Pyrethroids (
phenothrin, etofenprox, and permethrin):These synthetic pyrethrins are more toxic than the natural forms, especially for fish and extending to cats.
Woudneh & Oros [21] found the compounds bifenthrin, cyfluthrin, cypermethrin, delta / tralomethrin, flucythrinate, [lambda]-cyhalothrin, permethrin and
phenothrin in five affluent sediments from the San Francisco Bay, USA.
In Merida, public health authorities replaced permethrin with
phenothrin for ULV space spraying in 2011 and then switched to the organophosphate chlorpyrifos in 2012.
The type segment is further classified in to bifenthrin, deltamethrin, permethrin, cypermethrin, cyfluthrin, lambda-cyhalothrin and other pyrethroids (fenvalerate, resmethrin, tetramethrin, allethrin,
phenothrin, barthrin, dimethrin, and bioresmethrin).
The forensic report confirmed that the water in the bottle contained a chemical substance called
phenothrin, which is used to manufacture insecticide.
Lab test results showed that a chemical substance named
phenothrin, which is used in manufacturing insecticides, had been mixed with the baby milk.
allethrin, bioallethrin, tetramethrin,
phenothrin, resmethrin, bioresmethrin, kadethrin, permethrin, cypermethrin, fenvalerate, deltamethrin and flumethrin.
"Type-I"-like pyrethroids include allethrin, bifenthrin, permethrin,
phenothrin, resmethrin, tefluthrin and tetramethrin.
Toxicity of delta-
phenothrin and resmethrin to non-target insects.
Insecticides - there are four main insecticides, three of which (malathion,
phenothrin and permethrin) are available from any community pharmacy.
Common non-residual ULV adulticides include an organophosphate (malathion) or pyrethroids (
phenothrin, allethrin, and resmethrin); all of which provide quick knockdown without residual effects (Dame & Fasulo 2002).
