The dynamics of the total number of fruit flies in the 4 quadrants of the domain (each line represents one quadrant) during 10 generations, when no chemical information is present (control), only food odors are present (F) or both food odors and aggregation pheromones are present (F + A), for the resource densities of 1 apple m−2 (a–c) and 10 apples m−2 (d–f). The apples were randomly distributed per resource block. The initial fruit fly population P 0 = 2,000 was situated in one cell in the center of the domain. The attraction towards infochemicals was κ = 5 and η = 2.51.
