Food scientists from the National University of Singapore (NUS) developed a rapid and highly sensitive screening technique capable of detecting minute amounts of pyrethroids in vegetables, a common type of synthetic pesticide applied on agricultural crops.
Following this move, the only termiticides offered for use as soil barrier treatments were either chlorpyrifos (belonging to the organophosphate class) or several pyrethroids.
Only pyrethroids are used for LLINs because they are safe, efficacious against malaria vectors, and relatively low cost (5-7).
The present research work was conducted to evaluate the repellent and growth inhibitory efficiency of five plant extracts (Azadirachta indica, Melia azadirach, Pegnum hermala, baryosma and Zingiber officinale) and three synthetic pyrethroids (bifenthrin, cypermethrin and deltamethrin) on three geographical populations of Callosobruchus chinensis collected during 2013 from Faisalabad, Multan and Nankana districts of Punjab, Pakistan.
Runoff of pyrethroids, widely used household insecticides, has led to contamination of urban waterways as well as a need to accurately assess pyrethroid concentrations in waterways.
However, in recent years moe than three dozen countries have reprted confirmed resistance of Anopheles mosquioes to pyrethroids, (9) the only cass of insecticide currently used on bed nets (whch are a key element of malaria prevention)and, until recently, the primary class usd in indoor residual sprays.
Maybe, IRS has some utility in areas with low resistance as part of an overall resistance management strategy aimed at preserving the effectiveness of pyrethroids (16).
Pyrethroids are synthetic chemical insecticides that act like pyrethrins.
This initiative has led to the use of environmentally friendly insecticides that can undergo biodegradation and have minimal impact on the environment such as pyrethrums and pyrethroids.
Pyrethroids constitute a family of insecticides widely used in a variety of sectors: agriculture (various crops), veterinary (antiparasitics) and domestic (lice shampoo, mosquito products).
Specific classes of pesticides studied were organophosphates, pyrethroids and carbamates.
