Abstract: 

The seasonal incidence of Sapota bud borer, Anarsia achrasella Bradley Gelechidae: Lepidoptera infesting sapota Manilkara achras (Mill.) Forsberg was carried out in sapota DHS-2 hybrido rchard of KVK, Saidapur farm, Dharwad, University of Agricultural Sciences, Dharwad, Karnataka, India during 2013 June–2014 May. Incidence of sapota bud borer revealed that the bud borer was active throughout the year with peak period of infestation 11.54 % in second fortnight of March and lowest of 1.27 % in second fortnight of October. Pest incidence was more during dry period (December to June) and less during remaining season (July to November).A study on correlation of bud borer with weather parameters indicated that there was a significant and positive correlation between bud borer damage and maximum temperature. Rest of the weather factors had no influence on pest population during the period of study.
