通过2003~2004年对稻水象甲(Lissorhoptrus oryzophilus Kuschel)在山西忻州地区危害特点,发生规律和生物学特性进行研究。结果表明:稻水象甲在该地区一年只发生一代,以成虫在土中越冬,营孤雌生殖方式繁衍后代,扩展蔓延迅速,继而提出针对性的防治策略和具体措施。
The characteristics of the damage, the occurrence and the biological characteristics of Lissorhoptrus oryzophilus Kuschel in Xinzhou of Shanxi Province from 2003 to 2004 were studied. The results showed that the rice water weevil only took one generation a year in this area, with the adults overwintering in the soil and the progeny parthenogenesis multiplying their offspring, which expanded and spread rapidly, and then put forward the specific control strategies and concrete measures.
