“…However, other pyridine alkaloids were also isolated and identified, including, 2-methyl-6-undecylpyridine, 2-methyl-6-tridecenylpyridine-isomer, 2-methyl-6-tridecenylpyridine-isomer, 2-methyl-6-tridecylpyridine, 2-methyl-6-pentadecenylpyridine-isomer, and 2-methyl-6-pentadecylpyridine (Chen et al 2019a). Liu et al (2017) suggested that by using the whole body solventsoaking method, an adequate amount of fire ant venom alkaloids can be extracted for chemical analyses and bioassays. Fox et al (2018) also developed a straightforward method for extracting within minutes aculeate S. invicta venoms by centrifugation.…”

Red imported fire ant, Solenopsis invicta, was first found in Taiwan province of China in 2003. To prevent transboundary expansion, the Chinese government has formulated various control strategies in the last 15 years to slow down the spread of S. invicta. Despite all efforts, S. invicta invasion has reached more than 390 counties of 13 provinces and two special administrative regions in China; at present, S. invicta remains at the stage of rapid expansion. The transnational entry of S. invicta is linked to imported logs and wastepaper coming mostly from the United States. In domestic settings, long-distance expansion of S. invicta relied on potted plant and turf transportation. Both monogyne and polygyne social forms of S. invicta were present in China with polygyne colonies as the dominant one. Data on population and breeding dynamics of S. invicta reveal the presence of two peaks annually with nuptial flights occurring throughout the year. Arthropods, plant seeds, and honeydew are important food sources of S. invicta, thereby causing negative impacts on the abundance, diversity, and richness of native arthropod communities. Fire ants are threats not only to agriculture and power facilities, but also to human health, with more than 30% of people having suffered from the sting and 10% having experienced an allergic reaction. To address the expansion of S. invicta, the National Fire Ant Detection and Management Union was established and the formulation and implementation of management policies were drawn. Plant quarantine becomes an essential step in fire ant management, whereas the two-step method of combing toxic baits and contact dust emerges as the forefront method crucial in managing S. invicta. The experience and lessons learned from fire ant management in China could benefit other countries when facing similar challenges.

“…In the secretion of venom and metapleural glands of species of this genus were identified compounds used as external immune defense, in the individual protection of the other members of the group and developing descendants (Vander Meer, 2012). Some species of this genus are known for their invading potential and called fire ants due to the burning sensation associated with their bites (Vander Meer, 2012;Liu et al, 2017). Identifying the action of the venom that can cause allergies in humans and testing different extraction methods have been the main objectives of the research conducted with Solenopsis ants.…”

“…The dissection of the glands and subsequent extraction with organic solvents, such as hexane, was the most used method among the selected studies. This technique allows the extraction of secretions in larger quantities, allowing the extraction of alkaloids and proteins successively from multiple ants, including those of smaller sizes like Solenopsis (Melo & Fortich, 2013;Liu et al, 2017).…”

“…The direct extraction of the gland with capillaries or through suction with the use of needle and syringe allows the extraction of pure and individual secretions for direct use, although the quantity is quite limited and the method is laborious (Liu et al, 2017). It was identified the use of this technique primarily for the chemical characterization of the secretions, in order to reduce possible contaminations that could interfere with the results.…”

Ants live under ideal microclimatic conditions for the development of microorganisms. As mechanisms to ensure the health of the colony and as a defense strategy, these insects developed exocrine glands that work in the production of antibiotics (chemical defense) and in the immune defense of the colony. This study aimed to describe the state-of-the-art on extraction methods, chemical characterization and the antibiotic potential of glandular secretions of ants. This is a review of the scientific literature between 1989 and 2017. A total of 52 articles were selected. These addressed the behavior, chemical characterization, the antimicrobial effect and evaluated methods of extraction. The most investigated genera are Atta, Acromyrmexand Crematogaster. The glands most reported in the articles involving extraction of secretions were Dufour, mandibular and metapleural. The most reported methods of extraction were gland maceration and extraction with (organic) solvents and direct extraction of the gland. Most studies evaluated secretions with respect to ant behavior. There is a paucityin the literature about the chemical characterization of most glandular secretions of ants, as well as for most taxa. The same deficiency is observed with regard to prospecting the antibiotic and antifungal potential of these secretions. for most taxa.
