宁夏荒漠草原主要害虫定殖风险分析

Establishment Probability Analysis of Important Insect Pests in Ningxia Desert Steppe

本文通过在田间调查和室内鉴定的基础上,利用定殖风险分析软件SOM对82种害虫在27种荒漠草原组的定殖风险进行了分析研究,并进行了排序。结果表明:一些害虫虽在荒漠草原某一组上未发生,但其有较高的定殖概率;各个害虫在每一荒漠草原组的定殖概率虽有不同,但所有荒漠草原组排在前10的有一定的相似性。

Based on field investigation and laboratory identification, the establishment risk analysis software SOM was applied to carry out studies for 82 kinds of pests in 27 types of desert steppes. The obtained establishment probabilities were ranked. The results showed that some pests didn't occur in a certain group of desert steppe, but they had high establishment risk. Although the establishment probabilities are different for each species in each desert steppe group, they are similar for top ten species in all desert steppe groups.
