Abstract
Selective toxicity of dimethoate 40% E_C. at the rates of 0.4 and 0.8 L/ha, malathion 57% E.C. at the rate of 1.0 and 1.5 L/ha, pirimiphos-methyl 50% E.C (2.0 L/ha), and pirimicarb 50%W.P. (0.3 kg/ha) in controlling wheat aphids and their adverse effects on the coccinellid predators was carried out. The results showed that pirimiphos-methyl was the most toxic insecticide to wheat aphid, Schizoaphis graminum, while, malathion (1L/ha) was the least one. Pirimiphos-methyl treated plants produced significantly high levels of wheat grains followed by dimethoate (0.8 L/ha), pirimicarb (0.3 kg ma), dimethoate (0.4 L / ha), and malathion (1.0 and 1.5 L / ha) The data indicated that malathion (1.5L/ha) and dimethoate (0.8 L/ha) had significantly affected the food consumption of aphids by the laidy predator becthes, however, pirirniphos-methyl showed low effects in this respect. Malathion (I .5 L /ha) was the most nonselective insecticide to the three types of the beneficial coccinellid beetles where it caused 100 % mortality. However, pirimiphos-methyl was relatively more selective. Generally, it can be concluded that pirimiphos-methyl was efficient in controlling the wheat aphid but relatively safe for its natural enemies coccinellid predators under field conditions
