“…B. minax had been reported from Southern China, India (including West Bengal and Sikkim), and Bhutan (Drew et al, 2002). Whereas Laskar et al, (2016), reported that both B. minax (Enderlein) and B. dorsalis could be recovered from mandarin in orchards of Darjeeling district of West Bengal. The present study though confirmed widespread occurrence of fruit fly in mandarin at Darjeeling and Kalimpong districts but fruits were unexceptionally infested by B. minax only.…”

“…The obtained result on extent of damage was in conformity with Wang et al, (1995); Nie et al, (1999) and Dorji et al, (2006) who reported that the Chinese citrus fly, B. minax, an oligophagous pest causing more than 50% yield loss and occasionally it could be upto 100%. Earlier Kumar et al, (2015) identified the fruit fly as Bactrocera dorsalis and Laskar et al, (2016) reported a mixed population of B. minax and B. dorsalis recovering from mandarin orange of Darjeeling district, West Bengal. The finding of the present study did not confirm it.…”

“…However, the effective production of these crops in the region is severely hindered by pests and crop illnesses. In this group of pests, tephritids are identified globally as a severe risk to the agriculture sector, including India [1,2,3]. The Tephritidae family has about five thousand species [4].…”

The Lower Gangetic Plains are India's central horticultural crop production regions. Fruit flies (Diptera: Tephritidae) are a significant insect pest that significantly hinders the effective crop production of various commercially valuable fruit and vegetable crops. Therefore, rapid and precise species identification techniques are essential to controlling, managing, and quarantining these pests. Furthermore, reliably identifying fruit flies is exceedingly challenging due to their striking resemblances in morphological characters. In this work, we investigated the effectiveness of mitochondrial cytochrome c oxidase I (COI) gene sequences for identifying seven fruit fly species, involving only the genus Bactrocera from the lower Gangetic Plains in eastern India. The sequences of the studied species showed 99%–100% similarity with sequences from within and outside the country. COI barcodes were able to distinguish between species, with K2P intraspecific genetic divergences ranging from 0-1% and K2P interspecific genetic divergences ranging from 3.65-28.46%, thus maintaining a proper barcode gap. Phylogenetic analyses were performed, and the results showed moderate to high supported monophyly among species. Therefore, COI barcodes have proven a highly successful alternative for quickly identifying fruit flies. This is also the first account of molecular identification of the previously reported tephritid fruit flies infesting fruits and vegetables in eastern India's agriculturally important lower Gangetic Plains.

Fruit flies are the most serious economic insect pests of mango in India and other parts of the world. Under future climate change, shifts in temperature will be a key driver of ecosystem function especially in terms of insect pest dynamics. In this study, we predicted the voltinism of the three economically important fruit fly species viz., Bactrocera dorsalis (Hendel), Bactrocera correcta (Bezzi) and Bactrocera zonata (Saunders) of mango from 10 geographical locations in India using well established degree day approaches. Daily minimum and maximum temperature data were generated by using seven General Circulation Models (GCMs) along with their ensemble, in conjunction with the four representative concentration pathways (RCPs) scenarios (RCP 2.6, RCP 4.5, RCP 6.0 and RCP 8.5) and three time periods (2020, 2050 and 2080) generated from MarkSim® DSSAT weather file generator. Historical data from 1969–2005 of these 10 locations were considered as baseline period. Under future predicted climates, model outputs indicates that all three fruit fly species will produce higher number of generations (1–2 additional generations) with 15–24% reduced generation time over the baseline period. The increased voltinism of fruit fly species due to increased temperature may lead to ≃5% higher infestation of mango fruits in India by the year 2050. Analysis of variance revealed that ‘geographical locations’ explained 77% of the total variation in voltinism followed by ‘time periods’ (11%). Such increase in the voltinism of fruit flies and the consequent increases in the infestation of mango fruits are likely to have significant negative impacts on mango protection and production.
