The rise in global temperature also favors the multiplication of pests and pathogens, which calls into question food security. Plants have developed special coping mechanisms since they are sessile lack an immune system. These use a variety secondary metabolites as weapons to avoid obstacles, adapt their changing environment, survive less-than-ideal circumstances. Plant include phenolic compounds, alkaloids, glycosides, terpenoids, stored specialized structures such latex, trichomes, resin ducts, etc. Secondary help plants be safe from biotic stressors, either by repelling them or attracting enemies, exerting toxic effects on them. Modern omics technologies enable elucidation structural functional properties these along with biosynthesis. A better understanding enzymatic regulations molecular aids exploitation modern pest management approaches biopesticides integrated management. current review provides overview major plant that play significant roles enhancing stress tolerance. It examines involvement both indirect direct defense mechanisms, well storage within tissues.

Bioactive limonoids from Carapa guianensis seeds oil and the sustainable use of its by-products

Current Research in Toxicology, Journal Year: 2023, Volume and Issue: 4, P. 100104 - 100104

Published: Jan. 1, 2023

Carapa guianensis (Andiroba, Meliaceae) is considered a multipurpose tree. In Brazil, Indigenous people have used it as insect repellent and in the treatment of various diseases. Most biological activities popular uses are attributed to limonoids, which highly oxygenated tetranortriterpenoids. More than 300 limonoids been described Meliaceae family. Limonoids from Andiroba oil shown high anti-inflammatory anti-allergic vivo, by inhibiting platelet activating factors many inflammatory mediators such IL-5, IL-1β TNF-α. It also reduced T lymphocytes, eosinophils mast cells. corroboration with wide use oil, no significant cytotoxicity or genotoxicity vivo was reported. This promotes apoptosis gastric cancer cell line (ACP02) at concentrations, without showing mutagenic effects, suggested increase body's nonspecific resistance adaptive capacity stressors, exhibit some antioxidant activity, protect against oxidative DNA damages.

Published: March 17, 2023

Sustainability in food production is an increasingly discussed issue nowadays; therefore, demands for research that can reduce costs and ensure the quality autonomy of are relevant, with attention to use plants due their importance biodiversity. Thus, objective this was evaluate bioactivity, feeding preference, oviposition preference Miconia albicans botanical extracts at concentrations 1%, 5%, 10% against Plutella xylostella. We observed reduced larval duration, survival, female hatching success, repellence all concentrations. For higher concentrations, showed a mortality rate 58%, reduction 82%, 94%, showing potential pest control. Phytochemical analyses identified phenolic compounds, flavonoids, tannins, which substances repellent larvicidal properties. This first report on phytosanitary M. albicans, plant has both lethal sublethal effects P.

Aphid-Resistant Plant Secondary Metabolites: Types, Insecticidal Mechanisms, and Prospects for Utilization

Plants, Journal Year: 2024, Volume and Issue: 13(16), P. 2332 - 2332

Published: Aug. 21, 2024

Aphids pose a significant threat to global agricultural crop production, leading widespread pesticide use and resistance. This necessitates the of alternative substances, like plant secondary metabolites (PSMs). Plants have developed protective compounds known as alkaloids, terpenoids, phenolics, sulfur- nitrogen-containing metabolites. These exhibit promising characteristics against aphids, such antifeedant, aphicidal, disrupting survival fitness. review highlights importance application in combating aphid populations. Different insect-resistant substances different mechanisms for managing aphids other pests, including defensive signaling, inhibiting growth, attracting natural predators by releasing herbivore-induced volatiles (HIPV). The biopesticides has proven be an effective, economical, eco-friendly synthetic chemicals. Furthermore, this comprehensively discusses principle role metabolites, encouraging sustainable practices emphasizing integrated management population.

Plant-originated triterpenes are important insecticidal molecules. Research on the activity of molecules from Meliaceae plants has always been a hotspot due to this family showing variety activities with diverse mechanisms action. In paper, we discussed 116 triterpenoid 22 plant species five genera (Cipadessa, Entandrophragma, Guarea, Khaya, and Melia) in Meliaceae. these genera, Entandrophragma Melia have attracted substantial research attention recent years. Specifically, systemically studied for several decades. total, chemicals consisted 34 ring-intact limonoids, 31 ring-seco 48 rearranged 3 tetracyclic triterpenes. Furthermore, limonoids included 29 trichilin-class chemicals, azadirone-class 1 cedrelone-class havanensin-class limonoid.
