Technical Abstract: The concept of a mobile containment greenhouse/laboratory was originally developed by ARS scientists 10 years ago. A prototype unit was built and deployed for citrus canker studies in Miami. The second generation prototype, a self-contained, semi-mobile, computer-controlled unit, was constructed by USDA, APHIS, PPQ. The 3 inch double walls of the greenhouse are constructed of custom extruded aluminum framing sheathed with double layer Lexan panels. Environmental parameters (temperature, lighting, CO<sub>2</sub>, watering) are continually monitored and controlled by a computer data acquisition and feedback control system. Basic laboratory equipment includes: a refrigeration/freezer, biosafety cabinet, incubator, autoclave and a HEPA air filtration unit. An emergency generator functions automatically as a power back-up and can also provide full electrical power in the absence of local electricity. Other features include a holding tank for effluent, metal diamond plate floors, central channel drain, irrigation/fertigation system for the greenhouse plants and external field plots. This new mobile unit will be used immediately for citrus canker research, but more importantly, can be replicated and rapidly deployed as needed by APHIS for additional emergency programs as outbreaks of new high consequence quarantine pests and pathogens occur in the U.S.
