Abstract Endophytes have been known to confer resistance to host plants against insect herbivores mediated by fungal alkaloids. In this study we have isolated an endophytic fungus Nigrospora sp. (Ascomycota: Sordariomycetes) from a native plant Tinospora cordifolia. To assess anti-insect potential, we tested to what extent the survival and development of Spodoptera litura (Lepidoptera: Noctuidae), a polyphagous pest, was affected when fed on artificial diet amended with different concentrations… 

Larvicidal and growth inhibitory effects of endophytic Aspergillus niger on a polyphagous pest, Spodoptera litura

Significant reduction in relative consumption and growth rates as well as efficiency of conversion of ingested and digested food under the influence of fungal metabolites indicate antifeedant and toxic effects of the fungus.

Insecticidal potential of an endophytic fungus, Cladosporium uredinicola, against Spodoptera litura

Evidence is provided that C. uredinicola isolated from T. cordifolia possesses anti-insect properties and may play an important role in protecting plants against insect pests.

Antifeedent and toxic activity of endophytic Alternaria alternata against tobacco caterpillar Spodoptera litura

The results indicate higher larval mortality on diet supplemented with the fungal extract than control and the antifeedant and toxic effects of A. alternata may be due to production of bioactive molecules by this fungus.

Enhanced Resistance to Spodoptera litura in Endophyte Infected Cauliflower Plants

It is concluded that antibiosis to S. litura could be imparted by artificial inoculation of endophytes and this could be used to develop alternative ecologically safe control strategies.

Schizophyllum commune induced genotoxic and cytotoxic effects in Spodoptera litura

This is the first report showing the insecticidal potential of S. litura and the genotoxic and cytotoxic effects associated with it, and the non toxic nature of extract.

An Alpha-Glucosidase Inhibitor from an Endophytic Cladosporium sp. with Potential as a Biocontrol Agent

The purified inhibitor was determined to be a phenolic compound with amine groups, demonstrating a noncompetitive type of inhibition in vitro, and a significant interaction between dextrose and malt extract, with first-order effect of pH.

Inoculation of cucumber plants with Beauveria bassiana enhances resistance to Aphis gossypii (Hemiptera: Aphididae) and increases aphid susceptibility to pirimicarb

The entomopathogen Beauveria bassiana (Bals.) Vuill. (Ascomycota: Hypocreales) can colonize plants endophytically and stimulate the production of secondary plant metabolites with anti-herbivore

Endophytic fungi as novel sources of biopesticides: the Macaronesian Laurel forest, a case study

The literature data available on insecicidal and nematicidal compounds identified from fungal endophytes are presented and a recent study on the endophytic biodiversity of a unique paleoflora, the Macaronesian laurel forest, is presented in the light of their role in plant protection.

Microbes as Biocontrol Agents

Use of microbes such as fungi, bacteria, yeast and viruses holds an enormous potential as biocontrol agents to replace conventional chemical-based pesticides and provide food security in a safe and eco-friendly manner.



Indirect effects of an unspecialized endophytic fungus on specialized plant – herbivorous insect interactions

The data suggest that unspecialized, soil-borne endophytic fungi, even when their association with the host plant is weak, can influence aboveground herbivore development and should be considered when investigating plant-insect interactions.

Fungal endophytes of Cyperus and their effect on an insect herbivore

Herbivory of infected and uninfected sedges was compared, suggesting that the endophyte may defend its host against herbivory in natural populations.

Effect of ergot alkaloids from fungal endophyte-infected grasses on fall armyworm (Spodoptera frugiperda)

The detrimental effects on fall armyworm observed in this study suggest that ergot alkaloids could be responsible, at least in part, for the greater insect resistance of endophyte-infected grasses.

Naturally-Occurring and Synthetic Loline Alkaloid Derivatives: Insect Feeding Behavior Modification and Toxicity2

Fall armyworm larvae were more susceptible, in terms of feeding behavior modification and reduced weight gain, to specific loline derivatives than European corn borer larvae.

Antifeedant and toxic activity of Trichilia americana extract against the larvae of Spodoptera litura

The biological activity of a crude methanolic extract of Trichilia americana (Sesse and Mocino) Pennington was assessed using the Asian armyworm, Spodoptera litura (Fabr.) to suggest both antifeedant and toxic activities.

Fungal loline alkaloids in grass–endophyte associations confer resistance to the rice leaf bug, Trigonotylus caelestialium

The results confirmed the ability of Neotyphodium‐infected forage grasses to control T. caelestialium propagation in meadows, which may cause damages to nearby rice paddies and indicated that the chemical has an adverse effect on survival of larvae, even at the lowest concentration tested, which was considerably lower than the typical concentrations in many NeotYphodium–grass associations.

Bioefficacy of crude extracts of Aglaia species (Meliaceae) and some active fractions against lepidopteran larvae

The isolation of the limonoid complex from A. elaeagnoidea should provide useful starting point for the development of a botanical anti‐insect preparation.

Isolation of feeding deterrents against argentine stem weevil from ryegrass infected with the endophyteAcremonium loliae

It is suggested that ryegrass staggers and stem weevil feeding deterrency may arise by different biochemical mechanisms.

The main constraint and continuing threat to cocoa production in Latin America is disease caused by two basidiomycete fungi belonging to the genus Crinipellis (Agaricales), both of which are
