SABCL research program Project Plan approved by OSQR in 2010 includes target weeds: Brazilian peppertree (Schinus terebinthifolius), Brazilian waterweed (Egeria densa), water primrose (Ludwigia hexapetala), water lettuce (Pistia stratiotes) and waterhyacinth (Eichhornia crassipes). Insect targets are cactus moth (Cactoblastis cactorum), little fire ant (Wasmannia auropunctata), Harrisia cactus mealybug (Hypogeococcus pungens), imported fire ants (Solenopsis invicta and S. richteri) and glassy-winged sharpshooter (Homalodisca vitripennis). Prior to the collection of their natural enemies, more in depth studies on the biology, ecology, genetics, and/or taxonomy of water primrose, cactus moth and little fire ant are required. These studies are planned as sub-objectives. Target priorities are set by Congressional mandates, as a result of stakeholder workshops, or by hierarchical decision with input from ARS National Program Leaders (NPLs), stakeholders, SABCL director and ARS scientists. Flexibility in this Project is needed to deal with new pest problems in the U.S., with concurrence of NPLs and ARS laboratories. SABCL functions as an overseas arm for several U.S.-based biological control programs on invasive pests of South American origin (except glassy-winged sharpshooter), conducting foreign exploration, collection and evaluation of potential biological control agents to be used in the U.S. Waterhyacinth, Brazilian peppertree, imported fire ants, and glassy-winged sharpshooter were also targets in the previous Project Plan and, except for Brazilian peppertree, Obj.1 and Obj.2 have already been accomplished; current work is limited to collecting and shipping of selected agents (Obj.3). Brazilian waterweed, water primrose, water lettuce, cactus moth, little fire ants and Harrisia cactus mealybug were added by NPLs during the implementation of the previous Project Plan and investigations are in different stages of progress; for the most recently-added targets (cactus moth, little fire ant and Harrisia cactus mealybug), specific approach and procedures for Ob.2 will be determined as soon as natural enemies are discovered, collected and identified. The general impact of work conducted at SABCL includes conservation of non-renewable resources by self-perpetuation of natural enemies; cost-effective suppression of target pests; decreased use of hazardous pesticides; improved environment quality; protection of natural ecosystems from invasive species, favoring biodiversity; sustainable production systems and land use; higher quality food and fiber; higher protection of human health; enhanced scientific understanding of successful biocontrol programs and integrated pest management.
