Fruit flies belonging to the family Tephritidae are the major biotic stress on various fruits and vegetables around the world. Among them, Bactrocera, Dacus and Zeugodacus species are widely distributed and cause significant economic losses. An extensive survey was undertaken from October 2018 to September 2019 in the agro-climatic region of the North Eastern region of Karnataka comprising six districts to profile the distribution of tephritid fruit fly species. Six fruit fly species viz., Bactrocera dorsalis, B. correcta, B. zonata, Zeugodacus cucurbitae, Dacus ramanii and D. discophorus were observed. Among the B. dorsalis complex, B. dorsalis (87.15%) was the predominant species and was active throughout the period of surveillance at all locations. Bactrocera correcta (3.53-6.70%) was the second most dominating species followed by B. zonata (1.06-3.75 %). Higher diversity of fruit flies was recorded in Bidar followed by Raichur and Ballari. The peak fruit fly population was observed from October 2018 to March 2019 and gradually decreased from April 2019 onwards till June 2019. The correlation analysis showed a significant negative correlation between temperature and rainfall, whereas significant positive correlation with relative humidity (RH) in Bidar, Yadgir and Koppal districts. The occurrence of fruit fly incidence was influenced by environmental factors as well as host availability in studied locations. [ABSTRACT FROM AUTHOR] |
