Abstract:

Incidence of fruit fly and damage intensity in guava (Psidium guajava L.) in orchards of Eastern India, Ranchi were studied during rainy and winter season in 2013 and 2014 under ICAR-RCER. The observations were recorded on number of flowers and fruits per plants, indicated that flowers and fruit were higher in number in rainy season. However, the weights of fruits were high in winter season as compared to rainy. The number of fruits drop were recorded higher in rainy season about 7.72 % in normal planting and 8.85 % in high density planting in first year study (2013). In second year of study, the damage were 7.25 % and 8.49 % in normal planting and high density plating, respectively. The maximum and minimum winter losses (2013) were 7.58 % and 5.02% in normal planting and high density planting, respectively. Furthermore, identification of fruit fly species were studied at Patna and Ranchi during 2014 simultaneously. It has been found that Bractocera zonata was trapped more (83.00%) in rainy season as compared to other species ( B.dosalis, B. cucurbitae and B.tau ) at ICAR-RCER Patna, India, whereas Bractocera correcta trapped more (47.25%) followed by B. zonata , B. dorsalis and B. cucurbitae in the same season in ICAR-RCER, Ranchi.
