“…We concluded that the host plant affects the development of pest and that the choice of the most resistance cultivar can help to reduce pest infestation, and are therefore an additional component to be included in the integrated pest management of wheat plants. Variations [29,1,18,19,17,23] .…”

Field experiments were conducted at wheat program of El-Mattana Agricultural Research Station, Luxor Governorate, Egypt during two successive growing seasons (2017/2018 and 2018/2019) to study the performance of some wheat cultivars and lines to infestation by Schizaphis graminum (Rondani) (Hemiptera: Aphididae) and their spatial distribution pattern. Results indicated that the total population density of S. graminum during the first growing season (2017/2018) was higher than second growing season (2018/2019). Also, the total mean of S. graminum population through the whole season was 20.83 ± 0.54 and 13.57 ± 0.34 individuals per 10 tillers over the first and second growing seasons, respectively. The obtained results indicated that Giza 171 and Giza 12 cultivars and lines of wheat (6, 11 and 13) were the highly susceptible varieties (HS) during the two seasons. On the other hand, Shandwel 1 and Sides 14 cultivars and lines 4 and 12 were rated as resistance to infestation (R) during the two seasons, these cultivars and lines of wheat plants should be promoted in the areas of high aphid infestation. It was also, noticed that the mean maximum population density of S. graminum was observed on Giza 171 cultivar, while, the minimum individuals of population were recorded on line 4 of wheat plants through the two growing seasons. Data were analysed using 21 distribution indices. All distribution indices indicated a significant aggregation behaviour during each growing season in all the tested wheat cultivars and lines. These pieces of information can be useful for planning an IPM program of aphid on wheat plants.
