Hoary cress (Lepidium draba L.) is an invasive perennial mustard (Brassicaceae) introduced to North America from Eurasia. In 2001 we initiated a program to investigate the potential for classical biological control of this weed in the US. Literature and field surveys for the arthropods associated with L. draba were conducted on both continents. Field surveys began in Europe in 2001, and in 2002-2003 standardized surveys were conducted in both Europe and the western US. These field surveys resulted in 80 new host records for L. draba in Europe, and 37 new host records in the US. Although total species richness was nearly four times greater in Europe, there were approximately equal proportions of oligophagous and polyphagous species in each range. Monophagous species were only encountered in the European surveys. The literature surveys revealed that the arthropod fauna associated with L. draba is fairly well known in Europe (175 species), but not in the US (eight species), where the literature was virtually derelict of host records. In both the literature and field surveys, the order Coleoptera contained the most species (>50%) in Europe, whereas the order Hemiptera contained the most species (>40%) in the US. Nearly one-half of the species found in literature and field surveys are flower or seed feeders and the other half are primarily foliage or stem feeders. Ten potential biological control agents were discovered from the surveys, of which four are currently being investigated at the CABI Bioscience Centre in Switzerland. The phenologies of these four species are briefly described. |
