玉米是云南省主要粮食作物之一。近年种植面积1420余万亩,总产249万余吨,居全省粮食作物总产第2位,但因遭受玉米螟为害,常年损失5%~10%,严重者达30%.为减轻螟害,提高玉米的产量和品质,以增加我省粮食总产,发展畜牧业和提供轻工业原料的需要,特列题开展对玉米螟的研究。现将1988年研究情况概述如下: 长期以来,我国各地普遍发生、对玉米为害严重的优势种一直沿用欧洲玉米螟的学名Pyrausta nubilalis Huber,1970年以后,国际上将Pyrausta属改为Ostrinia属,我国玉米螟的学名随之改用Ostrinia nubilalis(Huber)。1970年,日本人六蒲晃和加拿大人门罗发表了“欧洲玉米螟及其近缘种的分类与分布”的研究报告,指出欧洲玉米螟D.nubilalis(Huber)只分布欧洲、西北非、亚洲西部,已传到美洲北部,而在亚洲东
Corn is one of the main food crops in Yunnan Province. In recent years, planting area of more than 1420 mu, with a total output of more than 2,490,000 tons, ranking second in the province’s total output of food crops, but due to the damage caused by corn borer, perennial loss of 5% to 10%, a serious 30% Harm, improve the yield and quality of corn, in order to increase the province’s total grain output, the development of animal husbandry and the need to provide light industrial raw materials, special issue to the corn borer research. The research situation of 1988 is summarized as follows: For a long time, the prevalence in our country, the dominant species of serious damage to corn has been using the scientific name of the European corn borer Pyrausta nubilalis Huber, after 1970, the international Pyrausta genus Ostrinia genus, China Ostrinia nubilalis (Huber) was subsequently replaced by the scientific name of the corn borer. In 1970, the Japanese Liu Pu Ao and Canadian Monroe published the “European corn borer and its relatives classification and distribution” report, pointed out that the European corn borer D.nubilalis (Huber) only distributed in Europe, Northwest Africa, In western Asia, it has spread to the north of the Americas and east of Asia
