Abstract

Dotted paropsine leaf beetle (DPLB) is an invasive eucalyptus pest native to Australia. Its first U.S. detection was in California in 2022. DPLB feeds on several eucalyptus species, with blue gum as its primary host. Feeding damage includes semicircular notches on leaf edges, defoliation of young leaves, and dieback of shoot tips. DPLB poses a threat to eucalyptus plantings across the western U.S. and to cut foliage producers in Utah.
