Abstract/Contents: | "The impact of fall army worm (FAR), Spodoptera frugiperda (J. E. Smith) feeding on the quality and yield of bermuda grass, Cynodon dactylon (L.) Pres., cv. Coastal, was determined. Yield losses of Coastal were 0.5 to 1.1 metric ton/ha when artificially infested with population densities of 1.1 to 9.9 larvae per 0.1 m2. Feeding by FAR also resulted in lower yields of digestible dry matter (245 kg/ha) and crude protein (72 kg/ha) in Coastal. An economic injury level of 8 FAR larvae per 0.1 m2 for Coastal was calculated based on a hay price of $54 per metric ton and cost of control of $6.74 per ha. From these data, an economic threshold of four fourth and fifth in stars per 0.1 m2 was determined for Coastal." |
