Research Objective

To provide comprehensive information on the possible entry routes of Solenopsis invicta invasions and to offer guidelines for the implementation of Integrated Pest Management (IPM) strategies against it.

Methodology

This study is a comprehensive review and synthesis of existing literature on the red imported fire ant (RIFA), Solenopsis invicta. It draws upon various research findings, historical data, and observations related to the biology, invasion history, economic impacts, and control strategies of RIFA.

Discussion

The paper discusses the origin and biology of Solenopsis invicta, detailing its colony structures (monogyne and polygyne), reproduction, and life cycle. It extensively covers the historical background of RIFA invasions in various countries, including Australia, China, Taiwan, India, Japan, and South Korea, highlighting the economic costs and eradication efforts. The discussion also delves into the threats posed by RIFA to public health, agriculture, urban settings, and biodiversity, emphasizing its role as an effective competitor and disruptor of ecosystems. The influence of environmental factors, especially temperature, on RIFA's foraging and adaptation is analyzed. Finally, it explores various integrated management strategies, including preventive measures, non-chemical controls (cultural practices, botanicals, microbial control, entomopathogenic nematodes, entomophagous insects, predatory birds), and chemical control methods (individual mound treatments, baiting, grits treatment, fumigation).

Key Findings

Solenopsis invicta is a serious, aggressive social insect pest with significant harmful impacts on crops, public safety, livestock, biodiversity, and ecosystems globally. Its control is challenging and expensive. Strict preventive and quarantine measures are crucial to avoid its invasion. If invasion occurs, IPM strategies are essential for effective management. Environmental factors, particularly temperature, significantly influence its foraging activities and adaptation.

Conclusion

Solenopsis invicta is a highly invasive pest with a growing global presence, causing substantial damage. Its ability to adapt to environmental conditions contributes to its success. Effective management requires strict preventive measures, robust quarantine protocols, and the continuous implementation of integrated pest management (IPM) strategies, encompassing biological, cultural, and judicious chemical controls. Early detection and identification are critical for successful control.
