“…3 Beauvericin was first described from an entomopathogenic fungus Beauveria bassiana on the basis of its toxicity to brine shrimp. 4 In addition to a number of reports from this species and other Beauveria species, this compound has also been isolated from several other entomopathogenic fungi such as Isaria tenuipes (formerly Paecilomyces tenuipes, also known as Isaria japonica), [5][6] Isaria fumosorosea (formerly Paecilomyces fumosoroseus), 7 and Cordyceps cicadae. 8 All these species belong to the family Cordycipitaceae in the Hypocreales (Ascomycota).…”

Beauvericin was analyzed in three forms of the Lepidoptra pathogenic fungus Isaria tenuipes (4 isolates): (a) natural specimen, (b) cultivated synnemata on rice media, and (c) mycelia from fermentation in liquid media. Beauvericin was detected in very low amounts in all tested natural specimens. Synnemata on rice contained much higher concentrations of beauvericin than the corresponding natural materials, although the concentrations were lower than mycelia from liquid fermentation. The results casted a caution that beauvericin concentration should be carefully checked, as a possible toxic constituent, upon mass production of a selected strain of Isaria tenuipes for health food purposes.

“…In contrast, Champlin and Grula (1979) reported that beauvericin was not toxic to Helicoverpa zea Boddie and that bassianolide caused temporary atony. Paecilomyces fumosoroseus (Wize) Brown & Smith (=Isaria fumosorosea) has also been reported to produce beauvericin (Bernardini et al, 1975) and beauverolides (Jegorov et al, 1994), and Verticillium lecanii (=Lecanicillium lecanii) also produces bassionalide (Suzuki et al, 1977). Other entomopathogenic fungi also produce metabolites, e.g., Isaria spp.…”

Fungal endophytes are quite common in nature and some of them have been shown to have adverse effects against insects, nematodes, and plant pathogens.Our research program is aimed at using fungal endophytes-mediated plant defense as a novel biological control mechanism against the coffee berry borer, the most devastating pest of coffee throughout the world. A survey of fungal endophytes in coffee plants from Hawaii, Colombia, Mexico, and Puerto Rico has revealed the presence of various genera of fungal entomopathogens, including Acremonium, Beauveria, Cladosporium, Clonostachys, and Paecilomyces. Two of these, B. bassiana and Clonostachys rosea, were tested against the coffee berry borer and were shown to be pathogenic. This paper reviews the possible mode of action of entomopathogenic fungal endophytes. Published by Elsevier Inc.

“…BEA, although first isolated in 1969 [135] from Beauveria bassiana and later from Paecilomyces fumoso-roseus [136], was only isolated from Fusariurn species (E moniliforme and E semitectum) in 1991 [ 130]. Since then, several other Fusarium species commonly associated with growing crops have been reported to produce BEA (E pro liferatum [135]; E subglutinans [128,129,137].…”

The phytotoxicity ofFusarium metabolites: An update since 1989

The present article summarises the published phytotoxic effects of severalFusarium metabolites (mycotoxins, phytotoxins, antibiotics and pigments) since 1989. The phytotoxicity of many of the commonly isolated metabolites cannot be disputed, but their role in pathogenesis ofFusarium-induced plant diseases is uncertain. Plant species/varieties differ in their susceptibililty resistance to these toxinsin vitro, as well as toFusarium pathogens under field conditions. Such variations in plant response may reflect resistance mechanisms that operate at several levels, including an initial ability to prevent fungal invasion; prevention of fungal spread and toxin tolerance or degradation. Little is known about the mode of action of most of these metabolites on either animal or plant cells. Several novelFusarium metabolites have been isolated in the past few years. Many are toxic to animals and cell lines, but assessment of their phytotoxicity has largely been neglected. Since many plant pathogenic Fusaria produce a plethora of metabolites, the additive or synergistic actions of toxins in combination must be considered in plant pathology.
