摘要
对稻水象甲的生物学特性及几种杀虫剂对稻水象甲的防治药效进行了研究,结果表明:稻水象甲在宁德市1 a发生2代,双早秧田(4月下旬至5月初)、本田(5月上旬至中旬)是越冬成虫防治关键时期,田间防治以5%氟虫腈1200倍液为佳.
Lissorhortrus oryxzophilus Kuschel is a major pest of quarantine significance. With its broad adaptability, high reproductive ability, it is difficult to control and manage it. In this study, the experiments on the biology of the pest and its control effects with different insecticides were conducted in Ningde City, Fujian Province. The results showed that there were two generations of the pest occurring per year in Ningde. The key periods for controlling this pest effectively were during late April and early May, and during early and mid May （for overwintering adults）. Fipronil was considered the most effecitve insecticide to control this pest in fields
