Article Abstract

Currently, there is a growing preference for eco-friendly bioinsecticides over chemical insecticides due to their safety. Plant extracts have emerged as a promising solution for this purpose. Therefore, this study aimed to evaluate the insecticidal effectiveness of extract against two key pests of rose aphid () and pistachio psylla (). Significant compounds were identified using GC-MS and MALDI-TOF MS. Three bioassay methods were employed to assess the extract's insecticidal potential, and its cytotoxicity was tested on HEK293 cells. Results revealed that the highest insecticidal efficacy occurred at a concentration of 20 mg/mL after a 72 h exposure. The contact bioassay method displayed greater efficiency against than , while the oral bioassay demonstrated the highest efficiency against . The extract also acted as a feeding deterrent, with indices of 77.47 ± 7.98 % and 87.98 ± 3.84 % for and , respectively. Furthermore, the insecticidal potency of the extract was assessed, resulting in LC values of 3.58 mg/mL and 6.77 mg/mL for the contact bioassay, and 0.87 mg/mL and 0.61 mg/mL for the oral bioassay against and , respectively. Importantly, the extract showed no detrimental cytotoxic effects on the HEK293 cell line within the tested concentration range, indicating its potential safety as a bioinsecticide. Overall, these findings highlight the potential of extract as a promising candidate for further development in pest control.

Background: Stored-product insects (Sitophilus spp., Plodia interpunctella, Sitotroga cerealella) drive substantial postharvest losses and increasingly resist synthetic fumigants. Valeriana wallichii roots yield volatile oils rich in short-chain acids and sesquiterpenes.

The limited water solubility and environmental instability of natural pesticidal compounds impede their broader agricultural use. This study reports an amphiphile-assisted nanoprecipitation method to imbibe azadirachtin-rich neem seed extract (NSE) within a glycine carrier matrix, yielding a stable nanocomposite biopesticide. The formulation, prepared using polyoxyethylene sorbitan monooleate as a stabilizer and glycine as the matrix former, followed by lyophilization, exhibited a hydrodynamic diameter of ∼8 nm when redispersed in water.

Zoonotic malaria risk at human-wildlife-environment interfaces requires surveillance that integrates signals from reservoirs, vectors and the environment. We coupled a drone-based environmental DNA (eDNA) canopy swabbing approach with portable quantitative PCR (qPCR) to detect DNA in situ during a 24-h field exercise in the Amazon rainforest. Drone-lowered sterile swabs into the canopy, which were then extracted and subjected to a multiplex pan- assay targeting five human-infecting species (limit of detection 0.

Local anesthesia is essential for most dental procedures, but its parenteral administration is often painful. Topical anesthetics are commonly used to minimize local anesthesia pain; however, commercial formulations fail to fully prevent the discomfort of local anesthetic injection. We developed and characterized a novel lidocaine and epinephrine co-loaded liquid crystalline precursor system (LCPS) for topical anesthesia.

The increasing environmental and health concerns about synthetic pesticides have compelled researchers to investigate more sustainable, plant-based substitutes for pest management. Due to their unique modes of action and biodegradability, essential oils (EOs) represent effective bio-pesticides. This study examines the biological activities of (Asteraceae) EO (AVEO) against Keifer (Eriophyidae), a destructive gall mite on (Fabaceae), using fumigation, contact toxicity, and repellency assays for the first time.
