- Opis:
- It is necessary to study the biochemical changes in insects exposed to toxicants if we want to predict the potential of various chemicals on the natural enemy. Physiological energy, as a biochemical biomarker, may be affected by many pesticides including organophosphate compounds. Therefore, in this study, the sublethal effects of diazinon, fenitrothion, and chlorpyrifos on the cellular energy allocation (CEA) of the predatory bug, Andrallus spinidens Fabricius (Hemiptera: Pentatomidae), a potential biological control agent, was studied on 5th-instar nymphs. Among the energy reserves of the A. spinidens nymphs, only total protein was significantly affected by pesticide treatments, and the highest value was observed in chlorpyrifos treatment. The energy available (Ea) and energy consumption (Ec) in A. spinidens were significantly affected by these pesticides. In exposed bugs, these parameters were affected by fenitrothion and chlorpyrifos more than diazinon. The activity of the electron transport system (ETS) in the Ec assay showed that A. spinidens exposed to chlorpyrifos had the highest rate of oxygen consumption. Although, there was no significant change in CEA, the insecticides caused a marked change in the physiological balance of A. spinidens. The results suggested that the adverse effect of these insecticides on A. spinidens should be considered in Integrated Pest Management (IPM) programs.
