The true <em>N. pubens<\/em> is also an invasive pest, but is apparently restricted to southern Florida. Worker ants of these two species cannot be distinguished morphologically, so clear identification requires examination of male specimens.<\/p>\n\n\n\n<p><em>&nbsp;<\/em><em>Nylanderia fulva <\/em>is also known as the crazy ant due to its quick and erratic movement. It is a small, reddish brown ant that forms huge colonies, and is a serious nuisance pest. (MacGown and Layton, 2010). <em>Nylanderia fulva<\/em> infests buildings and greenhouses. This ant can attack domestic animals, honeybee hives, and several crop plants; it can also displace native ant species (Hill et.al, 2013). It can aggregate in large numbers in electrical equipment and cause short circuits or clog switching mechanisms, resulting in equipment failure.<\/p>\n\n\n\n<p>The Tawny crazy ant is a social insect usually found in large numbers that lives in large colonies and seem to be indistinguishable from each other. Males and workers are similar in size while queens are larger. Colonies contain many queens, workers and brood (larvae and pupae). Pupae are naked (without cocoons). Colonies periodically produce winged male and female forms called sexuals, alates or reproductives. Foraging activity begins in spring and worker populations increase dramatically in density by mid- summer. (Nestor, 2002)<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><u>Worldwide Distribution<\/u>:<\/h5>\n\n\n\n<p><em>Nylanderia fulva<\/em> is native to South America, specifically southern Brazil and northern Argentina along the border of Uruguay and Paraguay (Kumar et. al., 2015). It has established in Anguilla, Bermuda, Colombia, Cuba, Guadeloupe, Martinique, Panama, Puerto Rico and the U.S. Virgin Islands. (Hill et. al., 2013)<\/p>\n\n\n\n<p>In the United States, it was first recognized as <em>N. fulva<\/em> near Houston, Texas in 2002, but this record is preceded by previous misidentifications as <em>N. pubens<\/em> in Florida. Currently, <em>Nylanderia fulva<\/em> has become established in the states of Texas, Louisiana, Mississippi, Alabama, Florida, and Georgia.<\/p>\n\n\n\n<p><strong><u>Official Control<\/u><\/strong>: <em>Nylanderia fulva has<\/em> not been listed as a harmful organism in any U.S. states or other nations (PCIT, 2018).<\/p>\n\n\n\n<p><strong><u>California Distribution<\/u><\/strong>:&nbsp; <em>Nylanderia fulva <\/em>has never been found in the natural environment of California.<\/p>\n\n\n\n<p><strong><u>California Interceptions<\/u><\/strong>:&nbsp; <em>Nylanderia species <\/em>were intercepted 107 times between July 2013 and January 2018 by CDFA through detection surveys, border stations, dog team inspections, and high-risk pest exclusion activities.<\/p>\n\n\n\n<p>The risk <em>Nylanderia fulva <\/em>(tawny crazy ant) would pose to California is evaluated below.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Consequences of Introduction:<strong>&nbsp; <\/strong><\/h5>\n\n\n\n<p><strong>1) Climate\/Host Interaction:<\/strong> <em>Nylanderia fulva <\/em>is omnivorous and its foraging trails widens&nbsp; as the temperature rises to 20\u00b0C. Foraging activity begins in spring and worker density can increase to millions during July \u2013 August and the number of ants remain high throughout fall. Nests can occur in leaf litter, soil, rotten logs, under potted plants, under rocks and along underground electrical circuits (Sharma et al., 2014).

Workers are also attracted to sweet parts of plants including nectaries, and damaged and over-ripe fruit. They also consume other insects and small vertebrates for protein (Nestor, 2002).

The larvae that emerge pass through three (workers) or four (males) instars and the larval stage lasts about 11 days. Workers carry pupae to the nest where they are piled into mounds. Adults emerge from pupae after 12 days. Nuptial flight activity has not been recorded until recently. New findings have confirmed that alate males fly throughout the year but females are produced only once a year (Wang, et al., 2016). Colonies spread by budding with breeding occurring at the periphery. The annual rate of spread by ground migration is about 20-30 m per month in industrial areas and about 207 m per year in rural landscapes (Nestor, 2002). <em>Nylanderia fulva<\/em> can be transported long distances by the movement of infested material including garbage, yard debris, compost, potted plants and bales of hay transported by truck, railroad and airplane.

Infestations can extend to sidewalks, buildings and gardens. These ants are capable of biting small livestock, causing them to die of asphyxia and can attack large animals around their eyes, nasal fossae and hooves. Their foraging and nesting behavior can cause short circuits in electrical equipment. Since this species feeds on the exudate of hemipteran insects, it can result in the disruption of biocontrol and cause losses from increased crop damage. This species has been reported to destroy honey bee hives in Texas by consuming brood, and then colonizing the hive (Harmon, 2009).

Larger ant populations have forced ground and tree nesting birds and other small animals to move out of the area (LeBrun et. al, 2013). Masses of these ants covering the ground and trees can cause wildlife to move out of the area. Ecological impacts by <em> fulva<\/em> include reduction in arthropod diversity, particularly native ant species. This ant can undoubtedly impact ecosystems in its adventive range and has the potential to cause cascading ecological impacts (Wang et al., 2016).
