Fact sheet White footed ants Technomyrmex spp. Technomyrmex is a genus of ants in the subfamily Dolichoderinae. With 98 species, it is one of the largest and most diverse ant genera in the Dolichoderinae. The genus distributed throughout the tropical and subtropical zones with most species occurring in the Oriental-Malesian and Afrotropical regions. One species, Technomyrmex albipes is an invasive ant now widespread throughout the tropics due to human activities. Identification of the Technomyrmex albipes requires expert examination as there are several other species that are similar. Many specimens previously identified as Technomyrmex albipes have subsequently been reidentified as Technomyrmex difficilis (difficult white-footed ant) or as Technomyrmex vitiensis (Fijian white-footed ant), which are already established in Australia. Where do they live? White-footed ants infest both urban and rural habitats, as they spread to other areas through commerce, such as nursery stock and shipping containers. Preferred nesting sites are near moisture and food sources that also provide protection from predators and harsh environmental conditions. Outdoors, this type of ant can likes to nest in moist microenvironments, including under loose bark or rocks, in decaying tree trunks and branches, and in old termite galleries. In homes, white-footed ants can be found nesting in wall voids, attics, under roof shingles, around skylights, and in kitchens and bathrooms. What do I look for? The pointed abdomen of white-footed ants is quite distinctive. The lower half of their legs is contrastingly light compared to the rest of their body. Inside houses they search in long trails for water. What can I do? If you suspect that you have found ants that are exotic contact Biosecurity SA or the Exotic Plant Pest Hotline.

In most tropical rainforests, very populous colonies of territorially dominant arboreal ant species defend absolute territories distributed in a mosaic pattern. Among the 29 ant species recorded, only nine had colonies large enough to be considered potentially territorially dominant; the remaining species had smaller colonies and were considered non-dominant. Nevertheless, the null-model analyses used to examine the spatial structure of their assemblages did not reveal the existence of an ant mosaic. Inland, up to 44% of the trees were devoid of dominant arboreal ants, something not reported in other studies.

Worldwide Spread of the Difficult White-Footed Ant, Technomyrmex Difficilis (Hymeno- Ptera: Formicidae)
Myrmecological News 18 93-97 Vienna, March 2013 Worldwide spread of the difficult white-footed ant, Technomyrmex difficilis (Hymeno- ptera: Formicidae) James K. WETTERER Abstract Technomyrmex difficilis FOREL, 1892 is apparently native to Madagascar, but began spreading through Southeast Asia and Oceania more than 60 years ago. In 1986, T. difficilis was first found in the New World, but until 2007 it was mis- identified as Technomyrmex albipes (SMITH, 1861). Here, I examine the worldwide spread of T. difficilis. I compiled Technomyrmex difficilis specimen records from > 200 sites, documenting the earliest known T. difficilis records for 33 geographic areas (countries, island groups, major islands, and US states), including several for which I found no previously published records: the Bahamas, Honduras, Jamaica, the Mascarene Islands, Missouri, Oklahoma, South Africa, and Washington DC. Almost all outdoor records of Technomyrmex difficilis are from tropical areas, extending into the subtropics only in Madagascar, South Africa, the southeastern US, and the Bahamas. In addition, there are several indoor records of T. dif- ficilis from greenhouses at zoos and botanical gardens in temperate parts of the US. Over the past few years, T. difficilis has become a dominant arboreal ant at numerous sites in Florida and the West Indies. Unfortunately, T. difficilis ap- pears to be able to invade intact forest habitats, where it can more readily impact native species. It is likely that in the coming years, T. difficilis will become increasingly more important as a pest in Florida and the West Indies. Key words: Biogeography, biological invasion, exotic species, invasive species. Myrmecol.

Technomyrmex Difficilis (Hymenoptera: Formicidae) in the West Indies
428 Florida Entomologist 91(3) September 2008 TECHNOMYRMEX DIFFICILIS (HYMENOPTERA: FORMICIDAE) IN THE WEST INDIES JAMES K. WETTERER Wilkes Honors College, Florida Atlantic University, 5353 Parkside Drive, Jupiter, FL 33458 ABSTRACT Technomyrmex difficilis Forel is an Old World ant often misidentified as the white-footed ant, Technomyrmex albipes (Smith). The earliest New World records of T. difficilis are from Miami-Dade County, Florida, collected beginning in 1986. Since then, it has been found in at least 22 Florida counties. Here, I report T. difficilis from 5 West Indian islands: Antigua, Nevis, Puerto Rico, St. Croix, and St. Thomas. Colonies were widespread only on St. Croix. It is probable that over the next few years T. difficilis will become increasingly important as a pest in Florida and the West Indies. Key Words: exotic species, Technomyrmex difficilis, pest ants, West Indies RESUMEN El Technomyrmex difficilis Forel es una hormiga del Mundo Antiguo que a menudo es mal identificada como la hormiga de patas blancas, Technomyrmex albipes (Smith). Los registros mas viejos de T. difficilis son del condado de Miami-Dade, Florida, recolectadas en el princi- pio de 1986. Desde entonces, la hormiga ha sido encontrada en por lo menos 22 condados de la Florida. Aquí, informo de la presencia de T. difficilis en 5 islas del Caribe: Antigua, Nevis, Puerto Rico, St. Croix y St. Thomas. Las colonias solamente fueron muy exparcidas en St. Croix. Es probable que la importancia de T. difficilis como plaga va a aumentar durante los proximos años en la Florida y el Caribe. The white-footed ant, Technomyrmex albipes MATERIALS AND METHODS (Smith), has long been considered a pest in many parts of the world.

