The incidence of fruit borer and fruit flies started in second week of August and first week of October respectively. The borer activity reached high from second week of November to the end of January. Whereas, high incidence of flies noticed from November to third week of January. Among the eight varieties of ber screened, Illaichi recorded lowest infestation and is considered as moderately resistant against fruit borer and fruit flies. Umran recorded highest infestation of fruit borer while Sanaur-2, Umran, kadaka and Sanaur-6 were moderately susceptible to fruit flies infestation. Umran recorded maximum of 5 fruit borer larvae per fruit while Sanaur-2 had recorded maximum of 10 larvae of fruit flies per fruit. Increase in the fruit size resulted in the increase of oviposition by both the pests. Maximum emergence of adults was observed when pupae were at a depth of 2 cm below soil and loss due to fruit borer and fruit flies together was found to vary from 70.81 to 71.28 with an average of 71.05 per cent. The maximum loss due to damage by borer was 42.92 and that by flies was 28.12 per cent. Monocrotophos 36 SL was found effective against fruit borer and the same with jaggery was effective against fruit flies and NSKE 5% was found effective among botanicals in reducing the pest infestation and for effective control of pests three sprays at 12,14 and 16^ week after 50 per cent flowering was more economical. The residues of the chemicals after the last spray were below the tolerance limit."ennullThesis
