Determination of enzyme activities of susceptible and field populations of <em>Helicoverpa armigera </em>(Hubner) (Lepidoptera: Noctuidae) and its relationship with insecticide resistance
Abstract
The purpose of this study was to determine the activities of general esterase, glutathione S-transferase (GST), and acetylcholinesterase (AChE) enzymes of Helicoverpa armigera (Hubner) strains, one of the most important pests of cotton, collected from cotton fields in Adana, Hatay, Antalya and susceptible strain (Israel), and to determine their relationship with insecticide resistance. The activities of general esterase, glutathione S-transferase enzyme (GST) and acetylcholinesterase (AChE) enzymes were determined in Helicoverpa armigera strains. The activities of general esterase enzyme in Adana, Hatay and Antalya populations were determined 0.65, 0.8 ve 1.14 fold, respectively. Adana and Hatay strains had lower general esterase enzyme activities than that of susceptible strain. However, general esterase enzyme activity in Antalya strain was found to be similar to susceptible strain. GST enzyme activities in Adana, Hatay and Antalya populations were determined 0.75, 0.92 ve 1.06 fold, and AChE enzyme activities were 0.43, 0.60 and 0.80 fold, respectively. GST and AChE enzyme activities of field strains and susceptible strain were found to be similar. Enzymes activities and insecticide resistance had been compared with the resistance ratios of at the same populations, to determine the relationship between enzyme activities and insecticide resistance in H. armigera.
