Biological characteristics of asparagus beetle: Crioceris quatuordecimpunctata (Scopoli)

Hai-min Jia, Ju-ying Zhao, He-tian Jia, Dan Chen
Crioceris quatuordecimpunctata (Scopoli), the asparagus beetle, is one of the most important pests on asparagus. With increasing asparagus acreage in China, a better understanding of its life cycles is required. Adult asparagus beetles overwinter in the soil and begin to emerge to harm young asparagus and mate to lay eggs in early April of the following year. The activity of the pest intensifies as temperatures increase during the day and adults return to the soil toward evening. There are generally 3 to 6 generations of beetles each year. In this paper, the morphology, life habits and occurrence regularity of Crioceris quatuordecimpunctata are described and reported.
