abstract
India is the largest producer of mangoes (Mangifera indica) with 44.14% of the total world production, continues to dominate the Indian fruit basket contributing 36% to total fruit area and 20.30% to total fruit production. In Telangana State, mango occupies 22% of total area under fruits comprising 1.2 million hectares. Mango is being exported from the State but affected by different species of fruit flies. Studies were carried out in Ranga Reddy district of Telangana state, India during the year 2018 and 2019 (two seasons) to find out species diversity of fruit flies that are damaging the important mango varieties like Banginapalli, Dasheri and Himayat. The surveillance was conducted using bottle traps with methyl eugenol as attractant. The results revealed that significant population of two species of fruit flies belongs to Genus Bactrocera namely; Bactrocera dorsalis and B. zonata were trapped in all the three varieties. In variety Banginapalli significantly highest number of 190.60 ± 12.51 fruit flies were trapped and followed by 67.20 ± 3.77 in Dashehari and 62.60 ± 5.99 in Himayat variety during 2018. Similarly, significantly higher number of fruit flies were trapped in Banginapalli (90.80 ± 15.81) followed by Dasheri (31.50 ± 4.75) and Himayat varieties (20.20 ± 4.26) during the year 2019. Among the two species, the oriental fruit fly, B. dorsalis was found dominating other species in Banginapalli variety whereas peach fruit fly, B. zonata found dominating in Dasheri and Himayat varieties during both years. Timely management through cultural, chemical and use of para pheromone lures as an area wide management strategy can reduce the fruit fly damage in mango.
