Thrips attacks on chili plant lower chlorophyll content and damage the structure of the leaf cells. For instance, a single Tospovirus (Tomato spotted wilt virus) alone caused an estimated $1.4 billion in losses in the U.S. over 10 years. A Better Business Bureau Accredited Business. Chilli thrips are extremely difficult to control, as they are small in size, they reproduce and move quickly and they feed on a broad range of host plants. The goal of this manuscript is to provide a comprehensive and updated list of thrips species that serve as vectors of tospoviruses along with information pertaining to common names, key diagnostic characters, distribution, important crops economically affected, and thrips and Tospovirus-induced symptoms. Seventeen distinct species are established by characteristics such as the host range, vector specificity and amino acid identity of nucleocapsid protein (NP). The manuscript is prepared with special emphasis to the U.S., but information pertaining to other countries is also included. Watermelon silver mottle virus (WSMoV) and Calla lily chlorotic spot virus (CCSV) from Taiwan, Peanut bud necrosis virus (PBNV) and Watermelon bud necrosis virus (WBNV) from India, Capsicum chlorosis virus (CaCV) from Australia, and high temperature-recovered gloxinia tospovirus (HT-1) from the United State were clustered in the same WSMoV serogroup. Thrips attacks on chili plant lower chlorophyll content and damage the structure of the leaf cells. Deformed, crinkly new shoots and leaves as well as brown or gray scars, especially on the bot- tom sides of mature foliage are key evidence. The attacks which was caused by the thrips starting from mild to severe attacks. Thrips-transmitted tospoviruses cause severe yield losses to several economically important crops in the United States and worldwide. Chilli thrips: Scirtothrips dorsalis Symptoms of damage: The infested leaves develop crinkles and curl upwards; Elongated petiole; Buds become brittle and drop down; Early stage, infestation leads to stunted growth and flower production, fruit set are arrested The study was conducted by observing the attacks of thrips on the leaves chili plant. Observations were carried out at the part of affected leaves, color, shape and location of the attack, leaf structure, chlorophyll content and the content of nitrogen, fats and carbohydrates of affected leaves.
