Abstract:

The prevention and control of Solenopsis invicta epidemic has always emphasized early detection, early reporting and early control, and entrusting a third-party professional organization to carry out the monitoring and survey of S. invicta is a favorable means to find S. invicta. The present study reviewed the process of specialization monitoring and census of S. invicta in Deqing County, China, from 2021 to 2022. Three outbreaks were found in this investigation. The habitat types were wastelands near the flower and timber trading market, nurseries and green lawns in the community, and the invasion history was all within 2 years. Because the epidemic was detected early, its occurrence area and extent were not large, the later investment cost will be low and the emergency culling effect will be remarkable. If the local diffusion distance analysis method was used to predict S. invicta, and S. invicta was found after 1, 3, and 5 years, its diffusion area and eradication cost would increase significantly. Therefore, we suggest that the economic benefits of early detection of S. invicta through professional monitoring and census are significant, and the monitoring and survey of S. invicta should be normalized in the future, and the publicity of science popularization should be intensified to give full play to the role of the public in discovering and reporting the S. invicta epidemic.
