Not available – first paragraph follows: During urban grid surveys in September 1982, San Diego County biologists discovered a new invading whitefly on avocado. Ray Gill, insect taxonomist for the California Department of Food and Agriculture (CDFA), identified the new invader as Tetraleurodes sp. Steve Na-kahara of the United States National Museum then confirmed both the identification and the fact that the whitefly was new to California. Gill and Naka-hara agree that this whitefly is the same undescribed species known from the Caribbean, Central America, Florida, and Mexico.

Ray Gill, California Department of Food and Agriculture, provided taxonomic information and the photograph of the adult red-banded whitefly. George Opel, San Diego County Department of Agriculture, provided parasite recovery samples. The authors especially thank Paul DeBach, Division of Biological Control, UC Riverside.
