螟虫工作者对于掘稻根治螟有不同的看法:有的从理論出发,認为有效;有的从实践出发,認为无效。由于看法不同,就产生了观点上的分歧,以致成为屡次稻螟会議上爭論不休的問題,直到如今尚未得出正确的結論。今就这个問題提出我們的看法如下。三化螟在中国系单食性害虫,只寄生于水稻,而不寄生于其他植物上。据我們的研究,三化螟有95%在稻根中越冬,其余5%在稻草中越冬的,多因干燥而死亡。因此,从理論上講,掘稻根就能够消灭螟虫。同时,在太湖流域有几百万亩晚播晚栽(“小滿”播种、“夏至”栽秧)的稻区,促使第一代三化螟不易在秧田中产卵,也就消灭了第一代三化螟;到第三代时,这个广大的地区没有螟灾,称为无螟害区。1950年在江苏无錫
Stem borers have different views on the rice stemming borers: some are valid from the theory, and some are invalid from the practice. Due to different views, they produced divergent views and became the subject of repeated disputes over the rice borer conference until now no correct conclusion has been reached yet. Our views on this issue are as follows. Borer in China is a simple pest, parasitic only in rice, but not parasitic on other plants. According to our study, 95% of the stem borer overwintered in the rice roots and the remaining 5% overwintered in the straw, mostly due to dryness. Therefore, in theory, digging rice roots can eliminate stem borers. At the same time, in the Taihu Lake Basin, there are several million mu of late sowing late planting (“Xiaoman” sowing, “Summer Solstice” planting) of rice, prompting the first generation of three borer is not easy to spawn in the seedling, also eliminated the first On behalf of the three rice borer; to the third generation, this vast area without borer disaster, known as non-stem borer area. 1950 in Wuxi, Jiangsu
