稻蓟马Stenchaetothrip biformis(Baghall,1913)是我国南、北主要稻区(约18—34°N)水稻前期的主要害虫,近年来危害加重,因此在稻田期及本田分蘖期不得不用农药压低虫口密度,以确保稻苗早发快长。若能采用抗性品种,减少水稻前期用药次数及用量,这是水稻害虫综合防治中值得提倡的措施。目前国外,如印度和孟加拉国对抗稻蓟马品种的筛选已进行了一些工作,并筛选出了一批具有抗性的水稻品种和品系。我国水稻品种资源丰富,是否有抗稻蓟马的抗源存在,尚未见到这方面的报道。1982年我们利用我院农学系收集的八百余个水稻材料中的244个进行了初筛,以期对筛选的方法、标准等进行探讨。
Stenchaetothrip biformis (Baghall, 1913), a major pest in the early and late rice paddy fields of southern and northern China (about 18-34 ° N), has become more and more harmful in recent years. Therefore, Density, to ensure that rice seedlings grow faster and longer. If resistant varieties can be used to reduce the number and dosage of rice prophase drugs, which is worthy of promotion in rice pest integrated control measures. At present, foreign countries, such as India and Bangladesh, have conducted some work on the screening of varieties of rice thrips and have screened a number of resistant rice varieties and lines. China’s rice varieties rich in resources, there is resistance to anti-rice thrips exist, have not yet seen this report. In 1982, we used 244 of more than 800 rice materials collected by Department of Agronomy of our hospital to conduct preliminary screening in order to discuss the screening methods and standards.
