It belongs to Boletinellaceae family and is known as ＂black bolete＂. Its ecological habits and biotrophy are very complicated. It can be saprobic and successfully cultivated in mushroom house conditions. More often it grows closely with many plants, but is not mycorrhizal fungus. It forms a tripartite association with root mealy bugs and plants. The fungus produces special fungus-insect gall with the soil mealy bugs, which is a symbiotic association between these two creatures. The gall grows on plant roots with parasitic tendency. This paper is a compact report of the findings, including taxonomy, ecology, economic and cultivation of this mushroom.展开更多

It has been reported that honeybee colony collapse has increased dramatically for some time in different parts of the world. In order to investigate the causes of colony collapse, we establish a fractional multi-order honeybee colony population model. Two different models with Caputo and Caputo-Fabrizio differentiation operators have been compared. We justify the existence and uniqueness of the solution. Stability analysis has been presented. We find the numerical values of the fractional order （p, q） so that the numerical results are close to the experimental findings more than the integer-order case.展开更多
