SCREWWORM Meaning and
Definition
-
Screwworm refers to a type of parasitic fly belonging to the Calliphoridae family, particularly the species Cochliomyia hominivorax and Cochliomyia macellaria. These flies pose a significant threat to livestock animals, including mammals like cattle, sheep, horses, and even humans in rare cases. The name "screwworm" originates from the distinctive screw-like shape of the larvae's body.
The female screwworm fly lays its eggs in open wounds or body orifices of the host animal. Once the eggs hatch, the larvae begin feeding on the live tissue of the host, causing severe and potentially fatal infections. The larvae grow rapidly, burrowing deeper into the host's flesh as they mature. This parasitic infestation can lead to severe pain, tissue damage, secondary infections, and disruption of normal bodily functions.
Screwworm infestations, known as myiasis, require immediate attention and treatment to prevent further harm. Various control methods are employed to combat screwworm outbreaks, including insecticide application, trapping adult flies, and sterile insect techniques, which involves releasing sterile male screwworms to disrupt the breeding cycle.
Due to their capability to cause substantial economic losses in the agricultural industry and significant health concerns for humans and animals, screwworms are targeted for eradication programs in affected regions. Regular surveillance, prompt treatment, and preventive measures are vital to reducing the impact of this parasitic fly on both livestock and human populations.
Common Misspellings for SCREWWORM
Etymology of SCREWWORM
The word "screwworm" originates from the combination of two words: "screw" and "worm".
The term "screw" in the context of "screwworm" refers to the helical shape or twisting motion of the larvae of these insects. When the larvae burrow inside the host's flesh, they exhibit a spiraling or screw-like movement, hence the name.
The word "worm" is a generic term used to describe various types of legless invertebrate animals. In this case, it specifically refers to the larvae or maggots of the fly species known as Cochliomyia hominivorax, commonly called "screwworms".
The name "screwworm" is thought to have originated in the late 19th or early 20th century when people observed the characteristic twisting motion of these larvae, resembling the action of a screw.
