In the past two decades, a great deal of information on the role of endophytic microorganisms in nature has been collected. The capability of colonizing internal host tissues has made endophytes valuable for agriculture as a tool to improve crop performance. In this review, we addressed the major topics concerning the control of insects-pests by endophytic microorganisms. Several examples of insect control are described, notably those involving the interactions between fungi and grazing grasses from temperate countries. The mechanisms by which endophytic fungi control insect attacks are listed and include toxin production as well as the influence of these compounds on plant and livestock and how their production may be affected by genetic and environmental conditions. The importance of endophytic entomopathogenic fungi for insect control is also addressed. As the literature has shown, there is a lack of information on endophytes from tropical hosts, which are more severely affected by pests and diseases. Having this in mind, we have included an updated and extensive literature in this review, concerning new findings from tropical plants, including the characterization of endophytic fungi and bacteria microbiota from several Amazon trees, citrus and medicinal plants among others.

Merril) under different environmental conditions (2006, background): “Acremonium, a genus known to have effects on insects and other herbivores was also isolated (Breen, 1994; Azevedo et al., 2000), and Aspergillus, a genus containing species that could be used in insect control, although some species contain aflatoxins and other undesirable compounds.”
Diversity of fungal endophytes in shrubby medicinal plants of Malnad region, Western Ghats, Southern India (2008, background): “Colletotichum, Phomopsis, Phyllosticta, Pestalotiopsis, Cladosporium and Xylaria spp., which were isolated frequently in this study, have been reported as endophytes in a wide host range in the tropics (Azevedo et al. 2000; Suryanarayanan et al. 2002; Photita et al. 2005).”
