摘要
Locust Heaven Locust outbreaks have severe consequences for agriculture, but the conditions that promote an outbreak are unknown. Cease et al. (p. 467 ) investigated aspects of the locust diet and found that increased nitrogen content of cereal grasses reduced the size and viability of a herbivorous locust species. This locust prefers low N plants, which result from heavy grazing by livestock and erosion.
