INTRODUCTION.

The common green bottle fly is a blowfly found in most

areas of the world and is the most well-known of the numerous green bottle fly species. Its body is 10–14 millimeters in length – slightly larger than a house fly – and has brilliant, metallic, blue-green or golden coloration with black markings.

MORPHOLOGY.

Adults: The adults are usually a metallic green and can also have

a copper green color. The mouthparts are usually yellow (Apperson et al. 2011). The back is hairy and the overall diameter is about 8–10 mm. The squamae at the base of the wings are hairless

Eggs: The eggs of L. sericata are usually white, but can be a pale

yellow. They are often deposited in batches or masses. The eggs are elongated with one end tapered slightly, and are approximately 1.5 mm long

Pupae: The pupae are enclosed in a hardened shell that is usually

reddish brown, light brown or black in color. This shell is comprised of the last larval instar skin. They are 9–10 mm long with a width ranging from 3 to 4 mm

LIFE CYCLE.

The Life cycle of Lucilia sericata consists of four stages that include adult, egg,

larva, and pupa. Each female can lay 2000-3000 eggs in 9-10 batches within only 3 weeks! ... Maggots then hatch from the eggs and attach themselves to an organism that it is on. After about 4-9 days the maggots are done with development.
Maggots then hatch from the eggs and attach themselves to an organism that it is on. After about 4-9 days the maggots are done with development.
The maggots will then go into a pre-pupa stage where they will burrow themselves into soil and then pupate into a pupa.
In this stage, the maggot is encompassed in a hardened shell where it will molt and gain wings. They are motionless, do not eat, and cannot protect themselves. An average pupa stage will last about 7 days. Some flies can stay in the pupa stage for up to 115 days because of low soil temperatures.

Adult flies will then escape from their pupa and journey above

the surface of the soil
At first the fly will be soft and not contain its bright green color. It will take the body of the fly 48 hours to harden, which it will then display, color and finally have fully functional wings. Mating activity will then occur anywhere from 3-8 days after emergence. Then the life cycle will start all over again!

Disease caused by them…..

Semi-specific myiasis:
also called facultative/opportunistic. They are not

normally parasitic, but will do so if the opportunity arises, particularly if facilitated by wounds/sores already present. They can, however, develop without the host
These also include species that normally lay eggs in animal or vegetable matter (transmission that ingesting contaminated food)
The most notable of the semispecific is probably the green-bottle fly, Lucilia

TREATMENT:-

Applies once an infestation is established. In many circles the first

response to cutaneous myiasis once the breathing hole has formed, is to cover the air hole thickly with petroleum jelly. 
Lack of oxygen then forces the larva to the surface, where it can more easily be dealt with.
 A clinical or veterinary setting there may not be time for such tentative approaches, and the treatment of choice might be more direct, with or without an incision.
First the larva must be eliminated through pressure around the lesion and the use of forceps. Secondly the wound must be cleaned and disinfected. Further control is necessary to avoid further reinfestation.

Symptoms….

myiasis affects the human body depends on where the larvae are

located.
Larvae may infect dead, necrotic (prematurely dying) or living tissue in various sites: the skin, eyes, ears, stomach and intestinal tract, or in genitourinary sites.
They may invade open wounds and lesions or unbroken skin. Some enter the body through the nose or ears. 
Larvae or eggs can reach the stomach or intestines if they are swallowed with food and cause gastric or intestinal myiasis
Crawling sensations and buzzing noises. Smelly discharge is sometimes present. If located in the middle ear, larvae may get to the brain.

PREVENTION AND CONTROL:-

The first control method is preventive and aims to

eradicate the adult flies before they can cause any damage and is called vector control. The second control method is the treatment once the infestation is present, and concerns the infected animals (including humans).
One prevention method involves removing the environment most favorable to the flies, such as by removal of the tail. Another example is the crutching of sheep, which involves the removal of wool from around the tail and between the rear legs, which is a favorable environment for the larvae.

To prevent myiasis in humans, there is a need for
general

improvement of sanitation,
personal hygiene,
and extermination of the flies by insecticides.
Clothes should be washed thoroughly, preferably in hot water, dried away from flies, and ironed thoroughly.
The heat of the iron kills the eggs of myiasis-causing flies
