Abstract
A method for checking for sensitivity of acetylcholine esterase in insects using a single insect, includes homogenizing a single insect in aqueous, neutral to acid pH phosphate buffer, providing a solution of acetylcholine iodide in neutral to acid pH phosphate buffered water-miscible organic solvent, providing a solution of 5,5-dithio-bis-(2-nitrobenzoic acid) in the buffer, and providing a solution of propoxur in the buffer, dropping the insect homogenisate into the wells of an assay plate, dropping the acetylcholine iodide and 5,5-dithio-bis-(2-nitrobenzoic acid) solutions into some of the wells and 5,5-dithio-bis-(2-nitrobenzoic acid) propoxur solutions into the other wells and checking for a difference in the yellow coloration between the samples in the two sets of cells.
