土壤因子对绿僵菌生命活动的影响研究进展

Edaphic Factor that Affect the Activity of Entomopathogenic Fungus Metarhizium anisopliae

绿僵菌是一种重要的昆虫病原真菌,它广泛分布于世界各地的土壤之中,在调节和控制土壤中有害昆虫方面发挥着重要作用。但在农业实际应用过程中,绿僵菌杀虫剂的施用效果很不稳定,原因之一是受到了土壤因子对其生命活动的影响。从土壤温度和水分、土壤pH、土壤微生物和土壤质地4个方面归纳总结了土壤因子对绿僵菌生命活动影响的研究进展,并对土壤因子影响绿僵菌生命活动的新研究方向进行了初步讨论,以期为进一步研究土壤因子影响绿僵菌生命活动的作用机理及绿僵菌在实际生物防控地下害虫领域的广泛和高效应用研究提供理论参考。

Metarhizium anisopliae is an important entomopathogenic fungus which is common and widely distributed in soil throughout the world. M. anisopliae plays an essential role in the regulation and control of soil pests and it is one of the most widely used biological insecticides. However, the efficiency of controlling soil pests is not steady, and one of the reasons is the activity of M. anisopliae affected by the complexity edaphic factors. The present article reviewed 5 edaphic factors that influence the activity of M. anisopliae, such as soil temperature and moisture, soil pH, edaphon and soil texture. New research direction about edaphic factor influencing on the activity of M. anisopliae was also discussed. The review would provide reference for further study of mechanism about the edaphic factors influencing life activities of M. anisopliae, which would be benefic to regulate and control soil pests using the M. anisopliae.
