Abstract

Aphid is assumed one of the most severe pests attacking wheat causing harm to the plants either directly by sucking juice or indirectly as a vector of diseases. Host plant resistance is a sturdy component in Integrated Pest Management (IPM) to decrease the injury of aphid insects. We studied the population abundance and susceptibility of two Egyptian wheat cultivars (Misr 1 and Misr 3) to Aphidspp < /span> infestation. The results indicated that the total number of Aphidson wheat Misr 1 variety during the seasons, 2019-2020 and 2020- 2021 were 536 and 191 respectively whereas, on Misr 3 variety were 1274 and 1388 respectively. The results of the simple-correlation during 2020 season, aphid density was insignificantly correlated with a daily mean of maximum temperature, daily mean of minimum temperature, daily mean of rainfall and R.H%, whereas, the relationship was significant with predatory insects. In 2021, a significant relationship < /span> with a daily mean of maximum temperature, daily mean of minimum temperature and predatory insects were found. For the effect of plant age, simple correlation showed a positive and significant effect with Age1 and Age2 with (r) values were 0.58 and 0.48 respectively,whereas the second season was negative and insignificant with Age2 and Age3 and positive insignificant effectwith Age1. Here, we tested the susceptibility of two wheat varieties to the infested with Aphid density, the highest infestation of aphid species on wheat Misr 3 variety associated with highest total protein (12.2%) and total phenols content (0.95±0.04 mg/gm), whereas, the least infestation byaphid specieson wheat Misr 1 variety associated with least total protein and phenols content.
