Flies will often lay eggs on spoiled meat because they are attracted to the smell of the meat. The meat will provide a place for the eggs to incubate and also a source of food once the larvae hatch.
Adult flies do this so that their babies(maggots), will have a food supply when they are born. Adult flies will lay eggs on meat, waste, or anything else for their young to eat on.
Flies lay eggs in spoiled meat because it is moist. Also once the eggs hatch it provides the maggots with plenty of food to eat.
Yes, it means spoiled and covered with eggs and larvae of flies; "flyblown meat"
The fly eggs hatch into larvae (also known as maggots) that feed on the protein and eventually pupate (cocoon) to become adult flies.
Flies are attracted to meat and will lay eggs on the meat, where they quickly hatch into maggots. But the flies are not indigenous to the meat.
Yes, if flies lay eggs in exposed rotting meat their larva will feed themselves until developed and then turn into new flies. If the rotting meat is not exposed the flies will not be able to lay eggs and there will be no emerging flies.
Rotting meat doesn't create flies. Rotting meat attracts flies that lay their eggs on the meat. These eggs hatch and maggots emerge and proceed to feed off the rotten meat. After a period as a chrysalis, the maggots change and emerge as adult flies.
Pasteur
It only takes a few hours for maggots to appear on rotting meat. The fly lays its eggs on the meat and maggots are born within a few hours.
Salmonella
Maggots are the larvae of regular flies which lay there eggs in old food/meat/faeces. These eggs hatch into maggots which eventually become flies. So it goes, eggs ---> maggots ---> flies
Redi used a jar, meat and gauze. The gauze kept the flies off the meat. Redi's hypothesis was that if you kept flies away from the meat, maggots would not appear, because the flies did not lay eggs on the meat.
Redi reasoned that flies had laid eggs on the meat in the open jar. The eggs hatched into maggots. Because flies could not lay eggs on the meat in the covered jar, there were no maggots there. Therefore, redi concluded that the decaying meat did not produce maggots.
