摘要
冰草麦蚜Diuraphis(Holcaphis)agropyronophagaZhanssp.novined是在宁夏首次发现的一种为害小麦、赖草的新害虫。在室内变温条件下,测定该上发育起点为5.510±0.6℃.有效积温为19.5±8.5日度。以宁夏西吉县1996~1997年气象资料对测定结果进行了检验,其符合率为100%。
Diuraphis (Holeaphis) agropyronophaga Zhang is a new insect pest that damaged wheat and cerease wheatgrass in Ningxia. The temperature threshold of development, 5. 5±0. 6, and the effective accumulative temperature, 195±8. 5℃ day-degree, were measured with natural temperature in the laboratory. The results, a hundred percent of conformity of the occurence date in the measuring experiment with that of each generation in acturallity, were tasted with the climatic data from 1996 to 1997.
