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 /plant, which indicated that flowers and fruits were higher in number during rainy season. However, the weights of fruits were higher in winter season as compared to rainy. The number of fruits drop were recorded higher in rainy season about 7.72 % in normal planting (NP) and 8.85 % in high density planting (HDP) during  first year study (2013). In second year of study (2014), the damages were of rainy season 7.25 % and 8.49% in NP and HDP, respectively. The maximum and minimum winter losses (2013) were 7.50 % and 5.02% in NP and HDP planting, respectively. Furthermore, identification of fruit fly species was studied at Patna and Ranchi during 2014, simultaneously. It has been found that Bactrocera 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 B. correcta  was trapped more (47.25%) followed by B. zonata, B. dorsalis and B. cucurbitae in the same season in ICAR-RCER, Ranchi.
