Neonicotinoid Insecticides And Bee-Decline: Association Effort Addresses The Issues
To help you answer questions that will undoubtedly arise following the unfortunate and accidental bee-kill that happened in Oregon this past June, our floriculture industry associations have produced a letter and a frequently asked questions document you can use. Some groups have called for the prohibition of neonicotinoid insecticides, and in many cases they are trying to identify the use of these insecticides as the sole cause for Colony Collapse Disorder (CCD) of European honeybees.The phenomenon, sometimes referred to by the more general term, Bee Decline, occurs when worker bees do not return to their hive after foraging. Recent reports by the USDA and EPA suggest that the cause of CCD is likely much more complicated than any one factor. The new documents developed by ANLA, OFA and SAF attempt to shed additional light on this difficult issue by recognizing the importance of protecting our environment and our pollinator population, […]

Greenhouse Pests 101: Whitefly
Whiteflies are one of the most easily identified of all greenhouse insect pests. True to their name, whiteflies are tiny (about .06 inches long) whitish insects with four white wings. There are several species of whiteflies, collectively infesting more than 250 ornamental plants. Favorite hosts include lantana, poinsettia, nicotiana, tomato, bean, hibiscus, eggplant and geranium. Whiteflies cause damage by sucking sap from the leaves of plants. Heavily infested plants will weaken and leaves will turn yellow and drop. Whiteflies, like other insects that feed on sap, excrete a sugary substance called honeydew, which is quite sticky. Black sooty mold grows on the honeydew and further discolors the leaves. Eggs, nymphs and adults can be easily seen on the undersides of the leaves. Adults will fly up quickly if the leaves are brushed. Because of this, even a low-level infestation, while not immediately harmful to the plant, will turn off customers. […]
