Research Project: Determining the Distribution and Natural Enemy Complex of the Roseau Cane Scale in Asia

Location: Beneficial Insects Introduction Research Unit

Project Number: 8010-22000-033-010-A
Project Type: Cooperative Agreement

Start Date: Feb 1, 2020
End Date: Jan 31, 2025

To discover and characterize natural enemies of the invasive roseau cane scale and determine their natural distribution range in Asia. Characterize their association with host plant genotype differences that may be related to scale insect colonization success.

• Work with co-PIs to produce a map of the tentative range of Roseau cane and RCS from museum and archive research. • Work with U.S. co-PIs to organize and conduct spring collections, assisting during their visits to Taiwan. Continue to collect at intervals through the season to provide specimens for genetic characterization and comparison of scale and parasitoid populations from native and introduced ranges for identification of a putative source population. Coordinate with US cooperators by supplying host plant samples collected in Asia for phylogenetic comparison with samples collected earlier in the US. • Rear out any additional parasitoids collected in Asia and send to US collaborators under the lead direction of USDA, APHIS.
