese Chive ( Allium tuberosum Rottler ex Spreng.) Caused by Phytophthora heterospora in Yunnan Province, China

Chinese chives (Allium tuberosum Rottler ex Spreng.), an economically important aromatic vegetable, are widely cultivated worldwide. In May 2025, a severe leaf rot disease was observed on Chinese chives in Mile (24.45°N, 103.4°E), Yunnan Province, China. Following consecutive day...
