Fixed plot survey was carried out to know the extent of Jamun fruit damage caused by Meridarchis scyrodes at different locations. Observations were recorded at fortnight intervals from March to July, 2021 and 2022 Jamun fruiting season at five locations of Gokak taluk and one location of Hukkeri taluk in Belagavi district of Karnataka, India. Survey locations comprised in the study were KRCCH Arabhavi, Dupadal, Ankalagi, Kolavi, Kaitanal and Hidkal Dam with six available varieties (Dupadal, Kolavi local, Kaitanal local and Hidkal Dam local, Konkan Bahadoli and AJG-85). Pooled data depicted the peak incidence of M. scyrodes during II fortnight of June. Highest (58.25%) pest infestation was observed during I fortnight of July in Hidkal Dam local variety, at the same time less (12.50%) pest infestation on fruit was observed in Dupadal variety at Dupadal. Correlation analysis between mean values of per cent fruit infestation due to M. scyrodes with prevailing major weather parameters during fruiting season of 2021 and 2022 were studied in cv. Konkan Bahadoli. The fruit infestation due to M. scyrodes was negatively correlated with temperature, positively correlated with relative humidity in both the years and M. scyrodes had positive and negative correlation with rainfall during 2021 and 2022, respectively.
