Elongate hemlock scale, Fiorinia externa Ferris (Hemiptera: Diaspididae), is an armored scale insect native to Japan and eastern Asia. This insect was first documented in the United States in 1908 in Queens, NY, and has since spread throughout most of the eastern United States. Though the primary hosts of the pest, hemlocks and firs, do not occur in Florida, there are concerns that elongate hemlock scale coming into the region on cut Christmas trees may disperse and establish on conifers that do occur in Florida. Of specific interest are two endangered species, Florida torreya (Torreya taxiflora) and Florida yew (Taxus floridana), which are native to a small region in northwestern Florida. Also of concern are Florida forestry species, Florida Christmas tree species, and species used for ornamental plantings in Florida. What can Florida do to protect its native conifers and farmed trees from the elongate hemlock scale? Find out in this 5-page fact sheet written by Adam Dale, Travis Birdsell, and Jill Sidebottom and published by the UF/IFAS Entomology and Nematology Department.
This 9-page illustrated fact sheet by James D. Ellis discusses the merits of using nucleus colonies, or nucs, which are smaller versions of full-sized Langstroth hives.

Phytoplasma diseases of palms are a major threat to the Florida nursery and landscaping industries. Historically, lethal yellowing has killed millions of coconut palms throughout the Caribbean and has been causing decline of over 30 species of palm in Florida since it was introduced to the state in the first half of the 20th century. In 2006, lethal bronzing disease was discovered on the west coast of Florida near Tampa. Currently, the only two management options available for control of phytoplasmas is an aggressive sampling strategy followed by consistent tree removal and injections of oxytetracycline hydrochloride, or OTC. This 2-page fact sheet written by Brian W. Bahder and Ericka E. Helmick and published by the UF/IFAS Entomology and Nematology Department seeks to provide a source of information and instruction on the injection of OTC into palm trunks.
Pest control professionals and homeowners throughout Florida and the southeastern US are seeking effective options that are safer for people and the environment than some conventional synthetic pesticides. There is also rising interest in organic gardening, which relies on natural pesticides. This 13-page fact sheet describes natural products for use in residential landscapes and gardens. Written by Matthew A. Borden, Eileen A. Buss, Sydney G. Park Brown, and Adam G. Dale, and published by the UF/IFAS Department of Entomology and Nematology, revised September 2018.
Resistance to insecticide or miticide is a worry for landscape managers. Around the world, chinch bugs, leafminers, and other insect and mite pests have become resistant to dozens of insecticides, but with diligent insecticide resistance management, we can still maintain long-term effective chemical control. With few new modes of action coming onto the market, landscape managers need to be good stewards of existing products. Ultimately, resistance management means reducing exposure of pests to any one pesticide. Fortunately, there are many ways to prevent resistance and still control pests of ornamental plants and lawns, and this 6-page fact sheet written by Nicole Benda and Adam Dale and published by the UF/IFAS Entomology and Nematology Department explains how.
