- Abstract
An experiment was conducted to study the population density of cereal aphids and their natural predators under the effect of different wheat varieties. Ten local wheat varieties were laid in the RCBD design having four replications, each having 2 sub-plots at the New Developmental Farm, Khyber Pakhtunkhwa Agricultural University, Peshawar (NDF, KP-AUP). Data for the aphid population pattern, their predators, aphid parasitoids, and ultimate losses to grain yield and biomass were recorded. Moreover, population distribution pattern on different plant parts was also studied. Result indicated that Saleem-2000 appeared to be the resistant cultivar having minimum aphid infestation (4.65) before booting stage, due to maximum beetle population (0.15). However, after the booting stage, Pirsabak-2004 received the maximum aphid infestation (2.90) due to minimum beetle population plant-1 (0.08). Moreover, R.padi and S.avenaee are the dominant species of aphids during vegetative and reproductive crop stages, respectively. Higher grain yield losses (31.12%) under aphid infestation over the control were recorded in Ghaznavi- 98 while Fakhr-e-sarhad (0.74%) showed minimal yield losses.
