Management of Russian wheat aphid, Diuraphis noxia (Homoptera: Aphididae) using Seed treatment insecticides and its effect on yield and yield components of wheat


Tadele Shiberu

Russian wheat aphids (Diuraphis noxia) is a major constraint of insect pests of wheat crops in Ethiopia. In an attempt to understand the effect of seed dressing of chemical insecticides against Russian wheat aphids (D. noxia). The experiment was carried out at Ambo from June to November 2018, and 2019. The experiments were laid out in randomized complete block design within three replications. The result indicated that the seed dressing insecticide (Seed star 24% FS) and Titan 25 WDG resulted interesting during the study year. Significant (P < 0.05) differences were observed from untreated control. The treatments showed persistent effects and gave significant control over untreated check-ups to harvesting. At flowering and maturity stages, the treated treatments were infested 0-3.78 in 2018 and 0.4.13 in 2019 while the infestation of untreated control increased to 34.55 aphids/ plant in 2018 and 42.25 in 2019. At the maturity stage, the population of aphids in treated treatments increased from 2.25-23.35 aphids/plant and 8.13-33.12 aphids/plant, in 2018 and 2019, respectively. But at the maturity stage, the population of aphids per plant was observed 39.35 in 2018 and 43.25 aphids per plant were observed. These results showed that when the crops attain near ripeness, the infestation level of aphids increases. The use of seed dressing chemical insecticides was the safest, cheapest, and mainly successful means of controlling Russian wheat aphids at early stages.
