J. Watmough et al., DISTINGUISHING THE EFFECTS OF DILUTION AND RESTRICTED MOVEMENT ON THEINTRA-NEST TRANSMISSION OF HONEYBEE QUEEN PHEROMONES, Bulletin of mathematical biology, 60(2), 1998, pp. 307-327
This paper develops a simple model for the movement of a non-volatile
pheromone through a honey-bee hive. The model is specifically develope
d for a pheromone produced by the queen which is thought to regulate c
olony swarming. Although the model begins as a system of partial integ
ro-differential equations, it is in the end reduced to a system of lin
ear, first-order partial differential equations for the average pherom
one level per worker, che pheromone level of the hive substrate, and t
he pheromone level of the queen. Analysis of this system shows that bo
th colony size and hive area have independent effects on the average p
heromone levels of the workers, hut that worker congestion can have an
even stronger effect on the pheromone distribution. These results est
ablish a relationship between colony size, hive area, worker crowding,
and queen-pheromone transmission. (C) 1998 Society for Mathematical B
