 Horses and Other Equines

TICKS

 The tropical horse tick is a
serious problem because it transmits
piraplasmosis. All stages can be
found in the ears of the host. The
female drops to the ground to lay eggs.
When the larvae hatch, they reinfest
the horse's ears. The life cycle is
45-60 days under ideal condtions.

 Dilute dusts and/or oil-based
insecticide solutions applied to the
ear give satisfactory results. All
other equine ticks are similar to
cattle ticks.

 Poultry

LICE

 Only biting lice infest poultry.
They spend their entire life cycle on
the host. The life cycle takes 4-7
weeks. Louse transmission is by
direct contact with infested animals.

 Infested birds become restless
and damage themselves by pecking at
body areas. Weight gain and egg
production may decrease. Treatment
consists of application of dusts or
sprays onto the bird or providing
self-treatment devices such as
dust boxes.

MITES

 Several species of mites infest
poultry. The chicken mite feeds on
blood at night whereas the fowl mites
are found on the birds at all times.


 Infested birds become irritated
and anemic. If not controlled dense
mite populations may reduce weight
gains and egg laying or cause death.
The life cycle takes 10-21 days. Mitp
infestations are transferred from bird
to bird, and sometimes as the result
of an invasion from wild birds. Other
means are in infested feathers and
poultry handling equipment, flats,
manure, workers, and poultry feet.

 Mites are controlled with acaricide
sprays or dusts directly on the
birds or in self-treatment devices.
Mites which infest only the legs of
poultry can be controlled by dipping
the bird in insecticide solutions.

FLEAS

 The sticktight fleas may
occasionally become a pest on poultry.
More serious infestations occur on
chicks than on mature birds. Under
extreme conditions, flea infestations
can cause death of chicks and poults.
The adult fleas usually are attached
to the bird around the head. The
immature stages are found in the
litter.

 Flea control is best achieved
by spraying infested birds and the
premises. The sticktight flea is
not a problem under good sanitation
conditions.

FLIES

 Many types of domestic flies
are pests on poultry farms. These
include the common house fly and
the drone fly. All these develop
in poultry droppings. Various blow-
fly larvae develop in carcasses of
dead birds and possibly in droppings.
