江苏太兴县,原来大部为旱作地区,近年来由于水稻面积逐渐扩大,在去年发现有玉米螟为害水稻,而造成枯心苗或白穗的。据调查,太兴镇附近水稻的被害率达2％左右。黄桥周围严重的竟达30—40％。 今年我在太兴公社检查三化螟越冬情况时,也发现有玉米螟在稻根中越冬的,其比例低的2.24％,高的则达11.62％。 从以上情况看,玉米螟为害水稻是新问题值得注意。 Tai Hing County, Jiangsu Province, the original mostly dry areas, in recent years as the gradual expansion of rice area, last year found that corn borer damage to rice, resulting in dead heart seedlings or white spike. According to the survey, the rate of rice damage in Taixing Town is about 2%. Seriously around the yellow bridge up to 30-40%. This year, when I checked overwintering the rice stem borer in Taixing Commune, it was found that there was 2.24% of the corn borer overwintered in the rice root, while the high reached 11.62%. From the above situation, corn borer damage rice is a new issue is worth noting.
