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. The natural and biological control of pests and diseases affecting cultivated plants has gained much attention in the past decades as a way of reducing the use of chemical products in agriculture. Biological control has been frequently used in Brazil, supported by the development of basic and applied research on this field not only in our country but also in South America as it can be found in several reviews (Lecuona, 1996;Alves, 1998;Melo and Azevedo, 1998). In fact, by having vast agriculturable areas and most of its territory in the tropical region, Brazil and all Latin America, show their agriculture severely affected by agricultural pests. The use of agrochemicals, although decreasing the attack of insects and phytopathogenic microorganisms, still represents a high risk to field workers and consumers. In addition, their use is, in certain cases, economically unviable. The control of pests and diseases by means of biological processes i. e., use of entomopathogenic microorganisms or those that inhibit/antagonise other microorganisms pathogenic to plants, is an alternative that may contribute to reduce or eliminate the use of chemical products in agriculture.

“…Surveys of old perennial rye-grass pastures indicate that the infection level increases with age (Funk, Saha & Johnson-Cicalese 1984;Lewis & Clements 1986). Old pastures typically show higher levels of endophyte-infection in other grasses as well (Diehl 1950;Latch, Potter & Tyler 1987).…”

“…Several projects in Europe have surveyed old pastures of perennial ryegrass, regarded as natural, for presence of endophyte (Lewis and Clements 1986;Latch et al 1987;Lewis et al 1997;Oliveira and Castro 1998). Such surveys usually find that the frequency of endophyte infection in populations is quite modest, and that infected populations do not appear to be significantly fitter than uninfected populations.…”

Neotyphodium endophytes profoundly affect the biology of their host grasses, including the important forage species perennial ryegrass, tall fescue and meadow fescue. The endophytic association is finely balanced, involving adaptation in each associate. The evidence for co-adaptation is discussed. The presence of endophyte, and the difference between endophyte strains, can affect some plant properties more than genetic variation intrinsic to the host. Conversely, host genotype exerts significant influence on the activity of the endophyte. Control of endophyte status is essential in any grass breeding programme, and developing knowledge of endophyte and its role in a herbage association offers new opportunities to grass breeders.
