“…It was discovered that the mortality and egg hatching rates in the Czapek medium were similar to those observed in the distilled water. Our results corroborated Sharapova [ 43 ] and Wu et al [ 44 ], who reported that the medium exhibited no nematicidal ability. Our findings also showed that all fermentation concentrations had a nematicidal impact on M. enterolobii .…”

Meloidogyne enterolobii is one of the most virulent root-knot nematodes (RKNs). Aspergillus tubingensis Raoul Mosseray, 1934, is used to produce bioactive substances, enzymes, and secondary metabolites. However, no research has been conducted yet on the efficacy of A. tubingensis against plant-parasitic nematodes. Thus, the novel research was planned to evaluate the biocontrol efficacy of A. tubingensis fermentation against M. enterolobii. The findings showed that egg hatching inhibition and mortality of M. enterolobii increased with increasing concentration of fermentation and exposure time. The maximum second-stage juveniles (J2s) mortality was achieved via 100% fermentation at 72 h. Similarly, 100% fermentation inhibited 99.9% of egg hatching at 8 d. A. tubingensis fermentation increased plant biomass, decreased second-stage juvenile invasion, and inhibited nematode development and reproduction in greenhouse conditions. A. tubingensis reduced J2 invasion into tomato roots by 42.84% with CS+ (coated seeds plants with nematodes inoculum) and 27.04% with T+ (100% fermentation broth and nematodes inoculum both) treatments. Moreover, CS+ and T+ treatments decreased nematode development by 54.31% and 21.48%, respectively. It is concluded that the A. tubingensis GX3 strain can be used as a novel microbial biocontrol agent against M. enterolobii.

“…And phytopathogenic fungus Ganoderma applantum has also been used under laboratory conditions for the control of larvae of these same insects, reporting a mortality of 50% after 24 hours of application, observing damage in the epithelial cells of the midgut and damage to muscle tissues in insects [9]. Another method commonly applied for the control of some biopesticides is the use of organic biopreparations such as whey and grain liquor, complemented with B. bassiana extract for adults of adults Drosophila melanogaster (Fallén, 1823) intensifying its effectiveness, being able to observe 100% mortality two days after application [61]. It can be observed that the synergistic use of these organic biopreparations with the extract of this fungus has a faster effect for the control of this pest.…”

The use of entomopathogenic fungi (EF) in recent years has been highly effective against the different orders of insects considered pests of agricultural importance and their conidia have been commonly applied, but it has been reported that these are sensitive to the environmental conditions. For this reason, biopesticides products have been formulated based on secondary metabolites, recently. These biomolecules participate as biological control agent, such as: cyclic depsipeptides, amino acids, polyketides, polyphenols and terpenoids, affecting their morphology, life cycle and insect behavior. The use of secondary metabolites of entomopathogenic fungi opens the possibility of application in a more efficient way for the control of agricultural pests in a compatible with the environment and human health; therefore, it is important to know, analyzing the type of molecules, their effects, and their different methods of application.

“…De estos, los más comunes son PDA, Agar Agua (AA), Sabouraud Dextrosa Agar (SDA), Sabouraud Dextrosa Agar con extracto de levadura (SDAY) y Agar Melaza levadura (AML). Al respecto, se han llevado a cabo estudios para determinar el crecimiento radial de los hongos M. robertsii y B. bassiana bajo diferentes condiciones de crecimiento (García-Gutiérrez et al 2020), y otros con la finalidad de inducir su patogenicidad al usar suplementos de integumento de algunos insectos diana (González García et al 2001;Sharapova 2019;Sapna Bai et al 2020), así como para conocer su potencial en la inducción de la actividad enzimática dinámica y caracterización bioquímica de B. bassiana (Peteira et al 2011). Los hongos tienen diferentes atributos que determinan su virulencia frente a sus hospedantes, tales como la producción de enzimas hidrolíticas como proteasas, lipasas y quitinasas (Zibaee & Bandani, 2009;Batool et al 2020).…”

El uso de cutícula de insectos es una opción viable para inducir el crecimiento de hongos entomopatógenos. Se obtuvo polvo de pupas de Spodoptera frugiperda (Sf) y Heliothis virescens (Hv), el cual se adicionó para enriquecer al medio de cultivo Papa Dextrosa Agar (PDA) a concentraciones de 0,25, 0,5 y 1 %. El polvo se usó para inducir crecimiento radial de Beauveria bassiana y Metarhizium robertsii. Se determinó el tiempo letal (TL) de M. robertsii inducido a una concentración de 108 esporas/mL y un control PDA. La mortalidad de larvas fue analizada mediante ANDEVA y una prueba Tukey (α = 0,05). El contenido de grasa de Sf fué 49,9 y el de Hv 41,9 %; el extracto libre de nitrógeno (ELN) 21,3 y 32,0 %; proteínas 15,7 y 13,5 %, y la energía 517,87 y 493,73(Kcal/g), respectivamente. Los nutrientes y la energía tuvieron efecto inductor en el crecimiento de M. robertsii con polvo de pupa de Sf y Hv al 1%, alcanzando 75,5 y 74,2 mm de crecimiento radial y en el control PDA 60 mm. B. bassiana con Hv 0,5 %, 55 mm y con Sf 0,25 %, 50 mm y en el control PDA 32,5 mm (α=0,05). M. robertsii inducido con Sf causó 91,6 % de mortalidad de larvas de Sf y en PDA 66,6 %, a los siete días (α = 0,05). El suplemento de insectos incrementó el crecimiento de hongos en medio PDA, esto contribuyó a la patogenicidad de la cepa inducida de M. robertsii sobre S. frugiperda.
