Ecological Interactions of Invasive Insects and Native Plant Species in Changing Climate

Abstract

Invasive insects pose a significant threat to native plant species and ecosystems, particularly in the context of changing climates. Understanding these interactions is crucial for effective conservation and management strategies aimed at mitigating the adverse effects of invasive species on native plant communities. Invasive insects often establish and proliferate in new habitats due to the absence of natural enemies and the availability of suitable resources. As climate change alters the distribution and phenology of plants, it can influence the susceptibility and resilience of native plant species to invasive insects. In some cases, rising temperatures and altered precipitation patterns may favour the spread and population growth of invasive insects, leading to increased herbivory, reduced plant fitness, and ultimately, altered community dynamics. Furthermore, changing climates can disrupt the synchrony between native plants and their pollinators or beneficial insect populations, further exacerbating the impacts of invasive insects. As native plants and pollinators respond differently to shifting climatic conditions, their interactions may become disrupted, potentially reducing the reproductive success and long-term survival of native plant populations. However, it is important to note that climate change can also create novel opportunities for both invasive insects and native plant species. In certain instances, invasive insects may benefit from warmer temperatures and expanded ranges, while some native plants may exhibit adaptive responses and resilience to changing climatic conditions. These complex interactions highlight the need for a comprehensive understanding of the ecological dynamics between invasive insects and native plant species under various climate scenarios. The ecological interactions between invasive insects and native plant species in changing climates have far-reaching consequences for biodiversity conservation and ecosystem functioning. As climates continue to evolve, it is imperative to further investigate these interactions and develop adaptive strategies to mitigate the impacts of invasive insects on native plant communities. By doing so, we can strive to preserve and restore ecological balance in the face of ongoing environmental change.
