A tiny, aphid-like bug called the Asian Citrus Psyllid is threatening to destroy California's citrus industry. The danger comes from a disease the bug sometimes carries called Huanglongbing (HLB) or "citrus greening disease." When a tree becomes infected by HLB the fruit becomes bitter and misshapen and the tree eventually dies. HLB has severely damaged Florida's citrus industry, where the state has been unable to control the spread of the disease. Larry talks with University of Riverside entomologist Elizabeth Grafton-Cardwell and lemon grower Link Leavens about the problem.
