| Asian Citrus Psyllid Arrives in California |
|
The Asian citrus psyllid, Diaphorina citri (Hemiptera: Psyllidae), arrived in southern California from Mexico in 2008. It is a tiny (1/8 inch, 3 mm in length) mottled brown insect that is about the size of an aphid. It attacks citrus and very closely related ornamental plants in the family Rutaceae (mock orange, Indian curry leaf, orange jasmine and other Murraya species). This pest attacks new citrus leaf growth and, because of the salivary toxin that it injects, causes the new leaf tips to twist or burn back. However, the more serious damage that it causes is vectoring the bacteria (Candidatus Liberibacter asiaticus and related species) that cause Huanglongbing (HLB or citrus greening) disease. Huanglongbing causes shoots to yellow, assymetrical leaf mottling, and abnormally shaped fruit with bitter juice. The disease can kill a citrus tree within 3 to 5 years, and there is no known cure for the disease.

Tomato yellow leaf curl is a new disease in California. It has the potential to devastate tomato production in California. An IPM brochure contains information on the disease, illustrates disease symptoms and the whitefly vector, and tells people what to do if they find plants with symptoms that look like tomato yellow leaf curl.

| Diaprepes Citrus Root Weevil |
 The citrus root weevil, Diaprepes abbreviatus, is a large colorful weevil that is native to the Carribbean Islands. This weevil was accidentally introduced into Florida in the 1960's where it has caused extensive damage. It has been intercepted in shipments of plants to California. This weevil will feed on about 270 different plants including citrus, guava, loquat, holly, and other ornamentals.
This pest is a significant threat to both urban and agricultural trees and plants. If you see the adult weevils or plants that they may have damaged, please contact
the California Department of Food and Agriculture's Exotic Pest Hotline at 1800- 491-1899.
