Excellent article. Thank you for writing it! There are lots of folks here on the Big Island who have no idea what is going on with their avocado trees. The lace beetle has been around a while but not enough folks know about it. The photos you include are most helpful as there are many different ways it manifests. Leave a Reply. |
