Abstract
Russian wheat aphids (Diuraphis noxia) are one of the most important pests on wheat in the world. This study was conducted to determine the effect of selected herbicides on the Russian wheat aphids. D. noxia were reared on wheat and all herbicide experiments conducted under controlled laboratory conditions. Assessments were made before the application of herbicides, and at 3, 7, 14 and 21 days after application (DAA). The lowest densities of D. noxia were seen on 2,4-D ester-treated plants. The smallest leaf chlorosis caused by D. noxia was found on tribenuron-methyl-treated plants at 3 DAA, and tribenuron-methyl-treated plants had the lowest leafrolling damage caused by D. noxia. Although all untreated plants were easily broken at the soil surface at 21 DAA, it was observed that all herbicide-treated plants were bent downward slightly but not broken. The active ingredients of fenoxaprop-p-ethyl fenohlorazole-ethyl, tribenuron-methyl and 2,4-D ester had a negative impact on D. noxia, and suppressed aphid populations from 3 DAA. Statistical analyses showed that effects of all herbicides used in the experiment were significant.
