: Gardeners know that white flies are no stranger to California. But some people who monitor the agriculture industry are becoming very concerned about a certain white fly. It’s known as the Q-biotype. And it may be arriving in this country on imported poinsettia plants. But unlike the festive poinsettia, this white fly offers no Christmas cheer.
