Ripsieläimiin

Ripsieläimiin, known scientifically as Thysanoptera, are a small order of insects commonly called thrips. They are characterized by their slender bodies and fringed wings, though some species are wingless. Their size typically ranges from 0.5 to 5 millimeters, making them difficult to see with the naked eye. Thrips exhibit incomplete metamorphosis, with egg, larval, pupal, and adult stages. The larvae are generally worm-like and lack wings, while the pupal stage may occur in the soil or on plant surfaces.

These insects feed by piercing plant tissues with their asymmetrical mouthparts and sucking out the cell contents. This feeding behavior can cause significant damage to a wide variety of crops and ornamental plants, leading to distorted growth, discolored patches, and reduced yields. Some species of thrips are also vectors for plant viruses, further exacerbating crop losses. While many thrips are herbivorous, a few species are predatory, feeding on other small arthropods, including other thrips or mites, and play a role in biological control.

Thrips are found worldwide, inhabiting diverse environments from tropical rainforests to temperate grasslands. They are often associated with plants, residing in flowers, leaves, and bark. Their small size and cryptic habits can make them challenging to control. Integrated pest management strategies, including the use of insecticides, biological control agents, and cultural practices, are often employed to manage thrips populations in agricultural and horticultural settings.
