On June 23, 2008 specimens of the Asian citrus psyllid (Diaphorina citri) were confirmed in Tijuana, Baja California on sweet orange and lime plants from a residential area of the city. Citrus psyllid specimens were processed by technical personnel of the National Center for Phytosanitary Reference National Station for Epidemiology, Quarantine and Plant Health (ENECUSAV) to corroborate the freedom of Huanglongbing (HLB). PCR techniques were used and the results were negative.
As a result, SAGARPA through SENASICA report on their website, that based on surveillance, sampling and diagnostic efforts in all citrus growing areas, the disease known as Huanglongbing (HLB) has not been found. Consequently, exports of lime and any other Mexican citrus to the United States and other countries continue without restrictions due to this disease. SENASICA will keep the citrus stakeholders informed about the measures taken in the surveillance program for HLB.
