Nylanderia fulva (Mayr) (Formicidae) is an invasive pest ant that has been reported in Florida, Texas, Louisiana and Mississippi. Workers tend various honeydew producing hemipterans in Florida landscapes and natural areas. We sought to understand the seasonal foraging activities of N. fulva and its relationship with honeydew producing hemipterans. Twenty-two hemipteran species were collected from 15 different plant hosts sampled in Florida from Jul 2010 to Jul 2012. The relative density of hemipterans on 4 plant species [live oak (Quercus virginiana Mill; Fagales: Fagaceae), holly (Ilex cornuta Lindl; Aquifoliales: Aquifoliaceae), magnolia (Magnolia grandiflora L.; Magnoliales: Magnoliaceae), and sugarberry (Celtis laevigata Willd.; Urticales: Ulmaceae)] was compared to the relative density of N. fulva at the base or stem of the selected plants. The number of N. fulva and hemipterans on each plant species was positively correlated from spring through fall. Both N. fulva and hemipteran populations increased from May to Sep and decreased from Oct to Apr. In addition, Cinara juniperivora (Wilson) (Hemiptera: Aphididae) on southern red cedar and Toumeyella liriodendri (Gmelin) (Hemiptera: Coccidae) on magnolia were covered with carton shelters presumably constructed by N. fulva, suggesting that this ant potentially protects certain hemipterans species.
