- Abstract
The production of entomopatógenous fungi for the control of insects pests, one comes developing in several countries existing several formulation techniques. In Cuba he/she stands out the handmade production of Beauveria bassiana it has more than enough solid substrate of leaders of rice fundamentally in magentas. At the moment this represents a problem for the limited accessibility of the components, as well as the economic aspect that rebounds in the commercialization and readiness of the product. The purpose of this work was to determine the sporulation of Beauveria bassiana in substrates in powders of rice, sorghum and corn in polypropylene bags, to a temperature of 30°C, using a chip support and saw dust. The sporulation was determined at 4 days of growth counting the spores in the camera of Neubauer, according to the method of French. The thermal integral was calculated for the 4 days of crop. The analysis of factorial variance determined that significant differences exist (P>0,05) in the production of spores in the solid substrates and the applied quantities. The substrates in powders of rice and corn presented the biggest concentrations on a saw dust support, to an applied quantity of 1,6 g of substrate powder, reaching holding of 3,4x1010 and 3x1010 respectively, it was selected as the best the powdered substrate of rice, to be the product dedicated to the production of this fungus. The thermal integral for the 4 days was of 100 °C. The productivity of the fungus increases significantly with regard to the traditional method of production (leaders of rice).
