Interpretive Summary:

Technical Abstract: The first report of lebbeck mealybug in Florida occurred in 2009 from Palm Beach County on host plant dodder, Cuscuta exaltata. Since then there are 89 records of this species from over 40 host plant species in four counties in Florida (Broward, Martin, Miami Dade, Palm Beach). A decade later on June 14, 2019, a citrus sample with lebbeck mealybug was collected in Highlands County, Florida after noticing heavy infestation of white wax on branches and citrus fruits. This find represents a new county record and is the first occurrence of lebbeck mealybug in commercial citrus. The field guide depicts infestation of Nipaecoccus viridis, lebbeck mealybug on citrus: (a) white wax, (b) black mold, (c) misshaped fruits, (d) curled leaves, (e) naked eye view of female turned black in 70% alcohol, (f) dark purple liquid when mealybug is crushed, (g) mummies, (h-i) infestation hidden in calyx of fruits, and (j) life stages. Comparison of lebbeck to the citrus mealybug is shown as well as the natural enemies including beetles, wasps and other predators.
