“…La dosis letal media (DL50) y máxima (DL90) de B. bassiana sobre las larvas del III estadio de A. aegypti (Tabla 7) para cada uno de los tiempos establecidos evidencia que a mayor tiempo de exposición a las diferentes concentraciones de B. bassiana menor es la dosis letal media (DL50) y máxima (DL90), resultados similares a los de Daniel et al, (2017) quien reporta un (DL50) de 29,177 ppm a las 24 horas mientras que a las 48 horas determina una (DL90) de 1,2309 ppm. Se determinó las dosis letales medias (DL50) y dosis letales al 90% (DL90) a diferentes tiempos de exposición, las cuales fueron de 1,34E+10 y 1,29E+11 conidios/mL respectivamente y a las doce horas la (DL50) y (DL90) fueron de 1,31E+08 y 7,23E+08 conidios/mL, resultados que demuestran que las larvas de A. aegypti son susceptibles a la acción de los conidios, resultados similares con Alcalde et al, (2014) quien reporta una disminución de las dosis letales a mayor tiempo de exposición.…”

En el presente trabajo se evaluó la actividad larvicida de Bacillus thuringiensis H-14 var. israelensis y Beauveria bassiana sobre larvas del III estadio de Aedes aegypti, bajo condiciones de laboratorio, además se determinó la dosis letal media (DL50) y máxima (DL90). Se realizaron los bioensayos con doce grupos experimentales y dos grupos control, con tres repeticiones, utilizando 25 larvas del III estadio de A. aegypti en 100 mL de agua destilada por cada unidad experimental. Se utilizaron seis grupos experimentales con B. thuringiensis H-14 var. israelensis, a las concentraciones de 670; 1683; 4247; 10619; 26673; 67000 esp/mL y un grupo control; obteniéndose una mortalidad del 50% a las 8 horas y del 100% a las 24 horas. Con B. bassiana se utilizaron seis grupos experimentales a las concentraciones de 4x10 8 ; 1x10 9 ; 2,5x10 9 ; 6,3x10 9 ; 1,6x10 10 ; 4x10 10 conidios/mL y un grupo control; obteniéndose una mortalidad del 50% a los 7 días y del 100% a los 9 días. Mediante la dosis letal media (LD50) y máxima (DL90) se demostró que tanto B. thuringiensis H-14 var. israelensis como B. bassiana presentan mayor mortalidad en relación directa a la concentración e inversamente al tiempo. Se concluye que B. thuringiensis H-14 var. israelensis y B. bassiana a las diferentes concentraciones utilizadas en los bioensayos, presentó una alta actividad larvicida en A. aegypti bajo condiciones de laboratorio.

“…The insecticidal activity of beauvericin was first described by Hamil, Higgens, Boaz and Gorman () against a model organism Artemia salina Linnaeus (Anostraca: Artemiidae). Similarly, other authors assessed the insecticidal effect of the mycotoxin on many pests including but not limited to Schizaphis graminum Rondani (Hemiptera: Aphididae) (Ganassi, Moretti, Pagliai, Logrieco, & Sabatini, ) and Calliphora erythrocephala Meigen (Diptera: Calliphoridae) (Daniel et al, ); however, little is known about the effectiveness of beauvericin to control mite populations and no investigation about the activity of the mycotoxin against T. urticae was found in the literature . The objectives of the present study were to evaluate the efficacy of beauvericin for the control of T. urticae and to screen its application on greenhouse strawberries.…”

The entomopathogenic fungi Beauveria bassiana (Balsamo) Vuillemin is known to produce a broad range of secondary metabolites. Beauvericin, a cyclic hexadepsipeptide, is the best known mycotoxin produced by B. bassiana; however, reports discussing the insecticidal activity of beauvericin per se are limited. In this study, we assessed the lethal activity of beauvericin against Tetranychus urticae Koch (Acarina: Tetranychidae). In addition, screening for suitable application of the mycotoxin against T. urticae on greenhouse strawberries is discussed. Beauvericin was able to control successfully T. urticae where concentrations of 10, 100 and 1,000 µg/g recorded mortalities of 84%, 100% and 100%, respectively, against motile stages. Furthermore, beauvericin inhibited egg hatching up to 83.3%, 69.3% and 53.3%, respectively, using the same concentrations under laboratory conditions. Under greenhouse conditions, the efficacy recorded was 52.6%, 85.7%, 72.4% and 72.4% at 1, 3, 7 and 10 days post‐inoculation, respectively. Beauvericin was efficacious under greenhouse conditions since the application increased strawberry yields while showing no phytotoxicity and ecotoxicological risk. Resistance to beauvericin was not detected initially at the unselected strain of T. urticae. Yet, the laboratory selection of populations of T. urticae exposed to beauvericin resulted in relatively resistant T. urticae strain that displayed no cross‐resistance to cyflumetofen and bifenazate. The acaricidal activity of beauvericin documented in this study would increase the efficacy of integrated pest management strategies.

“…In 1969, the working group of Hamill et al, firstly discovered the insecticidal activity of BEA against a model organism Artina salina (Hamill et al, 1969 ). Similarly, other authors investigated the insecticidal effect of BEA on Aedes aegypti (Grove and Pople, 1980 ), Calliphora erythrocephala (Daniel et al, 2017 ), Spodoptera frugiperda (Fornelli et al, 2004 ), and Lygus spp. (Leland et al, 2005 ).…”

“…Although BEA has similar chemical structures with other cyclic hexadepsipeptide mycotoxins, this mycotoxin is more effective against A. aegypti and suggesting a unique mechanism of action exists (Grove and Pople, 1980 ). The methanolic and ethyl acetate-methanolic extracts of B. bassiana showed larvicidal activity against 3rd instar of A. aegypti (Daniel et al, 2017 ). Cyclodepsipeptides are the active principles for the larvicidal action.…”

Beauvericin (BEA) is an emerging Fusarium mycotoxin that contaminates food and feeds globally. BEA biosynthesis is rapidly catalyzed by BEA synthetase through a nonribosomal, thiol-templated mechanism. This mycotoxin has cytotoxicity and is capable of increasing oxidative stress to induce cell apoptosis. Recently, large evidence further shows that this mycotoxin has a variety of biological activities and is being considered a potential candidate for medicinal and pesticide research. It is noteworthy that BEA is a potential anticancer agent since it can increase the intracellular Ca2+ levels and induce the cancer cell death through oxidative stress and apoptosis. BEA has exhibited effective antibacterial activities against both pathogenic Gram-positive and Gram-negative bacteria. Importantly, BEA exhibits an effective capacity to inhibit the human immunodeficiency virus type-1 integrase. Moreover, BEA can simultaneously target drug resistance and morphogenesis which provides a promising strategy to combat life-threatening fungal infections. Thus, in this review, the synthesis and the biological activities of BEA, as well as, the underlying mechanisms, are fully analyzed. The risk assessment of BEA in food and feed are also discussed. We hope this review will help to further understand the biological activities of BEA and cast some new light on drug discovery.
