common housefly is a prime disease carrier and can travel up
to 5 miles in one day in search of food. Common house flies
are strongly attracted to UVA and green light except during
the first few days after emerging from pupation. Food lures
and sex pheromone traps are also strong attractants.
to the common housefly, lesser house flies have more slender
bodies and a more hovering and jerky pattern of flight. Although
less common, this species is not strongly attracted to UVA light
so other methods of control should be used.
species is attracted to fermenting fruit and is a particular
nuisance to the brewing industry. UVA and green light are attractants
for flies except those less than 4 days old, so other defences
will be required.
variations in behaviour among flies
Male flies migrate and are strongly attracted to pheromones.
Older flies have a preference for looking for landing sites
in order to mate. Hungry or unfed flies, however, will be more
attracted to food. Responsiveness to light will also also vary
between species and at certain times of the day.
