Pheromone-baited traps were used to monitor the movement of the Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Crambidae), through the Texas rice belt from 2000 to 2005. Based on location of discovery in each county and year, the average rate of spread from 1980 to 2005 was 23 km/yr. From 2000 to 2005, the leading edge of the infestation has moved 16.5 km/yr toward Louisiana. The 1.8-fold increase (99% confidence interval) of the area occupied from 2000 to 2005 in the Texas rice belt indicates an expansion of the distribution of E. loftini. If movement continues to occur at similar rates, E. loftini will reach Louisiana by 2008.
2000年至2005年期间，使用性诱捕器监测了墨西哥稻螟Eoreuma loftini (Dyar)（鳞翅目：草螟科）在得克萨斯州水稻种植带的迁飞情况。根据每个县每年发现该害虫的地点，1980年至2005年的平均扩散速度为每年23公里。2000年至2005年期间，虫害前沿以每年16.5公里的速度向路易斯安那州移动。2000年至2005年，得克萨斯州水稻种植带被占领面积增加了1.8倍（99%置信区间），这表明墨西哥稻螟的分布范围在扩大。如果迁飞继续以类似速度发生，墨西哥稻螟将于2008年抵达路易斯安那州。
