为了探明稻水象甲在汨罗市的发生规律，明确其危害情况，并提出相应防控策略，于2006~2013年对汨罗市的田间稻水象甲消长动态进行了系统调查。结果表明：稻水象甲在汨罗市一年发生1~2代，主要以成虫在沟渠及山坡杂草茂密处和灌丛下表土层越冬，以幼虫蛀食稻根，直接影响植株的生长发育和稻谷产量，造成水稻产量损失率在21.57%~60.00%之间，对水稻安全生产构成严重威胁。在此基础上，提出了掌握发生规律，加强虫情监测；采取防控措施，控制扩散蔓延等防控策略。

In order to determine the occurrence regularity and damage situation of Lissorhoptrus oryzophilus Kuschel in Miluo city and to propose corresponding control strategies, a systematical investigation had been conducted to the dynamics of Lissorhoptrus oryzophilus Kuschel in Miluo city from 2006 to 2013. The results showed that Lissorhoptrus oryzophilus Kuschel occurred 1~2 generations in Miluo city, of which the adults mainly overwinter in the ditches, dense weed in side-hill and surface soil under shrub; its larvae eat rice roots, thereby directly influencing the plant growth and grain yield of rice, which can cause the loss of rice yield by 21.57%~ 60.00%. Therefore, Lissorhoptrus oryzophilus Kuschel threatened the safety of rice production seriously. Then, some control strategies were put forward, including understanding occurrence regularity, strengthening insect infestation monitoring, applying control measures, and controlling diffusion.
