Citrus greening disease research. Scientists performing a genetic (DNA) analysis of populations of psyllid insects collected in North and South America. These insects transmit the bacteria that causes citrus greening disease. Also known as huanglongbing, this disease causes mottled leaves and small, bitter fruits that remain partly green even when ripe. It is transmitted by the Asian citrus psyllid (Diaphorina citri). There is no cure. This analysis is intended to help identify natural enemies of the Asian citrus psyllid for use in a biological control program.
