河南省小麦吸浆虫自1949年在南阳专区邓县、新野等处开始发生,1950年经调查证明,除南阳专区外,潢川、信阳、洛阳、淮阳等专区亦有发生,1951年又发现于陕州和许昌专区。到1952年全省受害的已达7个专区、44个县和1个市郊,受害重的地区减产50—90％,成为小麦减产的主要因素。经南阳小麦吸浆虫研究站连续两年的研究,用人工捕打,药剂喷治,均有相当效果,农业和生物防治亦获初步线索。兹分别介绍于次:
In 1949, wheat midge in Henan Province started to take place in Dengxian County and Xinye County in Nanyang Prefecture. In 1950, surveys showed that in addition to Nanyang Prefecture, Huangchuan County, Xinyang County, Luoyang County and Huaiyang Prefecture also occurred. In 1951, Shan area and Xuchang area. By 1952, the number of affected areas in the province had reached 7 prefectures, 44 counties and 1 suburb, and the areas hit hardest by weight loss by 50-90% became the major factor in reducing wheat output. Nanyang Wheat Midge Research Station for two consecutive years of research, with artificial catching, spraying agents, have a considerable effect, agriculture and biological control also received preliminary clues. Hereby introduced at:
