Abstract: The turfgrass insect pest Spodoptera mauritia, is distributed in the south of China. It is polyphagous and Agrostis stolonifera is one of its turfgrass hosts. Field observations and experimental rearing methods were used to study the biology of S. mauritia fed on this turfgrass. In the field, the larvae could chew the turfgrass leaves and tender stems, causing severe damage. The weight of female pupae was greater than that of male ones. The highest productivity per female was 251 eggs, while the average productivity per female was 54.6 eggs. The eggs appeared in clusters when laid.
