Sensitivity of acetylcholinesterases from Aphelenchus avenae to organophosphorous and carbamate pesticides

The sensitivities of acetylcholinesterases (ACHE) from the nematode Aphelenchus avenae and the house fly Musca domestica to various pesticides were compared using a colorimetric assay. ACHE from A. avenae were generally less sensitive than ACHE from M. domestica to inhibition by organophosphorous an...

Description
Summary:The sensitivities of acetylcholinesterases (ACHE) from the nematode Aphelenchus avenae and the house fly Musca domestica to various pesticides were compared using a colorimetric assay. ACHE from A. avenae were generally less sensitive than ACHE from M. domestica to inhibition by organophosphorous and carbamate pesticides. Carbamates were somewhat more inhibiting than organophosphorous pesticides to nematode ACHE. In vivo tests with concentrations of various pesticides up to 500 ppm in sand caused less than 100% mortality of nematodes.
