What is Chlorfenapyr?
Description
Chlorfenapyr is a pyrrole pro-insecticide that is metabolized in vivo into CL 303268 by mixed function oxidases. Chlorfenapyr increases respiratory activity in German cockroaches when used at concentrations ranging from 1 to 10 μg per insect but has no effect on respiration in Sf9 cells when used at concentrations ranging from 1 to 100 μM and does not affect respiration in isolated rat liver mitochondria up to a concentration of 10 μM. Chlorfenapyr is active against a variety of insects including those susceptible and resistant to pyrethroid and organophosphate insecticides, including horn flies (H. irritans) as well as A. culicifacies and A. stephensi mosquitos that carry malaria (LC50s = 2-2.39% suspension impregnated on paper). Chlorfenapyr is lethal to rats with LD50 values of 441 and 1,152 mg/kg for male and female rats, respectively. Formulations containing chlorfenapyr have been used to control termites and in agriculture to control various insects.

The Uses of Chlorfenapyr
Chlorfenapyr is a halogenated pyrrole based pro-insecticide. Chlorfenapyr functions by metabolizing into an active insecticide after entering the host. Chlorfenapyr is used primarily as a means of pes t control on cotton.
The Uses of Chlorfenapyr
Insecticide. Acaricide.
Definition
ChEBI: Chlorfenapyr is a member of the class of pyrroles that is 4-bromo-1H-pyrrole-3-carbonitrile which is substituted at positions 1, 2 and 5 by ethoxymethyl, p-chlorophenyl and trifluoromethyl groups, respectively. A proinsecticide used for termite control and crop protection against several insects and mite pests. It has a role as a proinsecticide and a proacaricide. It is an organofluorine acaricide, an organochlorine acaricide, an organochlorine insecticide, an organofluorine insecticide, a member of monochlorobenzenes, a nitrile, a member of pyrroles and a hemiaminal ether. It is functionally related to a tralopyril.
Hazard
A poison by ingestion. Moderately toxic by inhalation.
