‘Candidatus Liberibacter asiaticus’, causal agent of Huanglongbing (citrus greening), detected in Asian citrus psyllids, Diaphorina citri (Hemiptera: Liviidae), in Colombia
In late 2015, the bacterium ‘Candidatus Liberibacter asiaticus’, a causal agent of Huanglongbing (citrus greening), was detected in adult Asian citrus psyllids, Diaphorina citri (Hemiptera: Liviidae), infesting commercial and private Citrus sp. trees in Colombia. The pathogen has only been detected in the vector, D. citri, and not in citrus plants. Phytosanitary measures are being taken in an effort to prevent the spread of the pathogen.
‘Candidatus Liberibacter asiaticus’ is native to Asia and also occurs in the Middle East, parts of Central and South America, the Caribbean, and the United States. In the United States, it is present in South Carolina, Georgia, Florida, Louisiana, Texas, California, Puerto Rico, and the U.S. Virgin Islands and is under official control to limit its spread. ‘Candidatus Liberibacter asiaticus’ severely affects Citrus spp. Both ‘Ca. L. asiaticus’ and D. citri are listed as reportable in the PEST ID database (queried 4/6/16), and ‘Ca. L. asiaticus’ is listed as a pest of concern on the 2015 PPQ Prioritized Offshore Pest List.

First report of the thrips Hercinothrips dimidiatus (Thysanoptera: Thripidae) in the Netherlands
In October of 2015, female adults and larvae of the thrips Hercinothrips dimidiatus (Thysanoptera: Thripidae) were found infesting Aloe vera plants for planting in a production greenhouse in the Netherlands. This is the first report of H. dimidiatus in the Netherlands. A survey is planned to determine the distribution of the pest in the country.
Hercinothrips dimidiatus larvae feed and complete development on the upper surface of leaves, and adults feed on leaves and can also be found on the flowers. Feeding can result in discolored leaf spots, necrosis, and leaf death. Hercinothrips dimidiatus also infests Aloe arborescens (candelabra aloe) and has also been reported from Portugal and South Africa. It is not known to occur in the United States. Hercinothrips dimidiatus is not listed in the PEST ID database (queried 4/6/16).
