[Objectives]  To clarify the role of temperature on detoxification enzymes and pesticide resistance in Apolygus lucorum. [Methods]  Temperature-dependent "bell shaped" curves of the three main detoxification enzymes of A. lucorum were measured, and the effects on these curves on different insecticides were determined. [Results]  The results show that the activity of the three main detoxification enzymes are highest at 25℃, and significantly higher within the range of 10-40℃ than at other temperatures. The impact of detoxification enzymes of A. lucorum on insecticides that have temperature-dependent effects, indicate that the GST may be involved in the chlorfenapyr detoxification mechanism, the effectiveness of which is reduced by temperature in this insect. Between 20-30℃ the GST may be involved in the partial detoxification of imidacloprid and phoxim, and the low toxicity of hexaflumuron at low temperatures may also be correlated with this enzyme. CarE and MFO activity increased at about 15℃, and could be induced by the insecticides chlorfenapyr and hexaflumuron. Between 20-35℃, the activities of these two enzymes were not easily induced by the tested insecticides, but they could be inhibited by phoxim, chlorfenapyr and imidacloprid to some degree. [Conclusion]  The results show that, after induction by pesticides, the activities of certain detoxification enzymes of A. lucorum are clearly affected by temperature, and that can have a significant influence on pesticide performance.
