“…Diets amended with extracts containing loline derivatives reduced weight and altered certain behaviours of S. frugiperda and O. nubilalis, notably in the first insect (Riedell et al, 1991). Patterson et al (1992) observed in Lolium and Festuca that the production of alkaloids by Acremonium reduced attacks of the Japanese beetle Popilla japonica. Other works find that ambient variations may affect toxin production by endophytic fungi.…”

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.

“…A reduction in feeding by grass grubs in both field and laboratory experiments occurred when they were offered roots containing loline alkaloid concentrations !458 mg/g (Table 1 and 2). Patterson et al (1991) showed that Japanese beetle (Popillia japonica) grubs (Coleoptera: Scarabaeidae) were deterred from feeding when offered artificial diets containing NFL and NAL at 100 mg/g. However, feeding deterrence did not occur when the grass grubs were offered washed tall fescue roots with 93 mg/g NFL (Potter et al 1992).…”

“…Patterson et al (1991) showed that grubs of Japanese beetle (Popillia japonica; Coleoptera: Scarabaeidae) were deterred from feeding when offered artificial diets containing NFL and N-acetyl loline (NAL) at 100 mg/g dry weight. However, feeding deterrence did not occur when P. japonica grubs were offered washed tall fescue roots containing 93 mg/g NFL (Potter et al 1992).…”

Loline alkaloids produced by endophyte-infected meadow fescue were high (!1000 mg/g) in roots. The larvae of New Zealand grass grub are major subterranean pasture pests. In laboratory and field studies, grass grub larvae feeding on roots of endophyte-infected meadow fescue containing lolines at concentrations !450 mg/g either lost weight or gained less weight than the corresponding controls feeding on endophyte-free or low-loline meadow fescue. These results demonstrate that loline alkaloids in roots of meadow fescue have the potential to deter grass grub larvae from feeding and could contribute to control of this pest in a sustainable manner.

“…This endophyte-perennial ryegrass combination is also associated with the animal disease "ryegrass staggers" which is induced by the secondary metabolite lolitrem B (Di Menna, et al, 2012;Fletcher and Harvey, 1981;Gallagher, et al, 1982). The tall fescue endophyte, mainly used in the USA, expresses loline alkaloids (Schardl, et al, 2007), which provide potent insecticidal activity against a diverse array of insect pests (Jensen, et al, 2009;Patterson, et al, 1991;Popay and Lane, 2000;Reidell, et al, 1991;Wilkinson, et al, 2000;Yates, et al, 1989) as well as apparently conferring drought tolerance (Malinowski and Belesky, 2000). The major compounds in this structural class are N-M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT acetyl loline (NAL), N-formyl loline (NFL), and N-acetyl norloline (NANL) (Fig 1).…”
