Population dynamics of fruit flies Bactrocera dorsalis Hendel and B. correcta Bezzi were studied in mango ecosystem at Veppalampatti location in Krishnagiri district of Tamil Nadu from October 2017 to September 2018. The fluctuations in the occurrence of adult fruit flies were assessed by methyl eugenol trap catches at fortnight intervals in fixed locations. The results revealed that B. dorsalis reached the first peak (116.00 flies/ trap) in first fortnight of June, 2018. Relatively, the initial counts of B. correcta was maximum and the first peak (195.00 flies/ trap) was observed during first fortnight of October, 2017. Correlation of trap catches with weather parameters revealed that B. dorsalis trap catches were influenced to an extent of 63%, whereas B. correcta occurrence was correlated with rainfall only.

Population dynamics of fruit flies Bactrocera dorsalis Hendel and B. correcta Bezzi were studied in mango ecosystem at Veppalampatti location in Krishnagiri district of Tamil Nadu from October 2017 to September 2018. The fluctuations in the occurrence of adult fruit flies were assessed by methyl eugenol trap catches at fortnight intervals in fixed locations. The results revealed that B. dorsalis reached the first peak (116.00 flies/ trap) in first fortnight of June, 2018. Relatively, the initial counts of B. correcta was maximum and the first peak (195.00 flies/ trap) was observed during first fortnight of October, 2017. Correlation of trap catches with weather parameters revealed that B. dorsalis trap catches were influenced to an extent of 63%, whereas B. correcta occurrence was correlated with rainfall only.
