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...

First report of cowpea mild mottle virus naturally infecting Salvia miltiorrhiza in China

Salvia miltiorrhiza Bge, also called Danshen, is a perennial Chinese herbal medicine belonging to the family Lamiaceae and has been used for the treatment of cardiovascular and cerebrovascular diseases (Jung et al. 2020). Henan province is one of the main and genuine production a...

Threshold-window framework reveals management-sensitive controls of CH4 and N2O emissions in flooded rice

Rice paddies are major sources of methane (CH 4 ) and nitrous oxide (N 2 O), yet co-managing water and nitrogen (N) to limit both gases remains challenging because emissions arise from non-linear interactions among multiple drivers. We combined a two-year field experiment in subt...

Attractancy Potentialof Terpinen-4-ol against Bactrocera dorsalis (Hendel) and Its SynergisticAttractant Effects Evaluation

Abstract Bactrocera dorsalis is a major fruit and vegetable pest with limited effective attractants. Our previous work identified Melaleuca quinquenervia essential oil (MQEO) as a strong attractant. Guided by an olfactory transcriptome- and molecular docking-informed screening st...

2',4′-dimethylacetophenone from Streptomyces roseofulvus St29 suppresses tobacco bacterial wilt by targeting virulence regulation and membrane integrity of Ralstonia solanacearum

Tobacco bacterial wilt, caused by Ralstonia solanacearum , is a destructive soil-borne disease that severely threatens global tobacco production. In this study, fifteen actinobacteria-like strains were isolated from the rhizosphere soil of healthy tobacco plants. Among them, ten...

Developmental Toxicityand Mechanistic Insights intothe Novel Fungicide Fluindapyr in Zebrafish Embryos

Abstract Succinate dehydrogenase inhibitor (SDHI) fungicides pose potential risks to nontarget aquatic organisms. Fluindapyr, a newly registered SDHI fungicide, is likely to enter aquatic environments, yet its toxicity remains largely unexplored. Here, zebrafish (Danio rerio) emb...

Chemical Signaling and Integrated Strategies for Biological Control in Crop Agroecosystems

Food security faces significant challenges due to the growing threat of insect pests and global climate change, making it essential to adopt sustainable agricultural strategies. Plants possess intrinsic defense systems that are activated in response to herbivore attack, including...
