芦笋十四点负泥虫发生规律与防治技术初探

Preliminary Study on the Occurrence Regularity and Control Techniques of Crioceris quatuordecimpunctata (Scopolic)

十四点负泥虫是北京市新发现的一种为害芦笋的害虫。通过田间观察试验,了解了该虫的形态特征和生物学特性,明确了在北京地区一年发生3～4代,提出了应用农业防治、生物防治和化学农药防治等控制该虫的方法。

Crioceris quatuordecimpunctata （Scopolic） is a newly found pest in Beijing which attacks asparagus. We made clear of the morphological and biological characteristics of this pest according to lots of field experiments. Furthermore, we got the conclusion that there are 3 to 4 generations per year for this pest. Finally, we put forward some concrete control methods relating to agricultural, biological and chemical control.
