“…Para la multiplicación de conidias, se inoculó arroz precocido estéril en bolsas de polipropileno con un trozo de la colonia de Qu-M270 (Cherry et al, 1999). La cosecha de conidias se realizó mediante un tamizado con apertura de 100 µm, luego se deshidrataron y almacenaron al vacío (Rodríguez et al, 2004) hasta su utilización en el estudio.…”

“…consisting mostly of single conidia with mycopesticides) that would usually be monitored with a PSA (Cherry et al, 1999). Use of such instruments is therefore practical and a good method of not only determining hydrophobicity of the conidia but also of examining how conidia interact within a particular liquid.…”

“…Of these, sample DM2 was produced in a laboratory and samples ME 006 and ME 008 were produced by a commercial company. Beauveria bassiana and the Trichoderma species were mass-produced by a two-stage process based on the method used by Cherry, Jenkins, Heviefo, Bateman and Lomer (1999). The first stage was a liquid culture followed by conidiation on a sterile solid substrate, Basmati (Tilda) rice.…”

Fungal formulations are vital for effective biopesticide development. Good formulations help to optimise field efficacy while poor formulations result in product failure. This study aimed to produce a hydrophobicity test that would be appropriate for fungal conidia produced to a commercial quality and determine relative hydrophobicity of fungi from four different genera by using laser diffraction. A eichhorniae the most hydrophobic conidia. Particle size analysis was a more accurate test for comparing fungi from difference genera compared to the SAS test and phase exclusion assay. PSA was also used to test three emulsions and demonstrated that different formulations had an effect on particle size.

“…It has been suggested that on-site or cottage-industry biopesticide production may be one approach to overcoming these constraints [1]. In developing countries with lower labor costs, small-scale, solid fermentation methods are frequently used for the production of certain fungal bioinsecticides [3,6,2]. Even with low wage rates, it has been reported that labor accounts for 30% of the cost of bioinsecticide production using solid-substrate fermentation methods [3].…”

Even with low wage rates, it has been reported that labor accounts for 30% of the cost of bioinsecticide production using solid-substrate fermentation methods [3]. On-site, small-scale production of bioinsecticides using deep-tank fermentation technology may help lower production costs due to reduced manpower requirements for fermentor operation and product handling.…”

The production of fungal spores using on-site, non-sterile, portable fermentation equipment is technically constrained. Very little information is available on the production requirements, such as medium concentration, inoculum stabilization, required fermentation times, and maintenance of axenic growth. In this study, we developed a two-part, liquid concentrate of the production medium that remains stable and soluble at room temperature. We also examined inoculum stability and showed that freeze- or air-dried blastospore preparations were stable for 7 days after rehydration when stored at 4 degrees C. The use of a low-pH (pH 4), relatively rich complex medium provided a growth environment deleterious to bacterial growth yet conducive to rapid sporulation by Paecilomyces fumosoroseus. High concentrations of blastospores (7.9 x 10(8)/ml) of P. fumosoroseus were produced in a 40-h fermentation with very low levels of bacterial contamination when the fermentor was charged with a blastospore production medium with a starting pH of 4 and inoculated with blastospore concentrations greater than 1 x 10(6) spores/ml. These studies demonstrate that the use of disinfected, portable fermentation equipment has potential for on-site production of high concentrations of blastospores of the bioinsecticidal fungus P. fumosoroseus.
