Eradicating Wasmannia auropunctata (Hymenoptera: Formicidae) from Maui, Hawaii: The Use of Combination Treatments to Control an Arboreal Invasive Ant

摘要: A small infestation of Wasmannia auropunctata (little fire ant) was discov - ered on the island Maui, Hawaii in September 2009. After delimiting infestation, we treated it twelve occasions over course a year using two types granular baits for ground layer and paste bait containing indoxacarb (0.18% a.i.) vegetation. These treatments rapidly reduced W. population with only single ant recorded after five months treatment none thereafter. To date, one initiation treatments, no further positive detections have been observed tentatively report eradication this species from Maui. The key components program contributing to its success date baiting arboreal nests formulation designed use vegetation strategy repeatedly even ants could be detected conventional survey methods. response detection invasive Maui is successful example multi-agency collaboration cooperation necessary management. We recommend that future control attempts spe- cies include infested habitats.
