Invasive insects can severely impact native ecosystems by disrupting food webs and causing declines in local biodiversity. They often outcompete native species for resources, such as food and habitat, leading to population declines or extinctions. Invasive species may introduce new diseases or alter the nutrient cycling processes within the ecosystem. These changes can have cascading effects on other organisms, creating an imbalance that affects ecosystem health and function. Preventing and managing invasive insect populations is crucial for preserving native biodiversity and maintaining ecological integrity.
