This study investigates the effects of varying populations of two-spotted spider mites (Tetranychus urticae Koch)
on the growth parameters and yield of summer apple cultivars. Field experiments were conducted to measure the impact
of mite infestations at different density levels on leaf chlorophyll content, fruit growth, leaf area, and overall yield. Results
demonstrated significant negative correlations between mite populations and apple growth metrics. High mite densities
severely decreased leaf chlorophyll content, leaf area, and fruit size, subsequently reducing overall yield. Effective mite
management strategies are necessary to maintain optimal apple production levels.
