Abstract (English): The use of entomopathogenic fungi is an ecological alternative which contributes to the protection of the enviroment and the ecosystem. This paper deals on some aspects of the taxonomy, identification methods, characterization, action ways, host range and the influence on enviromental factors in the biological effectiveness of Metarhizium genus. The characterization procedures includes the morphology of colonies, conidias, conidiophores and phialides, the profile of extracelular proteins, the determination of the physiological characteristics and the assessment of the pathogenic activity through the determination of mortality percentages according letal concentrations and times. The use of molecular techniques is essential in the phylogenetical studies. The importance of Metarhizium as biological control agent of different orders of insects and others arthropods is increasing in several countries and it is included in various pest management systems in Cuba.

Abstract (Spanish): La aplicación de hongos entomopatógenos es una alternativa ecológica que contribuye a la protección del medio ambiente y el ecosistema. Este trabajo tiene como objetivo abordar algunos aspectos sobre la taxonomía, los métodos de identificación, caracterización, modo de acción, el rango de hospedantes y la influencia de factores ambientales en la efectividad biológica del género Metarhizium. Las técnicas de caracterización incluyen la morfología de las colonias, conidios, conidióforos y fiálides, el perfil de proteínas extracelulares, la determinación de sus características fisiológicas y la evaluación de su actividad patogénica mediante la determinación de los porcentajes de mortalidad, en función de concentraciones y tiempos letales. El uso de las técnicas moleculares resulta esencial en los estudios filogenéticos. La importancia del género Metarhizium como agente de control biológico de diferentes órdenes de insectos y otros artrópodos, está incrementándose en numerosos países y se encuentra insertado dentro de varios sistemas de manejo de plagas en Cuba.
