摘要： Most ladybirds (Coccinellidae), notably predatory species, are vital natural enemies in agricultural ecosystems, though some phytophagous species may damage crops, playing a pivotal role in biological pest control and Integrated Pest Management (IPM). However, their populations are increasingly threatened by environmental stressors such as habitat loss, pesticide exposure, climate change, and invasive species. This review consolidates recent findings on how environmental stressors-such as climate change, habitat loss, and pesticides affect ladybird population dynamics, survival, and reproductive success, including the direct and indirect impacts of climate change (e.g., phenological mismatches and extreme weather events) and the physiological and behavioral effects of neonicotinoids and nano formulated pesticides. Furthermore, this review highlights conservation strategies to mitigate these threats, emphasizing sustainable agricultural practices, ecological corridors, and policy interventions. By integrating insights from multiple disciplines, this review underscores the urgency of adopting integrated conservation approaches to sustain ladybird populations and their role in biological control. Future research should prioritize long-term studies on multi-stressor interactions, microbial symbiont roles, along with their influence on host fitness, and region-specific conservation efforts to enhance ladybird resilience in changing environments.
