Combined effect of seaweed (Sargassum wightii) and Bacillus thuringiensis var. israelensis on the coastal mosquito, Anopheles sundaicus, in Tamil Nadu, India

Efficacy of aqueous and alcoholic formulations extracted from Padina boryana algae against Aedes aegypti mosquito larvae: A comparative study

“…In a study conducted by Kumar et al, it was found that the application of Sargassum wightii crude extract resulted in higher mortality rates for both larvae and pupae. This increased mortality was attributed to the presence of bioactive compounds present in the seaweed, which were believed to have multiple mechanisms of action contributing to the observed effects on the mosquito life stages (Kumar et al 2012).…”

“…Therefore, there is a growing interest by researchers in exploring safe control methods that use natural materials and extracts that are environmentally friendly and do not contribute to the development of mosquito resistance. Several authors (for example, Al Yahya et al 2023;Alavez-Rosas et al 2022;Aljameeli 2023;Al-Mekhlafi et al 2013;Al-Rashidi et al 2022;Alyaha et al 2018;Alyahya 2023a;Alyahya et al 2021;Al-Zahrani et al 2019;Ansari et al 2000;Bantoto & Dy 2013;Barazandeh 2002;Bosly 2022;Choi et al 2002;Denner 2009;Fekadu et al 2009;Fernandez et al 2018;Hazarika et al 2018;Kumar et al 2012;Mahyoub 2018;Sutthanont et al 2022;Valentina et al 2015) have conducted experiments and tests on diverse terrestrial and marine plant extracts to assess their efficacy against the larvae of various mosquito species, including Aedes, Culex, and Anopheles mosquitoes. The results of these studies showed differences between researchers, but overall they presented promising results regarding the possibility of plant extracts as an alternative to chemical pesticides because these extracts contain biologically active compounds with insecticidal properties.…”

Bioactive properties of brown seaweed, Sargassum wightii and its nutritional, therapeutic potential and health benefits: A review

“…Industrial applications of S. wightii: Organic farming is production of organic food items without using conventional pesticides and synthetic fertilizers. Due to the presence of potassium chloride in seaweed, they are used as bio-fertilizers or manure in many countries for cultivating crops and for plants that require growth promoters, including potash, sulphate, trace elements and radicals (Kumar et al, 2012;Muthezhilan et al, 2014;Baliah et al, 2017;Uthirapandi et al, 2018). Liquid fertilizer extracted from S. wightii when used as foliar spray has been found to induce faster growth and yield in vegetables, fruits, orchards and horticulture plants (Sivasankari et al, 2006;Jothinayagi and Anbazhagan, 2009;Divya et al, 2015).…”

“…S. wightii extracts can be used as biocides against plant and animal pathogens (Kumar et al, 2012;Asaraja and Sahayaraj, 2013;Suganya et al, 2019;Niroja and Kannan, 2020). S. wightii has a unique ability to act as a bio sorbent, since the cell wall structure shows biosorbent properties as it can bind with the ions, metals and toxic substances present in sewage and, therefore, can be used in the biosorption-based bioremediation techniques.…”
