Screening of Pumpkin (cucurbita Sp.) Germplasm for Sources of Resistance against Melon Fruit Fly (bactrocera Cucurbitae)

Fifty seven pumpkin (Cucurbita sp.) genotypes from the germplasm maintained at Vegetable Department of K.R.College of Horticulture, Arabhavi were screened for resistance against melon fruit fly under natural epiphytotic conditions on the bases of per cent fruit infestation. Arka Suryamukhi was categorized as highly resistant genotype with less than 10 per cent fruit infestation. The genotypes, KP-3, KP-19, KP-32 and KP-38 showed 10-20 per cent fruit infestation and were categorized as resistant genotypes. It was concluded that Arka Suryamukhi, KP-3, KP-19, KP-32 and KP-38 can be used as source of resistance for developing pumpkin genotypes resistant to melon fruit flies.
