| The red imported fire ant, Solenopsis invicta Buren, is a severe invasive pest that has spread in many regions of China. In recent years, much research has been done on the foraging behavior of S. invicta, bringing new insight into S. invicta control. Here, we reviewed studies on the behavioral processes, mechanisms, and influencing factors of S. invicta foraging and their relationship with S. invicta management. S. invicta can collect and utilize food with various types, sizes, and components. The foraging processes of S. invicta can be divided into food searching, transport, and processing. Interestingly, food-burying, paving, and tool-using behaviors may occur during foraging. Several trail pheromones and key genes have been reported to regulate the foraging behavior of S. invicta. Moreover, various biological and abiotic factors can influence the foraging behavior and strategy of S. invicta. Based on the specific foraging behavioral patterns of S. invicta, it is expected to develop new monitoring and control techniques targeting S. invicta and therefore can be safer for non-targeted organisms. In future studies, more attention should be paid to behavioral patterns and the molecular and chemical basis of S. invicta foraging. In addition, it is essential to integrate basic studies of S. invicta foraging with control practices against this pest. |
