Alert: New Pest Attacking Avocado

In February 2020, the Hawai‛i Department of Agriculture announced that the avocado lace bug has been reported on Hawai‛i Island.  Pseudacysta perseae, avocado lace bug, is a new state record for Hawai‛i and was first detected in Pearl City in December 2019. If you note anything suspicious, please take clear photos from various angles that you can use to begin communications with DOA folks.  Possible infestations on Kaua‛i, Maui, Molokai, or Lana‛i should be reported to HDOA’s Plant Pest Control Branch at: hdoa.ppc@hawaii.gov. Please include photos of the damage to avocado plants to help with identification. 

Avocado lace bug can be found on the underside of leaves.
