Biopesticides in Sustainable Agriculture: Current Status and Future Prospects

Опубликована: Янв. 1, 2022

Intensive application of synthetic pesticides was the routine practice commercial agriculture during Green Revolution to boost agricultural productivity meet global food demand. Alongside this, chemical caused adverse effects on environment and its ecoreceptors including human health. Negative externalities arising from conventional farming instigated call for sustainable development sixties promote balance nexus between socially acceptable economic growth environmental protection. Consequently, a blueprint 17 Sustainable Development Goals (SDGs) 169 targets ecological stewardship security drafted. Eight out SDGs are directly linked based direct impact agriculture, judicious use critical resources conservation Principles green chemistry. As agent, biopesticides have been shown potentials substitute with equal productivity. The adoption bio-based via integrated pest management (IPM) has proven be most effective option influence dimensions agriculture. Therefore, biopesticide-driven IPM if utilized requisite education, skills research would This chapter reviews prospects, importance, limitations how is connected development, Chemistry, management.

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) on the “Offensive” in Africa: Prospects for Integrated Management Initiatives

Insects, Год журнала: 2020, Номер 11(11), С. 764 - 764

Опубликована: Ноя. 6, 2020

The South American tomato pinworm Tuta absoluta (Meyrick) has aggressively invaded the African continent. Since its first detection in North Africa Morocco and Tunisia 2008, it successfully entire southern, eastern western Africa, where been on offensive, causing significant damage to Solanaceous food crops. While control of this prolific invader is primarily based conventional synthetic pesticides, form consistently losing societal approval owing (1) pesticide resistance development consequential loss field efficacy; (2) growing public health concerns; (3) environmental contamination biological diversity associated ecological services; (4) unsustainable costs, particularly for resource-poor farmers. As such, more ecologically sound pest management strategies, e.g., use natural substances (NSs), may offer a sustainable approach tackling offensive. A systematic literature search through digital libraries online databases (JSTOR, PubMed, Web Science, SCOPUS Google Scholar) was conducted using predetermined keywords T. absoluta, pinworm. We explain invasion citing mechanisms facilitating exploring potential diverse agents, low-risk substances. Specifically, we explore how botanicals, entomopathogens, semiochemicals, predators, parasitoids, host plant resistance, sterile insect technique others have spatially employed discuss these agents landscapes integrated approaches. NSs as assets general control, some liabilities barriers adoption systems from legislative, economic, social standpoint.

Biological invasion risk assessment of Tuta absoluta: mechanistic versus correlative methods

Biological Invasions, Год журнала: 2021, Номер 23(12), С. 3809 - 3829

Опубликована: Авг. 10, 2021

Abstract The capacity to assess invasion risk from potential crop pests before of new regions globally would be invaluable, but this requires the ability predict accurately their geographic range and relative abundance in novel areas. This may unachievable using de facto standard correlative methods as shown for South American tomato pinworm Tuta absoluta , a serious insect pest native America. Its global invasive was not identified until after rapid Europe, followed by Africa parts Asia where it has become major food security problem on solanaceous crops. Early prospective assessment its is possible physiologically based demographic modeling that have knowledge gaps T. biology at low temperatures. Physiologically models (PBDMs) realistically capture weather-driven mechanistic way allowing evaluation areas climes including climate change. PBDMs explain biological bases distribution, are generally applicable species any taxa, limited terrestrial ecosystems, hence can extended support ecological aquatic ecosystems. address lack unified general assessing managing becoming more predictive science.

Phytochemical properties and insecticidal activity of hexane extract of Melia azedarach fruit against Tuta absoluta (Meyrick)

Archives of Phytopathology and Plant Protection, Год журнала: 2025, Номер unknown, С. 1 - 14

The tomato leaf miner (TLM), Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is important pest on tomato, potato and other Solanaceous with a huge economic importance. Management of the can be problematic, especially when infestation pressure high. Phytochemical contact toxicity hexane extract Melia azedarach L.

Green synthesis of zinc oxide nanoparticles from Sargassum ilicifolium to enhance tomato resistance against Tuta absoluta

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Апрель 19, 2025

This study evaluated the effects of ZnO and green-synthesized nanoparticles (ZnO-NPs) from Sargassum ilicifolium extract on biochemical interactions between tomato leaves destructive pest Tuta absoluta. The average size stability ZnO-NPs were characterized using DLS, X-RD, FE-SEM. Peaks in FT-IR spectrum algae ZnO-NPs, indicated presence carboxyl groups, amines, alkynes alcohols. Treated exhibited increased total chlorophyll anthocyanin contents, particularly at 100 50 ppm, compared to control. A significant increase flavonoid content was observed while phenolic also enhanced ppm. In T. absoluta larvae, exposure ppm led a reduction α-amylase, protease, protein, TAG levels, alongside catalase activity. Additionally, G6PD ALT activities decreased Lactate, MDA, RSSR/RSH Furthermore, elevated larval aldolase activity, AST γ-GT declined. These findings indicate that enhance defense mechanisms mitigate damage, supporting their potential use integrated management strategies against

Biological Control Potential and Drawbacks of Three Zoophytophagous Mirid Predators against Bemisia tabaci in the United States

Insects, Год журнала: 2020, Номер 11(10), С. 670 - 670

Опубликована: Окт. 1, 2020

Miridae (Hemiptera) of the tribe Dicyphini are important zoophytophagous predators use to control pest arthropods in vegetable crops. However, risk that their herbivory may cause economic damage could hinder application as useful biocontrol agents and limit likelihood they would meet regulatory requirements for importation. We conducted field cage studies assess predation capacity tomato plant three mirid species established south USA, a known agent (Nesidiocoris tenuis), two native (Macrolophus praeclarus Engytatus modestus). All significantly reduced number whiteflies (Bemisia tabaci) on plants compared without mirids. More damage, evaluated necrotic rings, was observed with E. modestus N. tenuis M. praeclarus. In our experiments included sesame (Sesamum indicum) plants, numbers increased despite low prey, thus showing benefit plant-feeding habit these predators. USA’s mirids therefore prove be immediately available biological management present future pests.

Bulletin of Entomological Research, Год журнала: 2021, Номер 111(4), С. 429 - 437

Опубликована: Фев. 15, 2021

Abstract The predatory mirid Macrolophus praeclarus is widely distributed throughout the Americas, and reported to prey upon several horticultural pest species. However, little known about its biology, thermal requirements, crop odour preferences, phytophagy, capability induce defensive responses in plants. When five temperatures studied (20, 25, 30, 33 35°C) were tested Ephestia kuehniella was used as prey, developmental time from egg adult on tomato, longest at 20°C (56.3 d) shortest 33°C (22.7 d). ability of nymphs develop adults decreased temperature increased, with highest number reaching stage (78.0%) lowest 35°C (0%). lower upper thresholds estimated 11.2° 35.3°C, respectively. maximum rate occurred 31.7°C constant 454.0 ± 8.1 degree days. predation E. kuehniell a eggs obtained 30°C. In Y-tube olfactory choice tests, M. selected sweet pepper eggplant odours more frequently than no plant control treatment. feeding did not damage tomato plants compared another zoophytophagous mirid, Nesidiocoris tenuis , which caused necrotic rings. phytophagy induced through upregulation jasmonic acid metabolic pathway. implications findings for using biological programmes Americas are discussed.
