Total counts of wheat aphids (a) and natural enemies (b). The counts are based on data collection during 2019 from a wheat-trial, involving different stressed and unstressed stages of wheat crop as stress treatments. The field used for data collection was located at the University Farm in Multan, Pakistan. Bars topped with the same letter are not significantly different (P˃0.05; LSD test). *Total densities are the means of three replicates.
