“…However, Teresani et al [22], using sticky traps, did not report B. nigricornis on carrots except for a field in La Rioja (38 psyllids from one sampling in 2012) and with very low populations in celery (2 psyllids in total from 3 samplings) and potato (2 psyllids from one sampling). Our results are also consistent with field surveys in carrot crops conducted in Tunisia were B. nigricornis and B. trigonica were the only two psyllid species found [21]. On the other hand, psyllid species surveyed by the 12.2 m suction trap on potato differed from those obtained by the other sampling methods used.…”

“…Despite this low risk of cross transmission, Lso is still of concern to potato producers in Europe because other psyllid species could potentially transmit Lso to, and within, potato especially in Mediterranean countries. For example, B. nigricornis Foerster, 1848, which is closely related to B. trigonica has been reported on carrot and potato crops [18,19,20,21], and has been tested positive for Lso haplotype E in the field [22]. This potential vector might represent a threat to European carrot and potato production, but very little is known about its population dynamics.…”

Psyllids (Hemiptera: Psylloidea) can transmit the phloem restricted bacterium ‘Candidatus Liberibacter solanacearum’ (Lso). In Europe, Lso causes severe losses to carrot and represents a threat to the potato industry. A rising concern is Lso transmission from carrot to potato and within potato, and this has driven the need for monitoring populations of psyllid species which could serve as vectors on both crops. This would provide a fundamental understanding of the epidemiology of Lso. Different sampling methods were used to survey populations of psyllid species in commercial carrot and potato fields in central and eastern mainland Spain from 2015 to 2017. Two psyllid species, Bactericera trigonica and Bactericera nigricornis were found on carrot and potato crops. In carrot fields the most abundant species was B. trigonica (occurring from crop emergence to harvest); whereas in potato crops the most abundant psyllid species was B. nigricornis. Depending on field location, the maximum psyllid populations occurred between June and October. Since B. nigricornis was found on both carrot and potato and is the only psyllid species able to feed and reproduce on both these crops in Europe, there is the potential risk of Lso transmission from carrot to potato.

“…Lso haplotypes D and E are vectored mainly by Bactericera trigonica 17 – 19 ; both haplotypes and their psyllid vectors can be found in the Mediterranean region 4 , 20 , North-Western Europe 11 , 21 , Israel 19 and Northern Africa 22 – 25 , but these haplotypes or their vectors are not known to be present in the UK 15 . Haplotype E has been found in infected commercial parsley seed sold in the UK 26 , but these seed lots did not originate from the UK.…”

The phloem limited bacterium ‘Candidatus Liberibacter solanacearum’ (Lso) is associated with disease in Solanaceous and Apiaceous crops. This bacterium has previously been found in the UK in Trioza anthrisci, but its impact on UK crops is unknown. Psyllid and Lso diversity and distribution among fields across the major carrot growing areas of Scotland were assessed using real-time PCR and DNA barcoding techniques. Four Lso haplotypes were found: C, U, and two novel haplotypes. Lso haplotype C was also found in a small percentage of asymptomatic carrot plants (9.34%, n = 139) from a field in Milnathort where known vectors of this haplotype were not found. This is the first report of Lso in cultivated carrot growing in the UK and raises concern for the carrot and potato growing industry regarding the potential spread of new and existing Lso haplotypes into crops. Trioza anthrisci was found present only in sites in Elgin, Moray with 100% of individuals harbouring Lso haplotype C. Lso haplotype U was found at all sites infecting Trioza urticae and at some sites infecting Urtica dioica with 77.55% and 24.37% average infection, respectively. The two novel haplotypes were found in Craspedolepta nebulosa and Craspedolepta subpunctata and named Cras1 and Cras2. This is the first report of Lso in psyllids from the Aphalaridae. These new haplotypes were most closely related to Lso haplotype H recently found in carrot and parsnip. Lso was also detected in several weed plants surrounding carrot and parsnip fields. These included two Apiaceous species Aegropodium podagraria (hap undetermined) and Anthriscus sylvestris (hap C); one Gallium sp. (Rubiaceae) (hap undetermined); and Chenopodium album (Amaranthaceae) (hap undetermined).

“…The risk of spreading this complex pathosystem in the Euro‐Mediterranean region is particularly high, considering how haplotypes of ‘ Ca . L. solanacearum’ were detected in Europe and the Mediterranean region not only on Solanaceae but also on Apiaceae, such as carrot and celery, vectored by various psyllid species, especially Bactericera trigonica Hodkinson and Trioza apicalis Förster (Munyaneza et al , ; Alfaro‐Fernández et al , ,b; Antolinez et al , ; Ben Othmen et al , ).…”
