Parasites control pink hibiscus mealybug
For 4 years parasitic biological controls have been released in 34 Florida counties to control pink hibiscus mealybug (PHM). Fla. Dept. of Ag. and Consumer Services is calling the program a success. More than 2 million gnat-sized wasps have been released in every infested county. At study sites in Broward and Miami-Dade counties, adult PHM female populations dropped 97%. PHM feeds on sap and releases toxic substances that cause plant injury and sometimes death. PHM infestations are spread by wind, on infected plant material and by ants or other small insects.

Northwest gypsy moth populations grow
Statewide trapping programs in Washington and Oregon showed gypsy moth numbers grew in 2006. In Washington, 75 moths were trapped at 18 sites, twice the number caught in 2005. In Oregon, 66 gypsy moths were trapped, up from only 9 the previous year. The most moths were detected in Bend, Ore. (57 moths) and Kent, Wash., (43 moths). Oregon and Washington officials will coordinate eradication efforts. Gypsy moths attack more than 500 species of trees and are not considered established in these states.

Washington sees low pesticide water pollution
A study showed the amount of pesticides in 2 salmon-bearing watersheds was low and generally within acceptable levels. Wash. St. Dept. of Ag. and Ecology conducted the research, which included urban and ag. watersheds. During a 3-year period, 8 registered pesticides were found at levels that could potentially impact aquatic health. Herbicides were the most frequently detected in both urban and ag. watersheds. Insecticides were found more frequently in ag. watersheds than urban watersheds.

Where some people see a nursery, we see a body of complex parts and systems working together. This month we dissect a propagation facility. Only on GreenBeam.com.
