“…F. oxysporum and plant secondary metabolites/essential oils contain similar kind of organic chemical constituents with larvicidal, pupicidal and adulticidal activities against mosquitoes [4,5,24]. This study also found that, the crude secondary metabolites had lower toxicity against E. eugeniae (non-targeted) compared to the synthetic chemicals.…”

Background The fungal toxin acts as effective, low-cost chemical substances for pest control worldwide and also an alternative to synthetic insecticides. This study assessed the larvicidal potential of Metarhizium anisopliae fungi derived metabolites against Aedes aegypti, Anopheles stephensi, Culex quinquefasciatus and non-targeted organisms at 24hr post treatment. Method Isolation of entomopathogenic fungi M. anisopliae from natural traps confirmed by using 18s rDNA biotechnological tools. Crude extracts from M. anisopliae solvent extraction and their secondary metabolites were bio-assayed following WHO standard procedures against Ae. aegypti, An. stephensi and Cx. quinquefasciatus, Artemia nauplii, Eudrilus eugeniae, and Solanum lycopersicum after 24 hr exposure. Histopathological analysis of E. eugeniae treated with fungi metabolites toxicity compared to those treated with Monocrotophos after 24hrpost-treatment. M. anisopliae metabolites were characterized using GC-MS and FT-IR analysis. Results The larvicidal activity was recorded in highest concentration of 75μg/ml, with 85%, 97% and 89% mortality in Ae. aegypti, An. stephensi and Cx. quinquefasciatus respectively. M. anisopliae metabolites produced LC 50 values in Ae. aegypti, 59.83μg/ml, in An. stephensi,

“…Nicolson. leaf prepared with different solvents, an optimum toxicity is shown by ethyl acetate fraction with LC 50 value of 1.02 ppm followed by methanol (1.13 ppm), ethyl acetate (1.81 ppm), and hexane (2.34 ppm) fractions (Pratheeba et al 2019) against C. quinquefasciatus vector. Dioncophylline A, isolated from the Triphyophyllum peltatum Airy Shaw has a strong larvicidal activity towards A. stephensi with LC 50 value of 1.12 ppm (Francois et al 1996).…”

“…Recently, plant-derived silver nanoparticles have also emerged as an alternative tool and received extraordinary attention as potent larvicidal agents in recent past (Santhosh et al 2015). Silver nanoparticles have been synthesized using Annona reticulata Linnaeus (Parthiban et al 2019), Chasmanthera dependens Hochst (Aina et al 2019), Ceropegia bulbosa Roxburgh (Vetrivel et al 2019), Piper longum Linnaeus (Yadav et al 2019), Cullen corylifolium Linnaeus (Saini et al 2019), Curcuma zedoaria Roscoe (Sutthanont et al 2019), Naringi crenulata Roxburgh (Pratheeba et al 2019), and Avicennia marina Forsskål (Barnawi et al 2019); they exhibit tremendous larvicidal potential against various mosquito vectors. Herbal silver nanoparticles have several advantages over the chemically synthesized silver nanoparticles like eco-friendly, cost-effective, single-step synthesis, and an easy control of crystal growth, and also, they are non-toxic and safe to handle (Iravani 2011; Salam et al 2012;Shah et al 2016;Benelli 2016a;Das et al 2017;Murugan et al 2017).…”

Mosquitoes spread several life-threatening diseases such as malaria, filaria, dengue, Japanese encephalitis, West Nile fever, chikungunya, and yellow fever and are associated with millions of deaths every year across the world. However, insecticides of synthetic origin are conventionally used for controlling various vector-borne diseases but they have various associated drawbacks like impact on non-targeted species, negative effects on the environment, and development of resistance in vector species by alteration of the target site. Plant extracts, phytochemicals, and their nanoformulations can serve as ovipositional attractants, insect growth regulators, larvicides, and repellents with least effects on the environment. Such plant-derived products exhibit broad-spectrum resistance against various mosquito species and are relatively cheaper, environmentally safer, biodegradable, easily accessible, and are non-toxic to non-targeted organisms. Therefore, in this review article, the current knowledge of phytochemical sources exhibiting larvicidal activity and their variations in response to solvents used for their extraction is underlined. Also, different methods such as physical, chemical, and biological for silver nanoparticle (AgNPs) synthesis, their mechanism of synthesis using plant extract, their potent larvicidal activity, and the possible mechanism by which these particles kill mosquito larvae are discussed. In addition, constraints related to commercialization of nanoherbal products at government and academic or research level and barriers from laboratory experiments to field trial have also been discussed. This comprehensive information can be gainfully employed for the development of herbal larvicidal formulations and nanopesticides against insecticide-resistant vector species in the near future.

“…Insects communicate with their environment using biological signals such as pheromones, plant volatiles and animal odours (Ronderos and Smith 2009;Pratheeba et al 2019) (Benton et al 2009). Among insect species, odour is utilized to detect food (Foster and Hancock 1994), nd a host (Takken 1991), complete the mating process (Cabrera and Jaffe 2007), complete the oviposition process (Bentley and Day 1989), and recognize predators (De Bruyne and Baker 2008).…”

Emodin, a chemical isolated from Aspergillus terreus, was studied using chromatographic and spectroscopic methods and compound purity (96%) was assessed by TLC. Furthermore, high larvicidal activity against Aedes aegypti-AeA (LC 50 5.08 and LC 90 8.23 mg.L − 1 ), Culex quinquefasciatus-CuQ (7.13 and 12.01 mg.L − 1 ), and Anopheles stephensi-AnS larvae (6.40 and 15.24 mg.L − 1 ) was recorded. The rst isolated fraction showed higher pupicidal activity against AeA (0.349 and 0.872 mg.L − 1 ). Most emodintreated larvae (ETL) involutate variations in acetylcholine esterase, α and β-carboxylesterases, and phosphatase activities in the 4th instar, indicating intrinsic differences in their biochemical changes. ETL had numerous altered tissues, including muscle, gastric caeca, hindgut, midgut, nerve ganglia, and midgut epithelium. Acute toxicity of emodin against brine shrimp Artemia nauplii (154.0 and 184.5 mg.L − 1 ) and the zebra sh Danio rerio (less toxicity observed) was evaluated. In docking studies, Emodin interacted well with odorant-binding-proteins of AeA, AnS, and CuQ with docking scores of -8.89, -6.53, and − 8.09 kcal/mole, respectively. Therefore, A. terreus is likely to be effective against mosquito larvicides.
