Effects of Spinosad and Acephate on Western Flower Thrips Inside and Outside a Greenhouse
Greenhouse studies were conducted from 1996 to 1998 to determine the efficacy of spinosad, and acephate, against western flower thrips (Frankliniella occidentalis Pergande) on transvaal daisy (Gerbera jamesonii H. Bolus ex. Hook f). In addition, the number of natural enemies inside and outside the greenhouse was determined. Studies were arranged in a randomized complete-block design with four b...
متن کاملImpacts on Natural Enemies and Competitor Thrips of Insecticides against the Western Flower Thrips (Thysanoptera: Thripidae) in Fruiting Vegetables
Newer, selective insecticides with few negative impacts on natural enemies and competitor species are needed for effective, sustainable management of the western flower thrips, Frankliniella occidentalis (Pergande). The purpose of this study was to evaluate the impacts on natural enemies and competitor thrips species of insecticides used for control of western flower thrips in fruiting vegetabl...
متن کاملOptimizing Western Flower Thrips Management on French Beans by Combined Use of Beneficials and Imidacloprid
Western flower thrips (WFT), Frankliniella occidentalis (Pergande), is an important pest of vegetable crops worldwide and has developed resistance to many insecticides. The predatory mites Neoseiulus (=Amblyseius) cucumeris (Oudemans), the entomopathogenic fungus Metarhizium anisopliae (Metsch.), and an insecticide (imidacloprid) were tested for their efficacy to reduce WFT population density a...
متن کاملInfluence of Prey Availability and Induced Host-plant Resistance on Omnivory by Western Flower Thrips
Theory predicts that the balance of nutritional needs, food availability, and the quality of particular food items are important factors in the feeding decisions of omnivorous animals. In this study we investigate factors that affect the feeding decisions of an omnivorous thrips (Frankliniella occidentalis) that eats both animal prey and plant foliage. In the presence of prey (mite eggs), adult...
متن کاملEffect of sugar spraying on host plant resistance to western flower thrips in tomato
Sugar spraying can cause induced plant resistance. In this study we investigated the effects of sugar spraying on the resistance to western flower thrips, WFT, Frankliniella occidentalis on tomato. We tested three different sugars: sucrose, fructose and glucose, at four concentrations: 0, 1, 10 and 100 ppm, to induce resistance of the cultivated tomato (var. Moneymaker). Bioassays conducted 2 w...
