Larvicidal efficacy of plant extracts and isolated compounds from Annonaceae and Piperaceae against Aedes aegypti and Aedes albopictus

Asian Pacific Journal of Tropical Medicine, 2020
The Aedes (Ae.) aegypti and Ae. albopictus mosquitoes are vectors of epidemiologically relevant arboviruses in the public health context, such as the dengue, Zika and chikungunya viruses.

Metabolomic Differentiation of Malpighiaceae From Dry and Humid Tropics via UHPLC‐MS/MS and Chemometrics

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Various factors can trigger water stress in plants, particularly in those growing in dry tropical regions. To survive under such conditions, plants produce metabolites with adaptive functions. However, metabolomic data on the leaves of Malpighiaceae species cultivated in both dry and humid tropical areas of Brazil remain scarce.

Bioassay-guided isolation and identification of Aedes aegypti larvicidal and biting deterrent compounds from Veratrum lobelianum

Open Chemistry, 2018
An ethanol extract from Veratrum lobelianum Bernh. rhizomes showed larvicidal activity with LC50 values of 11.79 ppm and 89.9 ppm against 1st and 4th instar larvae, respectively, at 24 h post-treatment. The extract also showed proportion not biting (PNB)

From fertilizer to insecticide: urban leaf litter chemistry alters the survival landscape of Aedes aegypti

Pest Management Science, Volume 82, Issue 4, Page 3395-3407, April 2026.
Chemical profiling and bioassays reveal that leaf‐litter leachates from urban trees flip between nourishing and killing Aedes aegypti larvae: dilute Tipuana tipu boosts growth, whereas concentrated, aged extracts are >90% lethal. Species‐specific chemistry thus turns street trees into potential self‐renewing tools for integrated vector control ...

Extract of Sapindus saponaria L., a Native Amazonian Plant, Impacts Germ Cell Development and Modulates Longevity

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT Sapindus saponaria L. (S. saponaria), popularly known as “saboeiro” or “monkey soap,” is traditionally used in South America for inflammatory, infectious, and dermatological conditions. Despite its wide use, toxicological data remain limited, and the presence of triterpenoid saponins raises safety concerns.

Histopathological effects of cypermethrin and Bacillus thuringiensis var. israelensis on midgut of Chironomus calligraphus larvae (Diptera: Chironomidae) [PDF]

, 2018
Pesticides are extensively used for the control of agricultural pests and disease vectors, but they also affect non-target organisms. Cypermethrin (CYP) is a synthetic pyrethroid used worldwide. Otherwise, bioinsecticides like Bacillus thuringiensis var.

Antidiabetic Potential of Ligands from NEIST_PMIB_06, Bacterium Associated With Hawaijar (Fermented Soy Food): Insight from in Vitro and in Silico Studies

ChemFoodChem, Volume 2, Issue 1, March 2026.
ABSTRACT In this study, a bacterium (NEIST_PMIB_06) was isolated from Hawaijar, a fermented soy food from Manipur, Northeast India. The bacterium was inoculated and incubated to isolate bioactive compounds. Liquid‐liquid extraction was performed to obtain extracts (cell‐free and cell‐based), and their efficacy was evaluated.
