Sticky cards are brightly colored adhesive traps (commonly yellow and blue) used to monitor and reduce populations of flying insect pests such as whiteflies, aphids, thrips, leaf miners, and fungus gnats. They work by visually attracting pests with their color and trapping them on the sticky surface. Their importance lies in offering farmers an eco-friendly, chemical-free tool for early pest detection, population monitoring, and mass trapping-helping reduce pesticide sprays, delay resistance development, and protect beneficial insects.
