Frankliniella intonsa Trybom (Thysanoptera: Thripidae) is an economically important species owing to its polyphagous nature and potential role as a vector of tospoviruses. During fixed-plot surveys conducted from November 2023 to April 2024 at the C-Block Farm of Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India, specimens of thrips were collected from tomato (Solanum lycopersicum L.) flowers using the ‘beat and jerk’ technique. Collected specimens were preserved, slide-mounted, and identified following standard taxonomic protocols and available identification keys. Three female specimens were examined and confirmed as F. intonsa based on characteristic morphological features, including an 8-segmented antenna with forked sensoria on antennal segments III and IV, ocellar setae III arising within the ocellar triangle, presence of ctenidia on abdominal tergites V–VIII, and a complete postero-marginal comb of microtrichia on abdominal tergite VIII. The occurrence of F. intonsa on tomato represents the first confirmed host record of this species from tomato in West Bengal and expands its known host range in India. This finding also contributes to the distributional knowledge of the species in the Lower Gangetic Plains, where it has not previously been documented on this crop. Considering the economic importance of tomato and the known pest status of F. intonsa elsewhere, further studies are required to assess its population dynamics, pest potential, virus-vector status, and implications for integrated pest management in tomato-based agro-ecosystems in eastern India.
