Topsoviruses have over 600 plant species hosts. The eggs of the western flower thrips (Frankliniella occidentalis) are laid in leaves, flower petals and in the soft parts of stalks. Whole plant and leaf bioassays were used to compare silver damage of WFT to TG and control plants. Damage Adults and nymphs infest the underside of cotyledons, young leaves and growing points, rasp the plant surface and suck out the cell contents: Adults are 1-2 mm long, and most have a pair of narrow wings fringed with long hairs. is a significant threat to peanuts. thrips (Fig. Western flower thrips, Frankliniella occidentalis P. (Thysanoptera: Thripidae) is a major agricultural and horticulture pest worldwide (Kirk, 2002; Kirk and Terry, 2003). 7). 31, No. or halo spotting. This factsheet provides This factsheet provides information on the pest, the damage it causes to strawberries and the results of AHDB funded research in Projects SF 80, SF 90, SF In the past 30 years, western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), has become one of the most important agricultural pests worldwide. It causes damage and spoilage to a vast number of economically important plant species through feeding, oviposition and spread of several plant diseases, most notably tospoviruses (Morse and Hoddle, 2006 ). Characteristics for to identify onion and western flower thrips from Western flower thrips (WFT) cause significant financial losses for strawberry growers in the United Kingdom. Western flower thrips are slender, very small insects, about 0.03 inch long when mature. They attack leaves, leaf buds, and very small squares, causing a silvering of the lower leaf surface, deformed or blackened leaves, and loss of the plant terminal (Fig. Flower Thrips Flower thrips damage crops through feeding and oviposition, which result in deformation of growing tissues and lead to yield losses in harvested fruits and vegetables, as well as esthetic damage to flowers. , 2015; Reitz Greenhouse thrips and western flower thrips are two common pest species in landscapes. Western flower thrips (WFT) Frankliniella occidentalis continues to be a serious pest of floriculture crops in New England. Shifts in western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae), population abundance and crop damage. Western flower thrips: cotton, navy bean, mungbean, sunflower, canola and peanuts. The six spotted thrips is pale yellow with three dark spots on each of its forewing and the black hunter is black with two clear bands across its wings. Damage. western flower thrips again averaged a significantly higher damage rating(F 91.125, df 1 and 6, P 0.0001) of 3.7 compared with 2.8 for tobacco thrips populations. Since male WFT do Montdorensis predatory mites feed on both thrips and whitefly, and they are proving to be a very effective biological control agent for these pests in protected crops. The most common species of plant-feeding thrips in Texas cotton include flower thrips, onion thrips, and western flower thrips. In Michigan, western flower thrips are most visible as a pest in peach, where late season feeding by thrips results in “silvering” and defuzzing of peaches in the weeks leading up to harvest. Flower thrips damage crops through feeding and oviposition, which result in deformation of growing tissues and lead to yield losses in harvested fruits and vegetables, as well as esthetic damage to flowers (Lewis 1997). 4).
