Mass production of entomopathogenic fungi Beauveriabassiana (Balsamo) by using agricultural products based on liquid- solid diphasic method for date palm pest control

ABSTRACT:In this study, fungi, the most appropriate medium for the production of Beauveria bassiana in liquid and solid phases to produce clamidospore and conidiosopre were elected. For the liquid phase of plant foods, including potatoes, wheat flour, rice flour, corn flour and sugar cane molasses, and for the solid phase of plant materials, including sugar cane, corn, barley, rice, millet and sorghum were evaluated. The performance characteristics of the liquid phase compared by spore concentration and germination percent of clamidospores. The performance characteristics of the solid phase compared by wet weight, dry weight, conidia concentration and germination. Results showed that between different plant extracts used as liquid and solid medium to produce clamidospores and conidia of B. bassiana were significantly different at and 1% probability. In the end sugar cane molasses extract and rice elected to produce clamidspore and conidia of B. bassiana respectively due to maximum produce and economic performance
