| Abstract/Contents: | "St. Augustinegrass [Stenotaphrum secundatum (Walter) Kuntze] is a warm season grass mainly grown in the southern coastal states. It is known for growing well under full sunshine as well as moderate shade, and for being a fast growing turfgrass. However, it is prone to thatch accumulation, increasing insect and disease problems. Among insect pests, the Southern Chinch Bug (Blissus insularis Barber; SCB) is the most economically important one for this turfgrass species. SCB feeds by sucking the plants sap, eventually damaging or killing whole lawns. The frequent use of insecticides applied to control SCB has helped this insect to evolve resistance. For this reason, alternative integrated control tactics are needed. Development of tolerant and resistant cultivars is of great value to reduce reliance on insecticides and maintain turf quality. Greenhouse experiments were conducted to evaluate the performance of a set of St. Augustinegrass breeding lines alongside resistant and susceptible cultivar checks . The plants were exposed to a high infestation of SCB for six weeks to quantify percentage damage, functional plant loss index (FPLI) and insect survival. In addition, feeding and ovipositional preference of the chinch bugs were evaluated by exposing five males and five females to a single stolon of each genotype for a period of three weeks. Results of these experiments identified significant differences among genotypes on damage susceptibility and potential for SCB survival and reproduction. This information will be used to design efficient phenotyping and crossing strategies to identify and develop new St. Augustinegrass cultivars with genetic resistance to SCB." |
