17-epi-Melianodiol, a new protolimonoid from Melia azedarach fruits, exhibits larvicidal activity and is associated with oxidative imbalance and midgut epithelial damage in Aedes aegypti larvae. [PDF]
Pest Manag SciThe bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...

Synthesis and Larvicidal Activity of Novel Thenoylhydrazide Derivatives [PDF]
Scientific Reports, 2016 AbstractA pair of chemical isomeric structures of novel N-tert-butylphenyl thenoylhydrazide compounds I and II were designed and synthesized. Their structures were characterized by MS, IR, 1H NMR, elemental analysis and X-ray single crystal diffraction.

Antifungal and Larvicidal Activities of Phlorotannins from Brown Seaweeds [PDF]
Marine Drugs, 2021 Phlorotannins are secondary metabolites produced by brown seaweeds with antiviral, antibacterial, antifungal, and larvicidal activities. Phlorotannins’ structures are formed by dibenzodioxin, ether and phenyl, ether, or phenyl linkages. The polymerization of phlorotannins is used to classify and characterize.

A New Class of Glucosyl Thioureas: Synthesis and Larvicidal Activities [PDF]
Molecules, 2016 A novel series of glucosyl thioureas were synthesized in good overall yields (up to 37% over four steps) from d-glucose and primary amines, and their larvicidal activities toward Mythimna separata Walker were also investigated. This new class of glucosyl thioureas demonstrated low to moderate growth inhibition activity of Mythiman separata Walker, with

Larvicidal Activity of Grandisin Against Aedes aegypti
Journal of the American Mosquito Control Association, 2009 Dengue is a tropical disease caused by an arbovirus transmitted by the mosquito Aedes aegypti. Because no effective vaccine is available for the disease, the strategy for its prevention has focused on vector control by the use of natural insecticides. The aim of this study was to evaluate the larvicidal activity of the lignan grandisin, a leaf extract ...

Residual Larvicidal Activity of Quinones against Aedes aegypti [PDF]
Molecules, 2020 The number of documented dengue cases has increased dramatically in recent years due to transmission through the Aedes aegypti mosquito bite. Vector control remains the most effective measure to protect against this and other arboviral diseases including Zika, chikungunya and (urban) yellow fever, with an established vaccine only available for yellow ...

Membrane effects of dihydropyrimidine analogues with larvicidal activity
Colloids and Surfaces B: Biointerfaces, 2017 Two recently synthesized dihydropyrimidines (DHPMs) analogues have demonstrated larvicide and repellent activity against Anopheles arabiensis. DHPMs high lipophilicity suggests that these compounds may interact directly with the membrane and modify their biophysical properties.
