Black Scale Saissetia oleae (Olivier, 1791) (Insecta: Hemiptera: Coccoidea: Coccidae)
The black scale is an important pest of citrus and olive trees. Originally from South Africa, this scale is now distributed worldwide. In Florida, black scale is found on citrus, cultivated olive, avocado, and many popular landscape plants. It is likely that black scale, like many invasive pests, was imported to the United States on infested nursery plants. Based on their small size and the unique life history of scale insects, these insects are difficult to detect and control. This 4-page fact sheet was written by Morgan A. Byron, Jennifer L. Gillett-Kaufman, and Sandra A. Allan, and published by the UF Department of Entomology and Nematology, March 2015. (Photo credit: Lyle Buss, UF/IFAS)

Black Turpentine Beetle, Dendroctonus terebrans (Olivier) (Insecta: Coleoptera: Curculionidae: Scolytinae)
Black turpentine beetles bore into the inner bark of stressed or injured pines, where they breed and feed on phloem tissue. Adults are strongly attracted to volatile pine odors and readily breed in fresh stumps. In typical forests, infestations do not exhibit the rapid and devastating expansion characteristic of the closely related southern pine beetle, but in stands where stress conditions are frequent or persistent, black turpentine beetle can become a chronic pest and cause significant mortality over an extended period of time. Historically, black turpentine beetle has been a major pest of pines wounded or treated with herbicides in naval stores production. During the 1950s, black turpentine beetle damaged 37 million board feet of timber and contributed to the financial collapse of turpentine farms. This 5-page fact sheet was written by Albert E.

An ambrosia beetle Xyleborus affinis Eichhoff, 1868 (Insecta: Coleoptera: Curculionidae: Scolytinae)
Xyleborus affinis is one of the most widespread and common ambrosia beetles in the world. It is also very common in Florida. Like other ambrosia beetles, it bores tunnels into the xylem of weakened, cut or injured trees and farms gardens of symbiotic fungus for food. Females lay eggs in the fungus-lined galleries and larvae feed exclusively on the fungi. Recent studies have shown that Xyleborus affinis can vector the fungus responsible for laurel wilt disease, which is lethal to numerous species of trees in the Lauraceae family.

Contaminants in the Urban Environment: Dioxins
Dioxins are among the most toxic chemicals on the earth. They are by-products of a number of human activities such as combustion of fuels and wastes containing polyvinyl chloride (PVC), chlorine bleaching of paper products, and selected industrial processes. Current releases of dioxins by humans are due to the combustion of fuels and burning of household trash. The good news is that levels of dioxins in the environment have decreased in the United States throughout the past 30 years due to the improved emission controls and regulatory activities. But dioxins break down slowly, so they remain in the environment for a long time and accumulate in the food chain. Long-term exposure to dioxins can harm immune system, nervous system, endocrine system, and reproductive functions. This 7-page fact sheet discusses the sources, emission trends, and impacts of dioxins as well as the ways to minimize exposure to dioxins. Written by Yun-Ya Yang and Gurpal S. Toor, and published by the UF Department of Soil and Water Science, July 2015.
