The susceptibilities to three organophosphate (OP) insecticides (malathion, chlorpyrifos, and phoxim), responses to three metabolic synergists [triphenyl phosphate (TPP), piperonyl butoxide (PBO), and diethyl maleate (DEM)], activities of major detoxification enzymes [general esterases (ESTs), glutathione S-transferases (GSTs), and cytochrome P450 monooxygenases (P450s)], and sensitivity of the target enzyme acetylcholinesterase (AChE) were compared between a laboratory-susceptible strain (LS) and a field-resistant population (FR) of the oriental migratory locust, Locusta migratoria manilensis (Meyen).

To explain this difference the following hypotheses were tested: (1) phoxim is a promoter of isofenphos-induced OPIDP; (2) whereas neuropathy target esterase (NTE) is thought to be the target of OPIDP, activation of isofenphos by liver microsomes causes the formation of more potent NTE inhibitor (s) in humans than in hens; (3) in contrast to hen NTE, the sensitivity of the human enzyme to such inhibitor (s) is higher than that of acetylcholinesterase (AChE), the target of cholinergic toxicity.

The study with impregnating method showed that after overwintering, the susceptibility of Carposina niponensis larvae on triazophos, phoxim, chlorpyrifos, malathion, lambda-cyhalothrin and abamectin was 34.50, 16.71, 3.89, 3.28, 5.90 and 2.73 times as much as that before overwintering, the total protein, glycogen and fat contents and carboxylesterase, acid phosphatase, alkaline phosphatase, glutathione-S-transferase, superoxide dismutase, catalase and peroxidase activities in C. niponensis larvae were decreased by 17.10%, 41.76% and 30.08%, 62.36%, 53.47%, 76.19%, 80.60%, 18.77%, 14.16% and 64.02%, respectively, and the activity of acetylcholinesterase, the target enzyme of many insecticides, was 1.41 times as much as that before overwintering.

Five organophosphorous pesticides, monocrotophos, omethoate, parathion-methyl, phoxim and dichlorvos, were examined for their effects on mammalian cell lines to determine their potential impact on physiological functions in vivo.
The different pesticides reduced the acetylcholinesterase (AChE) activity of the rat neuronal cell line PC12 in a dose-dependent manner up to 100 microM.

It was based on the inhibitory effect of the pesticides on acetylcholinesterase (AChE), and the use of 5,5'-dithiobis (2-nitrobenzoic) acid (DTNB) as a chromogenic reagent for the thiocholine iodide (TChI) released from the acetylthiocholine iodide (ATChI) substrate.
