Tephritid fruit flies, known as true fruit flies, are globally recognized as one of the most destructive insect pests affecting horticultural crops. In India, and particularly in the Kashmir region, fruit fly infestations are increasingly reported by farmers, leading to substantial yield losses in temperate fruits and vegetables. Despite the economic and quarantine significance of fruit flies, scientific knowledge about the diversity, host range, distribution, and pest status of fruit flies under temperate conditions of Kashmir is extremely limited. The increasing import of fruits and vegetables in the region raises the risk of exotic species introduction, while ongoing climate change further alters pest dynamics and ecosystem vulnerability. The existing cropping systems and agro-climatic conditions of Kashmir differ markedly from other parts of India, making it necessary to understand how Tephritid species interact with local host plants. Therefore, this proposal emerges as a timely scientific response to the need for data driven pest management and biosecurity planning. This study is based on the hypothesis that Tephritid fruit flies have established in the temperate agroecosystems of Kashmir and are becoming an increasing threat to regional horticulture through adaptation and host range expansion. Their growing ability to infest diverse fruits and vegetables reflects shifting pest behavior influenced by ecological changes and human activity. The behavioral flexibility and host plant adaptability have allowed them to exploit temperate crops previously unaffected. This research proposal introduces several novel aspects by integrating classical taxonomy with molecular tools to assess the fruit fly species at the genetic level under temperate conditions. It will be the first regional baseline study to investigate the diversity and host range of Tephritid fruit flies under the unique temperate climatic conditions of Kashmir, where cropping patterns and agroecological contexts differ significantly from tropical regions. Understanding how these pests adapt to new host plants and environmental conditions in Kashmir is essential to predicting their future spread and impact. The study also includes a phytosanitary risk assessment related to the potential introduction of exotic fruit fly species through trade in fruits and vegetables, compounded by the effects of climate change, which may make the region more conducive to their establishment. Furthermore, the research will involve both field-based sampling and laboratory-based validation of species collected from a variety of temperate fruits and vegetables across the diverse agroecosystems of all ten districts of Kashmir. The findings will not only support evidence-based pest management strategies but also strengthen the region’s preparedness against climate driven pest emergence and exotic species incursions, ultimately securing the horticulture sector in Kashmir in the future. This will provide robust scientific evidence on species identity and host associations. The outcome of this research proposal is expected to generate practical and policy relevant information that will benefit both local stakeholders and the broader agricultural system. It will provide a comprehensive inventory of Tephritid species in Kashmir, including both native and potentially invasive types, along with an updated host plant database reflecting their associations with temperate crops. The study will produce spatial distribution maps to visualize their spread across agro-climatic zones and offer a detailed assessment of pest status and economic impact, informing thresholds for effective control. Collectively, these outputs will provide a scientific foundation for managing current infestations and preventing future outbreaks, thereby supporting sustainable horticulture and safeguarding market access in Kashmir.
