In Hawaii, local production currently accounts for about 18 percent of the total amount oflettuce consumed. Major production areas in Hawaii include Mountain View and Waianae for leafy and semi-head lettuces and Kula and Kamuela for iceberg types. Smaller areas of production are found throughout the state, and lettuce is also grown year-round in most home and community gardens. Hawaii's commercial production decreased by more than 35 percent over the past few years due to the tomato spotted wilt virus, a devastating, thrips-trans- mitted disease. More recently, silverleafwhitefly (Bemi- cia argentifolii) outbreaks have also affected lettuce pro- duction throughout the state. Production of hydroponic, greenhouse, "mixed," and specialty lettuces has recently become popular in Hawaii
