Yang ML, Zhang JZ, Zhu KY, Xuan T, Liu XJ, Guo YP, Ma EB: Mechanisms of organophosphate resistance in a field population of oriental migratory locust, Locusta migratoria manilensis (Meyen). Arch Insect Biochem Physiol. 2009 May;71(1):3-15.
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). |

Zhang YL, Mu W, Chen ZL, Han ZR, Ma C, Zhai RH: [Susceptibility and related physiological and biochemical mechanisms of Carposina niponensis Walsingham larvae on six insecticides before and after overwintering]. Ying Yong Sheng Tai Xue Bao. 2007 Aug;18(8):1913-6.
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. |
