Using of resistant varieties is one of the effective, ecofriendly components of IPM for fruit flies due to the difficulties associated with biological and chemical control methods. Twenty five muskmelon genotypes were screened under field conditions at College of Horticulture, Anatharajupeta during rabi 2017-18 and 2018-19 and were grouped into different categories based on % fruit infestation. Among the screened genotypes, five genotypes, IC 315330P2, IC 321378, NMMH-24, Suvarna, IC 321327 were grouped under ‘Resistant’ category; eleven genotypes, Sharbath-e-nara, Patasha, IC 321333P2, IC 321323, Papayee-3, IC 321376, IC 321328, IC 321368, IC 321376, Papayee-sel, Sirangi were grouped under ‘ Moderately Resistant’ category; Eight genotypes, Trisha-2, Alpur orange, NCSL, Allanagaram, IC 321343, KSP 1060, Amul-9, Sharbath were grouped under ‘Suceptible’ category and the only genotype grouped under ‘Highly Susceptible’ category was Papasa. Further it can be concluded, that the resistant genotypes identified through this study can be made use of as sources of resistance in breeding programme for development of fruit fly resistant varieties of muskmelon.
