Abstract Because of their small size and tolerance to many of the control procedures used for a wide variety of commodities, Acari species have become one of the fastest, unwanted pest travelers since the beginning of this century. This special issue includes eleven studies on adventive and invasive Acari species affecting major crops and livestock around the world. The nucleus for this special issue is formed by the presentations in the symposium on invasive mites and ticks organized at the International Congress of Acarology in Recife, Brazil (ICA-13), in the summer of 2010. This special issue illustrates the increased concerns about domestic and international invasive mites and ticks worldwide.

An introduction to adventive and invasive Acari and their importance in our shifting technological culture Adventive (non-native) species as defined by Frank and McCoy (1990) is a neutral term used to designate both immigrant and introduced species. By contrast, invasive species is a rather value-based term used to designate species that cause socio-economic or environmental damage (Wheeler and Hoebeke 2009). As in many other groups of organisms, concerns regarding domestic and international invasive and adventive Acari around the world have come to the forefront of many studies. During the summer of 2010, we organized and participated in a two-session symposium on Invasive Acari at the XIII International Congress of Acarology (ICA-13) held in Recife, Brazil (de Moraes et al.

2010). This was a unique opportunity to address some of the most relevant, recent invasion events which have involved Acari species. Special focus was placed on the relevance of genetic and ecological studies to understand the biology of these invasive species. The symposium addressed a wide diversity of topics, ranging from plant feeding mites in the Americas, via tropical cattle ticks on the island of New Caledonia, to the effect of environmental modifications driven by global change, their impact on the expansion of adventive and invasive Acari and their potential collateral effect on bio-control agents. A clear outcome of the symposium was the need for more in-depth studies in taxonomy, biology, ecology and genetics of adventive and invasive Acari on this planet of fast changing demographics and climate. This special issue covers several of the most aggressive, dynamic and rapidly spreading do
