[0065] 1. Efficacy of transfluthrin against Aedes aegypti

[0066] Solvent: Acetone

[0067] To produce a suitable preparation, transfluthrin was dissolved in acetone. The solution of the active ingredient was drawn onto the glazed tiles, and after drying, the Aedes aegypti species ( Target resistant strain: Grand Cayman ) adult mosquitoes were placed on the treated bricks. The exposure time was 30 minutes.

[0068] After 0.25 hours, 0.5 hours, 1 hour, 2 hours, 3 hours, 4 hours, 24 hours of contact with the treated surface, the knockdown ratio of the test animals was determined in %. Here, 100% (efficacy) means that all mosquitoes are killed; 0% (efficacy) means that none of the mosquitoes are killed.

Abstract

The invention is in the technical field of insect control and relates to the use of a compound comprising a polyfluorobenzyl moiety for controlling insecticide-resistant pests such as mosquitoes and bed bugs.

Description

technical field [0001] The present invention belongs to the technical field of insect control and relates to the use of compounds comprising polyfluorobenzyl moieties for controlling insecticide-resistant pests such as mosquitoes and bedbugs. Background technique [0002] Currently, insecticides used for vector control (including mosquitoes and bedbugs) involve four chemical classes: pyrethroids, organochlorines (including DDT), organophosphates, and carbamates. Pyrethroids are used far more than the other three classes due to their rapid and long-lasting effects and their low toxicity and low cost. However, resistance to pyrethroids has recently been reported, which has become a major concern of the World Health Organization (WHO), and solutions on how to deal with emerging resistance are seen as critical for future vector control management. Very important (see eg http: / / www.who.int / malaria / world_malaria_report_2011 / chapter4.pdf). [0003] Two major mechanisms of insecti...
