(Zingiberales: Zingiberaceae) leaf and rhizome essential oils were evaluated for their toxicity and repellency against invasive fire ants: red imported fire ants (RIFA), Solenopsis invicta Buren, black imported fire ants (BIFA), Solenopsis richteri Forel, and a reproductively functional hybrid (HIFA). Ar-turmerone was the major constituent of leaf (42.4%) and rhizome (40.4%) essential oils. A range of concentrations starting from 156 \u00b5g\/g until the failure of treatment were used. Removal of treated sand in digging bioassay was used as a criterion for repellency. Leaf essential oil showed significantly higher repellency at concentrations of 19.5, 9.8, and 4.9 \u00b5g\/g against RIFA, BIFA, and HIFA workers, respectively, as compared with control whereas rhizome essential oil was active at 39, 19.5, and 4.9 \u00b5g\/g against BIFA, RIFA, and HIFA, respectively. Ar-turmerone exhibited repellency at 19.5 \u00b5g\/g against HIFA workers whereas DEET (N,N-diethyl-meta-toluamide) failed at 39 \u00b5g\/g. Leaf essential oil showed LC50 values of 85.8, 97.7, and 182.7\u00b5g\/g against RIFA, BIFA and HIFA workers, whereas the rhizome essential oil had LC50 values of 127, 109.9, and 151.2 \u00b5g\/g against these species, respectively. Ar-turmerone, tested only against HIFA, with LC50 value of 57.2 was the most active compound. Bifenthrin, a commonly used pyrethroid, with LC50 of 0.03, 0.32, and 0.018 \u00b5g\/g was toxic against RIFA, BIFA, and HIFA workers, respectively. Both the essential oils and ar-turmerone showed toxicity and repellency against imported fire ants. Different formulations of these natural products will be tested to explore the use potential of these natural products under field conditions.<\/jats:p>","DOI":"10.1093\/jme\/tjad151","type":"journal-article","created":{"date-parts":[[2023,11,20]],"date-time":"2023-11-20T20:40:57Z","timestamp":1700512857000},"page":"191-200","source":"Crossref","is-referenced-by-count":9,"title":["<i>Curcuma longa<\/i> essential oils: toxicity and repellency against imported fire ants (Formicidae: Hymenoptera)"],"prefix":"10.1093","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5182-565X","authenticated-orcid":false,"given":"Abbas","family":"Ali","sequence":"first","affiliation":[{"name":"National Center for Natural Products Research, School of Pharmacy, The University of Mississippi , University, MS 38677 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farhan Mahmood","family":"Shah","sequence":"additional","affiliation":[{"name":"National Center for Natural Products Research, School of Pharmacy, The University of Mississippi , University, MS 38677 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed M","family":"Radwan","sequence":"additional","affiliation":[{"name":"National Center for Natural Products Research, School of Pharmacy, The University of Mississippi , University, MS 38677 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mostafa A","family":"Elhendawy","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, The University of Mississippi , University, MS 38677 ,","place":["USA"]},{"name":"Department of Chemistry, Faculty of Agriculture, Damietta University , Damietta ,","place":["Egypt"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahmoud A","family":"Elsohly","sequence":"additional","affiliation":[{"name":"National Center for Natural Products Research, School of Pharmacy, The University of Mississippi , University, MS 38677 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ikhlas A","family":"Khan","sequence":"additional","affiliation":[{"name":"National Center for Natural Products Research, School of Pharmacy, The University of Mississippi , University, MS 38677 ,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,11,20]]},"reference":[{"key":"2024112002170315000_CIT0001","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/978-0-387-46401-5_1","article-title":"The Indian solid gold","volume":"595","author":"Aggarwal","year":"2007","journal-title":"Adv Exp Med Biol."},{"key":"2024112002170315000_CIT0002","doi-asserted-by":"crossref","first-page":"279","DOI":"10.1080\/13880200701741138","article-title":"Larvicidal activity of turmerone-rich essential oils of Curcuma longa.
