Summary: The for (Sifor) gene plays a critical role in the behavioral transition between foragers and nurses of red imported fire ants. The expression patterns of Sifor and PKG vary in different castes, body sizes, ages, and tissues of fire ants. RNA interference-mediated Sifor knockdown induces the transition of foragers toward the nurse phenotype, while PKG activation results in the transition of nurses toward the forager phenotype.

Summary: This study identified and characterized five putative new viruses associated with Solenopsis invicta in introduced areas, including novel negative-sense single-stranded RNA viruses. The findings suggest a long-term association of these viruses with the invasive ant species and potential active replication within their bodies.

Summary: The study reveals that red imported fire ants exhibit circadian foraging rhythm activities at different temperatures, with maximum foraging occurring at 14:00. Temperature plays a significant role in foraging activity, with colonies showing preference for moderate soil temperatures. Fluctuating temperature impacts individual locomotor activity, but does not alter the rhythm activity.

Summary: This article studied the toxicity of Fluralaner against S. invicta and the involvement of metabolism-related enzymes in the metabolism process of Fluralaner. The results showed that Fluralaner was effective against S. invicta through topical application and feeding application, and cytochrome P450 monooxygenase and carboxylesterase might be involved in the detoxification of Fluralaner.

Summary: The study shows that worker ants of red imported fire ants deposit more soil particles on viscose or surfaces treated with essential balm or liquid paraffin in the presence of real food, and this behavior is observed in the field as well. Additionally, when no soil particles are available, the ants can only search and transport food on surfaces covered with sufficient quantities of soil particles.

Summary: This study found that 0.0125% fipronil bait is repellent against S. invicta workers, and higher concentrations of fipronil should be avoided in fire ant bait production. The effect of active ingredients and their concentrations on bait acceptance should be considered in future studies evaluating the effectiveness of fire ant baits.

Summary: The red imported fire ant (Solenopsis invicta Buren) is a highly successful and destructive invasive ant species. Utilizing the MaxEnt modeling approach and comprehensive surveillance data, the distribution of S. invicta in China resulting from climate change was predicted. It was found that S. invicta has been rapidly spreading to new areas annually, with transportation of seedlings and deployment of turfgrass being the major pathways. Efforts to control this pest have effectively reduced its occurrence and economic loss. The MaxEnt model predicts further expansion of S. invicta in China due to climate change, with moisture variables playing a key role.

Summary: Research has shown that harvester ants display clear preferences for certain cover crop seeds, with some seeds being more preferred than others. The removal rates of seeds by ants are also influenced by temperature and seasonal factors.

Summary: The red imported fire ant poses a significant threat to biodiversity, agriculture, and public health. Chemicals such as toxic baits and dust are commonly used for control, with dust providing faster results. This study tested the toxicity, horizontal transfer, and efficacy of bifenthrin and dimefluthrin dusts. The results showed that both bifenthrin and dimefluthrin were effective in controlling fire ants, with mortalities exceeding 80% in recipients after 48 hours of treatment.

Summary: Three botanical insecticides-matrine, rotenone, and pyrethrin-were tested for their toxicity and horizontal transfer in controlling the red imported fire ant Solenopsis invicta. Matrine dust showed highly effective horizontal transfer and has great potential for managing RIFA in organic farms, aquaculture farms of Hypophthalmichthys molitrix, and water resource regions.

Summary: The red imported fire ant, an invasive pest, has spread rapidly worldwide. By predicting the suitable areas for its growth in China, the study aims to provide reference for invasion prevention. Under current climate conditions, the suitable area is mainly located in the south and southeast of China. Future climate change is expected to expand the suitable area to higher latitudes.

Summary: The red imported fire ant is a prolific invasive species in the southeastern US that preferentially colonizes disturbed land and grassland habitats. Adaptive multi-paddock pasture management can increase fire ant mound abundance, but does not decrease arthropod diversity in the pasture.
