<p>Wheat, the major crop in Pakistan, suffers significant losses due to aphids, mainly <i>Rhopalosiphum padi</i>,<i> which</i> suck the plant’s cell sap and transfer fungal and viral illnesses indirectly. Rainfall, relative humidity and temperature greatly influenced the aphid population. The main objective of the current study was to assess the impact of weather factors on the population dynamics of aphids. A field study was conducted to check the occurrence and abundance of aphids on the wheat crop in the district of Faisalabad during the years 2021–2022. The experiment was carried out in a Randomized Complete Block Design with three replications. Weekly data were analyzed on Statistix (v8.1), and means of aphid population on different wheat varieties were compared by Tukey’s post hoc multiple comparison test at <i>P</i> = 0.05. Among ten varieties of wheat, Faisalabad-08 had a markedly higher seasonal mean aphid population than other cultivars; Punjnad-01 had the lowest population of aphids. Aphid populations were statistically greater in March 2022 than in February or April 2022. The effect of abiotic parameters such as relative humidity (%), rainfall (mm) and temperature (^oC) on the population fluctuation of aphids was recorded. According to correlation analysis of the aphid population with weather parameters, the temperature had a favourable and significant impact on the aphid population (<i>r</i> = 0.7402, <i>P</i> &lt; 0.01). Rainfall also has a detrimental but insignificant influence on the aphid population (<i>r</i> = -0.2623), while relative humidity has a significantly negative impact on the aphid population (<i>r</i> = -0.7587, <i>P</i> &lt; 0.01). The dynamics of the aphid population varied significantly across the ten genotypes of wheat. Current findings suggest that farmers should adopt Punjab-2011 and Punjnad-2001 due to their resistance against aphids in the region of Faisalabad.</p>
