小麦吸浆虫[Srtodiplosis mosellana (Gehin)]分布广,危害大。目前在欧,美、亚三大洲13个国家成为灾害性大的小麦害虫。在国内已遍及20个省、区。我省7个地、市的小麦都曾受害,尤以沿淮阜阳专区的颍上、阜阳、阜南以及宿县专区的灵璧、宿县虫口最多,受害最重。1950年仅阜阳一地即损失小麦1亿公斤,1952年阜阳专区又损失小麦1.1亿公斤以上。后来由于大力推广抗虫品种和防治得力,致使虫口逐年压缩,到60年代已经基本控制为害。70年代人们逐渐放松了对它的警惕,没有再在防治上尽力,结果在80年代初,吸浆虫开始回升,1985年又严重为 Siberian insects [Srtodiplosis mosellana (Gehin)] widely distributed, harmful. At present, 13 countries in Europe, the United States and Asia are the major pests of disasters. In the country has covered more than 20 provinces and autonomous regions. Seven provinces in our province and the city have suffered from wheat, especially Lingbi and Suxian in Yingshang, Fuyang, Funan and Suxian districts along the Huaiyang Fuyang prefecture, with the most victims. In 1950 alone, Fuyang alone lost 100 million kilograms of wheat and in 1952 Fuyang Prefecture lost more than 110 million kilograms of wheat. Later, due to the vigorous promotion of insect-resistant varieties and prevention and control, the population of insects has been compressed year by year. By the 1960s, it had been basically controlled. In the 1970s, people gradually relaxed their vigilance and did not try their best to prevent and control them. As a result, in the early 1980s, the midge of insects began to pick up and again became serious in 1985
