A leaf-curling mite, Floracarus sp. Mite feeding is associated with foliar disease which leads to defoliation. Studies are underway in Brisbane to investigate the biology of the mite and its host range. The larvae feed on the older foliage, pupating on the underside of the leaves. Preliminary host range tests are in progress.
Galls suppress new growth and reduce seed production.
Field host specificity and studies of its evolutionary biology with Melaleuca have been completed. This insect will soon be shipped to Gainesville, Florida for final quarantine host range testing on native Myrtaceae. A. Male and Female Fergusonina sp. B. Interior of Fergusonina gall with multiple chambers containing fly pupae and parasitoid consuming Fergusonina larvae. Our research program is funded in part by the South Florida Water Management District, Army Corps of Engineers, Florida Department of Environmental Protection, and the Southwest Florida Water Management District.
