Analysis of Wing Forms and Dominant of Thrips nigropilosus Uzel (Thysanoptera: Thripidae) Inflicting to Cnidium officinale Makino

Background: The study aimed to investigate its wing forms and dominant species of thrips inflicting C. officinale.BRMethods and results: T. nigropilosus was collected by the biting method in a total 17 different cultivation sites during 2020 - 2022 and the species was identified by stereo microscope. A Total eight species including T. nigropilosus, T. tabaci, Haplothrips chinensis, Frankliniella intonsa, T. palmi, Microcephalothrips abdominalis, F. occidentalis and Anaphothrips obscurus were identified in four and thirteen cultivation sites in 2020 and 2022, respectively. T. nigropilosus was the more abundant species than T. tabaci. Their wing form was divided into macropterous (long-winged) and brachypterous (short-winged) and the macropterous individuals were dominant than brachypterous.BRConclusions: The dominant species is chrysanthemum thrips, Thrips nigropilosus and it has two wing forms discriminated as macropterous and brachypterous.
