fruitvlieg

Fruitvlieg refers to several small flies in the family Drosophilidae, most commonly the genus Drosophila. They are attracted to fermenting fruit and other decaying organic matter and can appear in homes, farms, and markets. The best-known species is Drosophila melanogaster, a staple in genetics research.

Most fruitflies are about 2 to 4 millimeters long. Adults have slender bodies, clear wings, and often red eyes in many laboratory strains. The life cycle proceeds quickly: eggs are laid on or near fermenting material; larvae feed on yeast and microorganisms; after several molts they pupate and emerge as adults. At room temperature, the cycle from egg to adult can be about 7 to 10 days, allowing rapid population growth in suitable environments.

Ecologically, fruitflies are detritivores, helping to break down ripe fruit and other organic matter. They also serve as food for predatory insects and other animals. In science, Drosophila melanogaster is one of the most studied model organisms in genetics and developmental biology; its genome has been extensively mapped and manipulated, yielding many research tools.

Distribution is worldwide, especially in regions with abundant fruit and vegetables. They are generally considered minor agricultural pests and household nuisances rather than dangerous disease vectors. Management focuses on sanitation (removing overripe fruit), proper storage, and trapping with vinegar- or wine-based baits; in some settings, biological controls or targeted insecticides may be used, with caution.
