Integrated Experimental, Chemometric, and In Silico Analyses of Larvicidal Supercritical Extracts From Myrtaceae Species Against Aedes aegypti

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
The cross‐validated regression tree showed modest predictive performance. Mortality was not significantly associated with the first two PCA axes. Molecular modeling generated testable ligand–target hypotheses. Psidium cattleianum had lower LD50. The larvicidal activity of the crude extracts could not be attributed to individual constituents.

Effects of Kathon, a Chemical Used Widely as a Microbicide, on the Survival of Two Species of Mosquitoes

Molecules, 2021
In recent decades, demands for novel insecticides against mosquitoes are soaring, yet candidate chemicals with desirable properties are limited. Kathon is a broad-spectrum isothiazolinone microbicide, but other applications remain uncharacterized. First,

From Past Outbreaks to Future Threats: Detecting Medical Conspiracy Theories With LLMs and Limited Labels

Expert Systems, Volume 43, Issue 9, September 2026.
ABSTRACT Online dissemination of conspiracy theories (CTs) during epidemics poses significant risks to public health. This paper addresses the problem of detecting CTs in social media posts with an emphasis on the resource‐constrained scenarios characterized by the scarcity of labelled datasets and expert annotations, and the lack of computational ...

Botanicals as Mosquito Larvicides

Defence Science Journal, 2006
Methanol extracts of 19 indigenous plants were evaluated as mosquito larvicide. Among these, pericarp of Zanthoxylum limonella was found to have the most promising larvicidal properties against Aedes(s) albopictus and Culex quinquefasciatus with LC 90 values at 0.47 ppm and 0.73 ppm, respectively.

The effects of Bacillus thuringiensis var. israelensis (Bti) on tropical stream food webs vary between two consecutive dry seasons

Insect Conservation and Diversity, Volume 19, Issue 5, Page 1288-1296, September 2026.
Bti application altered tropical stream food‐web structure through changes in macroinvertebrate functional feeding groups. Collector‐filterers and predators showed context‐dependent responses, with clearer direct and indirect effects detected in 2016, the year with higher rainfall.
