Abstract
Selected management tactics, including genotype selection, insecticides, and cultural practices, against tobacco thrips and Tomato spotted wilt virus (TSWV) in peanut were evaluated. Insecticide efficacy of thrips control and the impact of TSWV field resistant peanut genotypes on thrips-mediated TSWV transmission and thrips fitness were further investigated. The first objective was to integrate tactics for improved spotted wilt disease management in peanut, including selected insecticides, TSWV resistant cultivars, and cultural practices, namely row patterns and tillage systems. The second objective assessed the effectiveness of insecticides on tobacco thrips mortality and reducing feeding damage over time; the putative resistance status in tobacco thrips from field populations was also evaluated. The third objective focused on the effects of newly released TSWV field resistant genotypes as well as diploid wild species relative of cultivated peanut on thrips transmission and thrips biological fitness.
