Abstract: The experiment conducted for the evaluation of mulberry varieties for yellow mite, Polyphagotarsonemus latus (Banks) infestation and basis of their reaction on 100 germplasm entries (including breeding lines and cultivated varieties) available in the experimental block of Department of Sericulture at GKVK, Bengaluru at quarterly interval from October 2019 to January 2021 (6 intervals viz., October 2019, January 2020, April 2020, July 2020, October 2020 and January 2021). Yellow mites remained abundant almost equally on all entries and most of the entries (97 entries) harboured a greater number of mites (> 50 mites/ cm2 leaf area), while only three entries (AR - 12, KPG - 1 and ME 018) recorded relatively a smaller number of mites (<50 mites).
