Large scale production of New Zealand strains of <i>Beauveria </i>and <i>Metarhizium</i>

Abstract: Beauveria and Metarhizium spp. are currently under development around the world as biocontrol agents for a variety of pest insects. Use of these fungi in practical biocontrol programmes will require production of large amounts of inoculum. Although production techniques on solid substrates have been developed overseas, the production characteristics of New Zealand strains were unknown. The effects of solid media (rice, wheat and barley) with additives (glucose and yeast extract), temperature and length of incu… Show more

“…In an attempt to reduce costs and obtain large quantities of viable propagules, natural substrates, such as millet, corn kernels, wheat grain (Damir, 2006), tapioca flour, sweet potato, pumpkin and papaya extracts (Hepburn, 1985), mixtures of rice bran and husks, barley (Dorta et al, 1990;Nelson et al, 1996) and other substrates, have yielded promising results for the production of B. bassiana. However, these substrates were supplemented to ensure growth and sporulation of the fungus effectively.…”

“…Por otro lado se han probado sustratos naturales como arroz, bagazo de azúcar de caña, trigo, para la producción de hongos entomopatógenos con aditivos, Nelson et al (1996) obtuvieron hasta 4.38x10 9 con/g de arroz para B. bassiana, y hasta 1.42x10 9 con/gssi para M. anisopliae usando como aditivo glucosa y extracto de levadura. Garza-López et al (2011) obtuvieron una máxima producción de conidios de 1.14x10 9 con/gssi usando arroz precocido, con una cepa de Beauveria bassiana.…”

“…Son pocos los trabajos en los cuales se compara el nivel de conidiación y la calidad de los conidios obtenidos bajo sistemas superficial y sólido, por tanto en esta investigación se planteó cotejar la producción y la calidad de los conidios obtenidos en dichos sistemas y además bajo el efecto de pulsos de oxígeno (26% de O 2 ).Además en este trabajo se evaluaron dos parámetros de calidad de conidios, la viabilidad y la germinación. Las pruebas de calidad son un parámetro importante ya que algunos autores han mostrado que no necesariamente una elevada producción de conidios se relaciona con una gran calidad (Nelson et al, 1996).…”
