昆虫病原是许多昆虫和螨类的重要天敌，因此已被公认为提供重要的生态系统服务。事实上，真菌昆虫病原作为害虫的生防剂已被广泛研究，试图改善作物保护的可持续性。然而，尽管自19世纪初以来，我们对真菌昆虫病原生态学的了解大大增加，但我们仍然需要深入的生态学研究，以扩大我们的科学视野，促进这些生物被广泛采用为有效的生物防治剂。真菌昆虫病原与节肢动物、植物和其他微生物进化出了一些错综复杂的相互作用。这些关系的重要性和复杂性才刚刚显现出来。重要的是，将我们的思维从传统的生物防治转变为理解一个尚不为人所知的“深空”。分子技术和系统发育分析的使用帮助我们朝着这个方向前进，并为真菌之间的关系提供了重要的见解。然而，新的技术，如植物芯片和焦磷酸测序，可能会帮助我们超越熟悉的领域，进入可以帮助我们对真菌昆虫病原生态有一个新的理解的领域。
Entomopathogens are important natural enemies of many insect and mite species and as such have been recognised as providing an important ecosystem service. Indeed, fungal entomopathogens have been widely investigated as biological control agents of pest insects in attempts to improve the sustainability of crop protection. However, even though our understanding of the ecology of fungal entomopathogens has vastly increased since the early 1800s, we still require in-depth ecological research that can expand our scientific horizons in a manner that facilitates widespread adoption of these organisms as efficient biological control agents. Fungal entomopathogens have evolved some intricate interactions with arthropods, plants and other microorganisms. The full importance and complexity of these relationships is only just becoming apparent. It is important to shift our thinking from conventional biological control, to an understanding of an as yet unknown “deep space”. The use of molecular techniques and phylogenetic analyses have helped us move in this direction, and have provided important insights on fungal relationships. Nevertheless, new techniques such as the PhyloChip and pyrosequencing might help us see beyond the familiar fields, into areas that could help us forge a new understanding of the ecology of fungal entomopathogens.
