螟虫是水稻上的主要害虫,严重影响产量,是当前农业生产上亟待解决的问题。但因稻区辽阔,耕作制度复杂,水稻品种繁多,加以气候年复不同,而3种螟虫的生物学特性各异,发生早迟,为害现象亦不甚一致,且分布情况又极错综,所以造成防治上的困难。我国许多学者曾经多年的研究,对三化螟还有一套较成熟的防治方法;但对二化螟尚少系统研究。二化螟系杂食性,且具有抵抗和适应外界环境的顽强性,它能从稻根中向外逃逸。目前从其生活习性上观察研究,获得一些防治的途径,如高割低割、秋耕秋耙等结合综合性的农业技术措施,并在秧田,本田适当采用666,或根据一定条件插菸绳、菸茎作为辅助方法,以达到减轻螟
Stem borer is a major pest on rice, seriously affecting the yield, is the current agricultural production problems to be solved. However, due to the vast area of rice, the tillage system is complicated, the variety of rice is varied, and the climate is different from year to year. However, the biological characteristics of the three kinds of stem borers are different, and the occurrence of the disease is not yet uniform and the distribution is very complicated. Cause prevention and treatment of the difficulties. Many scholars in our country have studied for many years, there is a more mature control method for Borer. However, there is still little systematic study on Borer. Chilo suppressalis is omnivorous and resistant and adaptable to the external environment, it escapes from the roots of rice. At present, we observe and study from their habits and get some ways of prevention and control, such as high cutting and low cutting, autumn harvesting with rake and other comprehensive agricultural technology measures, and 666 in seedling and Honda, or inserting tobacco ropes under certain conditions , Tobacco stems as an adjunct to achieve mitigating stem borer
