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.EnglishHoneybee colony loss; colony collapse; fractional calculus; Caputo derivative; Caputo-Fabrizio derivative; existence and uniquenessCOLLAPSEArticle
