Abstract Entomopathogenic fungi are the most effective control remedy against a wide range of medical and agricultural important pests. The present study aimed to isolate, identify, assess virulence Metarhizium rileyi Spodoptera litura frugiperda pupae under soil conditions. biotechnological methods were used identify isolate as M. . fungal conidial pathogenicity (2.0 × 10 7 , 2.0 8 9 11 conidia/mL −1 ) was tested prepupae S. at 3, 6, 9, 12 days after treatments. Additionally, artificial soil‐conidial assay performed on nontarget species earthworm Eudrilus eugeniae using conidia. results showed that caused significant mortality rates in (61‐90%), more susceptible than (46%–73%) day posttreatment. LC 50 90 3.4 14 –9.9 17 6.6 5 –4.6 respectively. conidia did not exhibit any sublethal effect adult stage E. Artemia salina following 12‐day treatment period. Moreover, histopathological evaluation no discernible harm observed gut tissues including lumen epithelial cells, well muscles, setae, nucleus, mitochondria, coelom. findings provide clear evidence can be foundation for development bio‐insecticides combat

The jute hairy caterpillar, Spilosoma obliqua (Lepidoptera: Erebidae) is considered as one of the major threats to cultivation. best eco-friendly methods combat these pests involve administration nano-biopesticides, a successful alternative toxic chemicals. In this study, nano-biopesticide formulation containing green synthesized silver nanoparticles (Ag NPs) using Ocimum sanctum leaf extract has been proposed. characterization studies confirmed significant interactions between Ag NPs and bioactive components in formulation. comparative analysis aforementioned larval mortality showed better responses rather than crude (pure) extract. LC50 values were calculated both for pure after 24, 48 72 h treatment. was found exhibit lowest much promising value 93.21 ppm, 23.38 5.96 ppm relative that 1590.74 459.30 102.68 respectively synergistic can be associated with its greater effectiveness toxicant larvae caterpillar compared mere extract, thereby, demonstrating greener safer method effective pest management.

Abstract Despite continuous efforts to control mosquito populations and disease vectors, they remain prevalent globally pose significant health risks. Botanicals have garnered increasing attention as alternatives synthetic insecticides due their broad‐spectrum insecticidal properties, biodegradability, environmental compatibility. This study aimed evaluate the larvicidal efficacy of Solanum incanum Soxhlet extracts using various solvents. Additionally, we conducted a phytochemical analysis methanol gas chromatography–mass spectrometry (GC–MS) performed molecular docking studies. The extract S. demonstrated activity, with LC 50 values 266.75, 214.52, 90.15 μg/mL at 24, 48, 72 hours post‐treatment, respectively. GC–MS identified several compounds in extract, trans‐9‐Octadecenoic acid, pentyl ester (17.99%) propanoic 2‐(3‐acetoxy‐4,4,14‐trimethylandrost‐8‐en‐17‐yl) (14.42%) being most abundant. exhibited highest phenolic content, 1.44 mg GAE/g. IC50 for DPPH assay were 1.69 mg/mL ethyl acetate 6.7 extract. Furthermore, supported findings, emerging top compound all targets tested, including AChE (−9.4 kcal/mol), GABA‐T (−8 ATPase (−7.9 kcal/mol). These results provide valuable insights into potential application development bioinsecticides.

ABSTRACT Mosquitoes act as biological carriers spreading numerous vector borne diseases globally. The present research aimed to study the effect of essential oils (EOs) from Pentanema indicum (L.) Y. Ling and Chromolaena odorata R.M. King & H. Rob against Aedes aegypti , Anopheles stephensi Culex quinquefasciatus mosquitoes. Concentrations 3.125, 6.25, 12.5 25 50 ppm were tested for their mosquitocidal properties. oil (EO) P. demonstrated promising ovicidal activity, achieving 100% efficacy Ae. Cx. 76% An. at a concentration within 24 h. Similarly, C. exhibited significant activity higher concentrations, with rates 72% 79% 64% 300 after 72 In terms larvicidal showed potent toxicity LC values 4.28 14.01 5.47 . Additionally, considerable mosquito 95.28 98.95 89.05 However, no pupicidal was observed both EOs. GC–MS analysis identified β‐Pinene (14.31%), D‐Limonene (13.48%) Caryophyllene (25.48%) main components in EO contained α‐Pinene (12.10%), Geijerene (11.62%) (10.64%) primary components; probably these compounds responsible activities. Toxicity studies indicated that EOs plants had adverse effects on natural predators. then formulated field application laboratory setting; they without harming This suggests offer an effective alternative synthetic pesticides.

Abstract By disseminating viruses and parasites like malaria dengue, mosquitoes contribute to problems with global health. Unfortunately, resistance high cost make the current insecticide-based control methods only moderately effective. In order mosquito-borne diseases, scalable, long-lasting, affordable strategies are required. At present, entomopathogenic fungi (EPF) being considered as a naturally occurring vector agent. Spores metabolites of EPF have been confirmed cause histopathological toxicity in at their larval stage. The ability kill mosquito larvae has also made them increasingly desirable recent years for use biological synthesis silver nanoparticles. extremely low concentrations, fungi-based nanoparticles an effective larvicidal Likewise, several nematophagous suppress pest act natural biocontrol agents. Nematophagous exhibit over 50 nematicidal metabolites, which can serve precursors production insecticidal properties. However, there limited number studies conducted on this subject. Therefore, purpose review is emphasize significance insect management so that potential application these beneficial organisms be used fullest.

Plant-derived compound emerges as alternatives to integrated control of Aedes aegypti, the main transmitter Chikungunya, Dengue, Zika virus. The effects Magonia pubescens A. St.-Hill extracts on Ae. aegypti larval development were assessed. Four in vitro assays analysed insecticidal potential (% mortality) aqueous and ethanolic (EE) leaves seeds. using UHPLC-MS/MS. By comparing data from three databases, 12 compounds different classes identified EE, including coumarins, phenolic acids, polyphenols, flavonoids. EE was most effective, with an LC90 0.262 mg/mL. Morphological alterations observed larvae exposed extracts, showing epithelial walls extravasation intestinal contents. These findings highlight effectiveness M. extract a bioinsecticidal agent against larvae.
