Efforts by the USDA, Animal and Plant Health Inspection Service and the Secretariat of Agriculture, Rural Development, Fish and Food, National Service for Agri-Food Health, Safety and Quality (SENASICA), to look for Huanglongbing (HLB) and its vector, the Asian Citrus Psyllid (Diaphorina citri) in the northern states of Mexico resulted in the detection of suspicious psyllid specimens on June 19, 2008. The specimens were collected from sweet orange hosts in two urban locations of Tijuana, Baja California (-116.942089, 032.512569 and -116.940382, 032.522640).

The suspect insects were processed by technical personnel of the National Center for Phytosanitary Reference Entomology and Mite Laboratory. Through morphology and comparison to reference material, it was determined that the samples were Diaphorina citri.

Through the Plant Health State Committee of Baja California, SENASICA is following -up on this detection of Diaphorina citri in Tijuana by taking management measures to prevent the spread of the psyllid to other hosts. At this moment, the presence or absent of the pest are as stated in the ISPM Nº 8 “Determination of pest status in an area”: P4 Present: in all parts of the area where host crop(s) are grown and Transient: actionable under surveillance.
