Extensive surveys were conducted to assess the ecological status, biology, and molecular taxonomy of the fruit fly Bactrocera dorsalis, which is associated with Ber (Ziziphus jujube Mill) plantations in the Solapur district of Maharashtra. The survey encompassed 20 different Ber plantation fields across various regions of Solapur district and was carried out from October 2023 to February 2024. Most observations were made during the winter season, coinciding with the fruiting period. Bactrocera dorsalis, known as the Oriental fruit fly, has been identified as a highly destructive and economically significant invasive polyphagous pest in agricultural fields. To mitigate potential losses for farmers, it is crucial to implement rapid surveys, accurate species identification, and immediate control measures. Failure to address these issues could result in substantial crop damage. In light of this, our study aims to provide accurate identification and a comprehensive understanding of the ecology and biology of Bactrocera dorsalis.
