Population Dynamics of Sitobion avenae (Hemiptera: Aphididae) and their Mummified Aphids on Wheat Crop

Wheat (Triticum aestivum L.) is one of the major nutritional bases mankind and animals worldwide; however, infestations by aphids are main cause that severely affects wheat production in Pakistan around world. In 2021-22 population densities Sitobion avenae their mummified were studied on crop under field conditions at University Research Farm, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi. About eight quadrats taken each day from whole weekly basis numbers counted visually plant part (stems, leaves, spikes) individually. Seasonal mean aphid morphs revealed found significantly different among winged, adults, nymphs, mummies (F5, 551 = 8.38, P 0.000; F5, 14.80, 24.13, 18.30, 0.000 respectively). Significantly greater recorded spikes (29.23 ± 1.14) as compared to those leaves (8.46 0.68) stems (0.37 0.05). The overall combined comparison was observed non-significant between adult, nymph, (F7, 0.20, 0.984; F7, 0.07, 0.999; 0.08, 0.50, 0.829 respectively) crop. Therefore, S. peak timing reported this study will be helpful a critical infestation period for scheduling management practices
