Location: Imported Fire Ant and Household Insects
2011 Annual Report
The objectives of this cooperative research project are to develop or identify environmentally compatible chemical controls to provide immediate, effective management of the invasive Caribbean crazy ant (CCA), Paratrechina pubens, and conduct an initial search for biological organisms that could provide long-term, sustainable control of CCA. Laboratory evaluations of commercial ant baits identified several baits that quickly kill small CCA colonies. However, baits which contain insect growth regulating (IGR) active ingredients were ineffective, probably due to inconsistent bait ingestion. New lures were evaluated for consistent consumption by CCA and will be formulated with IGRs for further assessment. IGR baits can potentially be more effective against pest ants with large, interconnected colonies. CCA from four regions in Florida were collected and sequenced. This information will be used to survey CCA populations by gene homology for pathogens that can potentially be utilized as biological control agents for self-sustaining population suppression.
