Larvicidal activity of para-Benzoquinones

Parasitology Research, 2010
Plant products may be alternative sources of mosquito larval control agents, since they constitute a rich source of bioactive compounds that are biodegradable into nontoxic products. It has been reported that quinones and derivatives present toxic activity against mosquito larvae Aedes aegypti.

Larvicidal activity of chimeric Bacillus thuringiensis protoxins

Molecular Microbiology, 1990
Summary Bacillus thuringiensis subspecies kurstaki (Btk) and subspecies berliner (Btb) both produce lepidopteran‐specific larvicidal protoxins with different activities against the same insect species. Toxic activity resides in the amino‐terminal half of both protoxins, whereas the carboxy‐terminal half of the molecules is not required for toxicity ...

Metal tolerance and larvicidal activity of Lysinibacillus sphaericus

World Journal of Microbiology and Biotechnology, 2013
Lysinibacillus sphaericus is a spore-forming bacterium used in the biological control of mosquitoes and in bioremediation. Mosquito larvae exposed to heavy metals are tolerant to concentrations above the permissible limit for industrial residual waters. In this work, we characterize 51 L.

Toxocara canis: Larvicidal activity of fatty acid amides

Bioorganic & Medicinal Chemistry Letters, 2016
Considering the therapeutic potential of fatty acid amides, the present study aimed to evaluate their in vitro activity against Toxocara canis larvae and their cytotoxicity for the first time. Linoleylpyrrolidilamide was the most potent, with a minimal larvicidal concentration (MLC) of 0.05 mg/mL and 27% cytotoxicity against murine peritoneal ...

1-Phenylisoquinoline larvicidal activity againstCulex quinquefasciatus

Natural Product Research, 2012
The larvicidal potential of several dopamine 1-phenylisoquinoline derivatives against Culex quinquefasciatus third instar larvae was investigated in a rational search for insecticides. The results showed that these isoquinolines presented moderate larvicidal activity, that the presence of a substituent is needed on carbon 1 for such activity to be ...

Structure–activity relationship (SAR) modelling of mosquito larvicides

SAR and QSAR in Environmental Research, 2015
An attempt was made to derive structure-activity models allowing the prediction of the larvicidal activity of structurally diverse chemicals against mosquitoes. A database of 188 chemicals with their activity on Aedes aegypti larvae was constituted from analysis of original publications.

Ovo-Larvicidal Activity of Selected Insecticides, 1988

Insecticide and Acaricide Tests, 1989
Abstract A field evaluation was conducted at the Red River Research Station, Bossier City, La., to determine ovicidal activity and residual toxicity of selected insecticides and insecticide combinations against tobacco budworm on cotton. Plots were 4 rows by 30.5 m arranged in a randomized complete block with 4 replicates.
