Preliminary studies on leaf beetle, Galeruca daurica on grassland

, : Preliminary studies on leaf beetle, Galeruca daurica on grassland. Chinese Journal of Applied Entomology 49(3): 766-769

Galeruca daurica Joannis is an important leaf-eating pest that has recently serious outbreaks in the Inner Mongolian Autonomous Region. Larvae and adults cause severe damage to plants of the genus Allium, such as A. mongolicum, A. polyrhizum, A. ramosum, etc. It has one generation per year and overwinters as eggs. Its life cycle, habits, occurrence, range, damage symptoms, habitat features and economic impact are described, and strategies of prevention and control discussed.
