Indeed, T. palmi can be mistaken for common thrips species with similar characteristics, e.g. Correct identification to species level can be made only under magnification or with the help of an expert. Morphometric and COI-based identification. Thrips (Thysanoptera) are serious pests and disease vectors on many economically important crops throughout the world [1,2].Identification of most thrips to a species level is difficult because of their small size, subtle morphological differentiation [], intraspecific polymorphisms [], and sexual dimorphisms [].Molecular identification of thrips has major advantages to .

How to Identify Thrips. The thrips Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is an invasive pest that poses a significant economical threat to U.S. agriculture and trade. Most adult thrips are elongate, slender, minute (less than 1/20 inch long), and have long fringes on the margins of both pairs of their long, narrow wings. Keys for identification of common thrips were presented by Palmer et al. PLoS Forty plots were surveyed and DNA extracts of 186 thrips (larvae and adults) were analyzed by multiplex PCR . Methods developed in the Northern Territory to trap thrips with blue sticky‐board traps and water‐tray traps for monitoring purposes and the techniques used for rapid preparation and identification are described. (1989) and Oetting et al. Thrips palmi is a major pest of many crops in the tropics and sub-tropics, and is a serious threat within the protected horticulture industry in other parts of the world including the UK.Widespread use of insecticides against T. palmi throughout the world coupled with the restricted range of products available makes it essential to find alternative systems for control.

Besides damage caused by feeding, it transmits several tospoviruses. Identification of T. palmi at an early stage is crucial in implementing appropriate pest management strategies. Thrips palmi 3 (T. flavus (male): comb incomplete).Strassen (1989) provides an account of characters distinguishing T. palmi from widespread thrips in Europe. Whereas there are a few molecular identification tools for some pest thrips 1,4,6, 9, 24,26 , only F. occidentalis (Pergande) and Thrips palmi Karny can be identified at present using real-time . Thrips palmi identification is hampered by its small size and great similarity with other yellow species of thrips. It is absent from Europe, although outbreaks have occurred in the Netherlands (1988-98), the UK (2000-01) and most recently Portugal (2004). It was named after the director of the Medan quarantine station, Dr BT Palm, and although it has been referred to as 'palm thrips' (CIE, 1986) it is not known to be associated with any palm tree species.One of the first published records of this species as a pest was an account from . DNA barcoding evidenced the presence of cryptic diversity in T.palmi and that warrants exhaustive molecular studies. March.
