Biological invasion are considered as one of the most serious threats to ecosystems around the world, the spread of introduced, non-native species in the United States are causing major environmental damages and losses adding up to $120-137 billion per year (Pimentel et al. 2000; Pimentel et al. 2005). The cost associated with management of invasive species, which includes prevention, monitoring, mitigation, control and restoration, are huge (Westbrooks 1998). Majority of the native US species, about 42% on the Threatened or Endangered species lists are at risk primarily because of alien-invasive species (Pimentel et al. 2005). Within the United States the impact threat from invasive species is not uniform for all geographic locations, Hawaii and Florida being more prone to higher species rate of arrival compared to the other states with 15 species per year on average (CSIR-UCR 2014).
