In 2006 the hot and dry conditions experienced in mid-summer led to increased populations that were very difficult to control in some areas. Furthermore, many of the earlier registered products for control of onion thrips are loosing control efficacy. Onion thrips insensitivity to λ -cyhalothrin (Warrio...
متن کاملEffects of Spinosad and Acephate on Western Flower Thrips Inside and Outside a Greenhouse

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 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...
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...
