“…Only 5% of pesticides used worldwide are biopesticides, notwithstanding their effectiveness as insecticides ( Kumar et al, 2021 ; Rakshit et al, 2021 ). But biopesticides are growing quickly and are expected to overtake chemical pesticides soon, with an average annual growth rate of 9–20% ( Lahlali et al, 2022 ). This is because biopesticides have unique qualities that make them useful, such as not being harmful to the environment.…”

Biosynthetic metals have attracted global attention because of their safety, affordability, and environmental friendliness. As a consequence, the cell-free filtrate (CFF) of Dill leaf-derived endophytic fungus Aspergillus luchuensis was employed for the extracellularly synthesis silver nanoparticles (AgNPs). A reddish-brown color shift confirmed that AgNPs were successfully produced. The obtained AgNPs were characterized by UV–Vis (ultraviolet–visible spectroscopy), Transmission electron microscopy (TEM), FTIR, EDX, and zeta potential. Results demonstrated the creation of crystalline AgNPs with a spherical shape at 427.81 nm in the UV–Vis spectrum, and size ranged from 16 to 18 nm as observed by TEM. Additionally, the biogenic AgNPs had a promising antibacterial activity versus multidrug-resistant bacteria, notably, S. aureus, E. coli, and S. typhi. The highest growth reduction was recorded in the case of E. coli. Furthermore, the biosynthesized AgNPs demonstrated potent antifungal potential versus a variety of harmful fungi. The maximum growth inhibition was evaluated from A. brasinsilles, followed by C. albicans as compared to cell-free extract and AgNO3. In addition, data revealed that AgNPs possess powerful antioxidant activity, and their ability to scavenge radicals increased from 33.0 to 85.1% with an increment in their concentration from 3.9 to 1,000 μg/mL. Furthermore, data showed that AgNPs displayed high catalytic activity of safranin under light irradiation. The maximum decolorization percentage (100%) was observed after 6 h. Besides, the biosynthesized AgNPs showed high insecticidal potential against 3rd larval instar of Culex pipiens. Taken together, data suggested that endophytic fungus, A. luchuensis, is an attractive candidate as an environmentally sustainable and friendly fungal nanofactory.

“…Essential oils (EOs) and plant extracts include significant natural compounds that can naturally degrade and can therefore be used to effectively control pests and diseases [63]. These natural products are mostly made up of volatile organic compounds (VOCs), which are predominantly from the phenylpropanoid and terpenoid families and have a high vapor pressure at room temperature.…”

Biopesticides are formulations derived from naturally occurring compounds that manage pests through non-toxic and environmentally favorable means. Being living organisms (natural enemies) or products, biopesticides represent less of a risk to the environment and to human health. Biopesticides, classified into three broad classes, are increasingly used in pest control, and include semiochemicals, plant-incorporated protectants (PIPs), and compounds derived from plants and microorganisms. Because of their advantages for the environment, target-specificity, efficacy, biodegradability, and applicability in integrated pest management (IPM) programs, biopesticides are gaining interest. Although biopesticides have seen significant advances in market penetration, they still make up a relatively small fraction of pest management solutions. Over 3000 tons are produced globally per annum, and this number is rising rapidly. In India, biopesticides account for just 4.2% of the country’s total pesticide market. Although the government has promoted the use of biopesticides by including them in several agricultural programs, biopesticides face numerous difficulties at a local level, but are predicted to expand at an astonishing 10% yearly pace. Under the Insecticides Act 1968, the Ministry of Agriculture in India controls the use of pesticides. Among the major biopesticides produced and used in India are Trichoderma, Bacillus thuringiensis, nuclear polyhedrosis virus, and neem-based pesticides.

However, biopesticides are expanding rapidly and are expected to overtake chemical pesticides in the near future at an average annual growth rate of 9-20% [49][50][51][52], due to the unique characteristics of biopesticides that encourage their application, including their non-toxicity to the environment.…”

Mosquitoes, one of the deadliest animals on the planet, cause millions of fatalities each year by transmitting several human illnesses. Phytochemicals are possible biological agents for controlling pests that are harmful to both human and animal health as well as crops. Plants contain a wide range of potential phytochemicals that are target-specific, rapidly biodegradable, and eco-friendly. The potential of leaf extracts of Bougainvillea glabra, Delonix regia, Lantana camara, and Platycladus orientalis against Culex pipiens and microbial agents was evaluated. Acetone extracts had more toxic effects against Cx. pipiens larvae (99.0–100%, 72 h post-treatment), and the LC50 values were 142.8, 189.5, 95.4, and 71.1 for B. glabra, D. regia, L. camara, and P. orientalis, respectively. Plant extracts tested in this study showed high insecticidal and antimicrobial potential. L. camara acetone extract inhibited all the tested microbial isolates. D. regia showed higher antioxidant activity than other plant extracts in scavenging free radicals. GC-MS results showed the acetone extract had a higher number of chemical classes, with more terpene compounds. HPLC analysis showed the presence of flavonoids and phenolic compounds in L. camara and P. orientalis acetone extracts, and Sylimarine and Rutin were the most abundant. ADME analysis of elemene, caryophyllene oxide, caryophyllene, and copaene showed drug-likeness and revealed better gastrointestinal absorption and permeation of the blood-brain barrier by all the tested phytochemicals. Our results confirm that the diversity of phytochemicals found in ornamental plants has promising larvicidal activity and is a safe and effective alternative to chemical insecticides and biotechnology.
