A mathematical simulation model to estimate population development in a honeybee colony after infestation with the mite Varroa jacobsoni

, : A mathematical simulation model to estimate population development in a honeybee colony after infestation with the mite Varroa jacobsoni. Zentralblatt fur Veterinarmedizin, B 27(9-10): 798-805

The populations of bees and of Varroa mites were studied using a simulation model with time-dependent parameters. A Fortran program was used to obtain numerical solutions to two differential equations and one integro-differential equation describing the numbers of bees and of mites. Actual data fitted the model well, and results are presented graphically.
