: 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. It is pesticide resistant, and it could wreak havoc on many important agricultural plants, including poinsettias and cotton.
San Diego County is at the heart of this matter, because it is at the heart of the poinsettia industry.
