Comparative sensitivity of larval mosquitoes to vegetable polyphenols versus conventional insecticides

Résumé

The larvicidal effects of polyphenols of natural crude decomposed alder leaf litter and commercially available tannic acid were experimentally compared with those of two common conventional insecticides (Bacillus thuringiensis ssp. israelensis: microbial insecticide; temephos: organophosphate insecticide). Comparative standard bioassays using third instar larval Aedes aegypti, A. albopictus, Culex pipiens and Coquillettidia richiardii as references indicated that Aedes and Culex taxa are far more sensitive to alder leaf litter than to tannic acid and conventional insecticides. C. richiardii is far more resistant to conventional insecticides than Aedes and Culex taxa, but its sensitivity to tannic acid is close to that of those taxa. Dietary vegetable polyphenols are thus proposed as new, practical, alternative chemicals for mosquito control when conventional insecticides are difficult and costly to be used (e.g., in the management of Aedes and Culex populations in man-made breeding sites and Coquillettidia control strategy).
