Asian Giant Hornet Public Dashboard

Washington State Department of Agriculture.

The Asian Giant Hornet Public Dashboard shares detection and trapping data. Citizen scientists were able to view detections in real time, including the number of reported sightings and number of hornets confirmed by type. Coordinating this information provided input on future trapping and demonstrated the benefit of collaboration with citizen scientists. WSDA has indicated that citizen data sharing and bottle trapping efforts are crucial to protect Washington from this invasive species.

CAES Announces the Finding of Spotted Lanternfly in Southbury, Connecticut (Oct 15, 2019) (PDF | 60 KB)

Connecticut Agricultural Experiment Station.

The Connecticut Agricultural Experiment Station (CAES) in cooperation with USDA APHIS Plant Protection and Quarantine (PPQ) announce the detection of single live adult spotted lanternfly, Lycoma delicatula, in Southbury, CT. While no other spotted lanternflies were found upon surveying the immediate area, a live insect strongly suggests others may be present within easy transport from somewhere in the region. Additional surveys in the area are planned.

The spotted lanternfly is an invasive sap-feeding planthopper that was discovered in Berks County, Pennsylvania in 2014. It is native to China, India, and Vietnam. It attacks many hosts and has the potential to severely impact Connecticut’s farm crops, particularly apples, grapes, and hops, as well as a number of tree species like maple. Early detection is important for the protection of Connecticut businesses and agriculture. The public is urged to report potential sightings of this invasive pest to ReportSLF@ct.gov. For more information, see the CAES Pest Alert (PDF | 1.9 MB).