Common Name White-footed ant; white-footed house ant. Scientific Name Technomyrmex albipes. Identification of the ant requires expert examination as there are several other species that are similar. Many specimens previously identified as Technomyrmex albipes have subsequently been reidentified as Technomyrmex difficilis (difficult white-footed ant) or as Technomyrmex vitiensis (Fijian white-footed ant), which also occurs worldwide. Distribution Worldwide. Asia, Africa, North and South America (restricted), Caribbean, Europe (restricted), Oceania. It is recorded from Australia, Cook Islands, Federated States of Micronesia, Fiji, Guam, Marshall Islands, New Caledonia, New Zealand, Niue, Palau, Papua New Guinea, Pitcairn, Samoa, Solomon Islands, Tokelau, Wallis and Futuna. Hosts Tent-like nests made of debris occur on the ground within leaf litter, under stones or wood, among leaves of low vegetation, in holes, crevices and crotches of stems and trunks, in the canopies of trees, and on fruit. The ants also make nests in wall cavities of houses, foraging in kitchens and bathrooms. Symptoms & Life Cycle Damage to plants is not done directly by Technomyrmex albipes, but indirectly. The ants feed on honeydew of aphids, mealybugs, scale insects and whiteflies, and prevent the natural enemies of these pests from attacking them.

Journal of Hymenoptera Research 53: 25–34. https://doi.org/10.3897/jhr.53.8904 Abstract Ergatomorph wingless males are known in several species of the genus Technomyrmex Mayr, 1872. The first record of these males is given inT. vitiensis Mann, 1921. In comparison with winged males, wingless males have a smaller thorax and genitalia, but both forms have ocelli and the same size of eyes. Wingless males seem to form a substantial portion (more than 10%) of all adults in examined colony fragments. Wingless males are present in colonies during the whole year, whereas the presence of winged males seems to be limited by season. Wingless males do not participate in the taking care of the brood and active forag- ing outside the nest. Males of both types possess metapleural gland openings. Beside males with normal straight scapes, strange hockey stick-like scapes have been observed in several males.

Exotic Invasive Ants a Threat to Business and Our Way of Life
Nursery levy at work: Building resilience and biosecurity capacity FACTSHEET Exotic Invasive Ants A threat to business and our way of life INTRODUCTION Exotic invasive ants (EIAs) can have a huge impact on the environment and humans. Invasive ants can have significant negative impacts on animal diversity in natural areas, reduce agricultural yields, can seriously impact human health and have social implications, e.g. changing the way outdoor areas are used and limiting time spent outdoors. As greenlife producers, it is important that nursery managers are aware of ant activity at their property, ensure they are not spread in container plants Odorous house ant, Tapinoma sessile, collecting tending scale insects. Photo by Susan Ellis, Bugwood.org. and report suspicious ant activity. This factsheet is designed to assist production nurseries to recognise ants that may be exotic to Australia. EIAs are important because they are area pests There are nine species (or genera) of EIAs considered as a that can be transported in container plants. In the priority species that have been endorsed by Plant Health Committee (Table 1). Other species are also considered a event that an EIA is detected and a quarantine priority but they are either under eradication or are widely put in place, businesses will need to meet established in Australia. There are many other species of certain requirements to continue trading. Such ants that are not present in Australia that are not considered high priority. The main reason for this is because they requirements could include pesticide applications do not have a history of invading new areas and causing of plants, pots and growing areas, keeping records economic, environmental or social impacts.

Bioinvasion and Global Environmental Governance: the Transnational Policy Network on Invasive Alien Species China's Actions O
1 Bioinvasion and Global Environmental Governance: The Transnational Policy Network on Invasive Alien Species China’s Actions on IAS Description1 The People’s Republic of China is a communist state in East Asia, bordering the East China Sea, Korea Bay, Yellow Sea, and South China Sea, between North Korea and Vietnam. For centuries China stood as a leading civilization, outpacing the rest of the world in the arts and sciences, but in the 19th and early 20th centuries, the country was beset by civil unrest, major famines, military defeats, and foreign occupation. The claimed area of the ROC includes Mainland China and several off-shore islands (Taiwan, Outer Mongolia, Northern Burma, and Tuva, which is now Russian territory). The current President Ma Ying-jeou reinstated the ROC's claim to be the sole legitimate government of China and the claim that mainland China is part of ROC's territory. The extremely diverse climate; tropical in south to subarctic in north, varies over the diverse terrain, mostly mountains, high plateaus, deserts in west; plains, deltas, and hills in east. After 1978, Deng Xiaoping and other leaders focused on market-oriented economic development and by 2000 output had quadrupled. Economic development has been more rapid in coastal provinces than in the interior, and approximately 200 million rural laborers and their dependents have relocated to urban areas to find work. One demographic consequence of the "one child" policy is that China is now one of the most rapidly aging countries in the world. For much of the population (1.3 billion), living standards have improved dramatically and the room for personal choice has expanded, yet political controls remain tight.
