What Causes Flystrike In Sheep?

What Causes Flystrike In Sheep?

Lucilia cuprina, commonly known as the Australian sheep blowfly is the major species causing problems for Victorian sheep producers.

How does flystrike affect sheep? Blowfly strike (flystrike) occurs when the eggs of the sheep blowfly (Lucilia cuprina) hatch in moist wool and the maggots feed on the flesh of the live animal. The maggots create painful wounds which, if undetected, can debilitate the animal to the extent that it eventually dies of blood poisoning.

Which fly causes fly strike in sheep? In the UK, blowfly strike is usually caused by the greenbottle fly. The females are attracted by the odour of decomposing matter such as wounds, soiled fleece or dead animals. Each female lays up to 250 eggs that hatch after about 12 hours. After three days the mature larvae drop off the sheep and pupate in the soil.

What does flystrike look like in sheep? Early signs of flystrike can be very difficult to observe. Sheep may appear restless, nibble at areas of the body, exhibit shade-seeking behaviour or stamp their feet. Sometimes affected sheep will not show any signs until a significant amount of maggots are present and have caused the animal to feel uncomfortable.
