| Abstract: | Major alfalfa insects were systematically investigated in three survey sites where can represent three main biological areas of Ningxia. Acording to the investigation results, the law of field growth and decline of alfalfa aphids, thrips, grass moth, bugs and leaf miner in different biological areas of Ningxia was preliminarily analysed. It was clear about population change, the Severe occurrence period and harmfulness of alfalfa major insects in Ningxia. It will make an important basis for forecast and control of alfalfa insects. |
