Bugs & Shrubs Buzz

Ficus blister galls are causing defoliation and branch die-back of many of our heritage, old-time Cuban laurel ficus trees (Ficus microcarpa). This is a difficult pest to manage, but there is some success with trunk injections of emamectin benzoate and to a lesser degree imidacloprid. Stay tuned for new information on how to better manage these blister galls caused by a tiny wasp, Josephiella microcarpae. Please share with me if you have found a treatment that gives excellent control!

Laurel Wilt (Avocado) Disease is in Collier County: In mid-April, Scott Krueger, Ag. Inspector with the Division Plant Inspection (FDACS), reported an avocado tree that had died from this new disease. I have had about 3 calls in the last few weeks about dying redbays. This is most likely due to laurel wilt disease which has been killing trees in the southeastern US since 2002. Key symptoms are dead leaves which do not drop off and frass extrusions which resemble cigarette ash extruding from the trunk.
The redbay ambrosia beetle is attracted to volatiles naturally emitted by healthy living trees as well as injured avocado (Persea americana) and redbay (Persea borbonia) trees. Please see the fact sheet “Laurel Wilt: A Threat to Redbay, Avocado, and RelatedTrees in Urban and Rural Landscapes”.  Ambrosia beetles (there are about 5 native ambrosia beetles which can also spread this disease as well) bore into the sap wood and infect trees with the fungus which clogs the vascular pipelines and causes death.
SANITATION (tree removal and disposal) is highly important to suppress the spread of this disease.
