The highest infestation was observed in case of oriental fruit fly, Bactrocera dorsalis (Hendel) (i.e. 15 maggots/5fruits) after that mealybug (4 adult/5 branches) were observed in Hissar Surkha. The maximum number of oviposition marks oriental fruit flies were observed on Hissar Surkha (i.e. 19 oviposition marks/5 fruits) followed by Banarasi Surkha, Allahabad Safeda (16 oviposition marks/5 fruits) and Punjab pink (15 oviposition marks/5 fruits) whereas minimum observed in Lalit (8 oviposition marks/ five fruits). In case of Hybrid guava, Strawberry Guava and Chinese Guava no infestation was observed. In case of capsule borer maximum was observed in Hissar Safeda (8 larva /5fruits) whereas no infestation was observed in Kg Guava, Pant Red, Sarbati, Barafkhana and Lalit.
