粟芒蝇是我国北方谷子的重要害虫,常造成枯心、白穗、畸型穗等,严重影响谷子产量,尤以夏播谷地区受害较重。1986～1990年作者等对华北地区4057份粟品种进行了抗性鉴定,结果表明,以被害指数为鉴别抗感依据,品种间对粟芒蝇的抗性有明显差异,中抗级以上品种占3.11%,感和高感品种占96.89%,从中选出一些抗性表现稳定的品种,可为选育抗虫品种提供抗性材料。 Sumatras flies are important pests of millet in the north of our country, often resulting in dry heart, white spike, deformed spike and so on, which seriously affect the yield of millet, especially in the summer sowing area. From 1986 to 1990, 4057 millet cultivars in North China were tested for resistance. The results showed that there was a significant difference in the resistance between cultivars to S. sumatrans, 3.11%, 96.89% of the susceptible and susceptible breeds, from which some varieties with stable resistance can be selected to provide resistant materials for breeding insect-resistant breeds.
