“…On the other hand, plant species such as Luffa cylindrica (L.) Roem. (Cucurbitaceae) (Bellé et al, 2019a) or Phaseolus vulgaris L. (Fabaceae) (Bellé et al, 2016;2019b;Sen and Aydınlı, 2021) have been described as highly susceptible to M. luci, and displayed considerably high Rf values. Other Meloidogyne spp., such as M. arenaria, M. hispanica, M. incognita and M. javanica, were also found parasitizing cucurbitaceous and fabaceous plants, so these plants can be generally classified as good hosts of RKN (Hillocks et al, 1995;Anwar and McKenry, 2010;Maleita et al, 2012;López-Gómez and Verdejo-Lucas, 2014;.…”

The root-knot nematode (RKN) Meloidogyne luci is included in the Alert List of the European Plant Protection Organization, because it has potential negative impacts on economically important crops. Identification of plant species/cultivars resistant to M. luci is important for its management. Susceptibility of 35 commercial plant species/cultivars, from nine families to a M. luci isolate from Portugal was evaluated in pot assays, assessing root gall index (GI) and reproduction factor (Rf) 60 d after inoculation, with tomato ‘Coração-de-Boi’ used as the positive susceptible experimental control. Presence/absence of RKN resistance genes was also determined in the tomato and pepper cultivars. One cultivar of cabbage, three of lettuce, ten of pepper, one of sugar beet, and all the cultivars of Cucurbitaceae (five), Fabaceae (two) and Poaceae (one) were susceptible to M. luci (GI = 4-5; Rf = 2.1-152.3). One cultivar each of carrot, passion fruit, lettuce ‘Cocktail’, cabbage ‘Bacalan’, ‘Coração’ and ‘Lombarda’, and spinach ‘Tayto’ were resistant/hypersensitive (Rf < 1; GI > 2). The tomato ‘Actimino’, ‘Briomino’, ‘Veinal’ and ‘Vimeiro’, which carried at least one copy of the Mi-1.2 gene, were resistant to the nematode (GI = 1-2; 0.0 < Rf < 0.1). These results indicate that the tomato cultivars have potential to contribute to reduction of M. luci populations in agro-ecosystems and improve the crop yields.

“…Meloidogyne luci is a polyphagous species with a wide host range including plants from several botanical families. It affects important crops such as potato, tomato, maize, bean and kiwifruit, among others [ 24 , 27 , 28 , 29 , 30 , 40 ]. As M. luci has been included in the EPPO Alert List of harmful organisms since 2017, due to its increasing importance and potential to cause serious damage to agriculture [ 41 ], it is crucial to have rapid and discriminative methods for detecting the presence of this emerging RKN.…”

“…This species shares some morphological and biochemical similarities with M. ethiopica and M. inornata, which led to the initial misidentification of several M. luci isolates in Europe as M. ethiopica [ 15 , 16 ]. Meloidogyne luci has been identified in various countries around the world, namely Argentina, Brazil, Bolivia, Chile, Ecuador, Greece, Guatemala, Iran, Italy, Portugal, Slovenia and Turkey, and is associated with more than 40 economically important crops, ornamentals, herbs and weeds [ 15 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ].…”

Meloidogyne luci has been identified in various countries around the world parasitizing economically important crops and, due to its potential to cause serious damage to agriculture, was included in the European and Mediterranean Plant Protection Organization Alert List in 2017. This species shares morphological and molecular similarities with M. ethiopica and M. inornata, and a M. ethiopica group was established. Although specific primers for DNA amplification of species belonging to the M. ethiopica group have been developed previously, primers were not species-specific and molecular markers for the specific detection of M. luci are still needed. The objective of this study was to develop a SCAR marker, for detection of M. luci and discrimination from other Meloidogyne spp., based on the intraspecific variability found in RAPD markers. RAPD screening of M. luci and M. ethiopica genome was used for the identification of a specific amplification product on M. luci, which was cloned, sequenced and converted into a SCAR marker. The specificity of the designed primers (Mlf/r) was tested and produced a fragment (771 bp) for all nine M. luci isolates with no amplification for the other nine Meloidogyne spp., including M. ethiopica and M. inornata. Additionally, the proper amplification of the M. luci SCAR-marker was also successful with DNA from galls of M. luci infected tomato roots. The results obtained in this study reveal that the specific molecular detection of M. luci was achieved and the developed methodology can be used for routine diagnosis purposes, which are essential to monitor M. luci distribution and spread, in order to implement future effective and integrated nematode pest management programs.

Goal. To analyze the phytosanitary risk of introduction, acclimatization, distribution and harmfulness of Meloidogyne luci for Ukraine. Methods. Pest risk analysis (PRA) was performed following the international standards ISPM 2, 11, 21; PM 5/2 (2) and the Ukrainian national protocol (Pylypenko et al., 2012). The conditions for acclimatization and further spread of nematodes were predicted using the Köppen-Geiger climate maps (Kottek et al. 2006). Data from EU national plant protection organizations and EPPO (EPPO Reporting Service 2016—2021; EPPO Alert List 2021), State Statistics Service of Ukraine (2016—2019), State Service of Ukraine for Food Safety and Consumer Protection, own research in previous years and literature sources were used for PRA. Results. The current distribution area of M. luci covers six countries in Central and South America, two in Asia and four in Europe, viz. Greece, Italy, Portugal and Slovenia. More than 36 species (agricultural, flower-ornamental, medicinal and others) can act as host plant of M. luci. The potential harmfulness of M. luci is based on 1) high level of fertility of females, 2) the ability to survive in adverse conditions and 3) the ability to overcome resistance in tomatoes which is based on the Mi-1 resistance gene. At least three possible introduction pathways of M. luci to Ukraine have been identified via the import of infected plants or plant products from the countries within the current geographical distribution area of M. luci, that increased from (2016—2019 some 2.4 times). Conclusions. Most of the imported plant products that could pose a risk for introduction of M. luci are coming from areas where it has been introduced recently, with low incidence and population densities. Therefore, the overall risk of introduction of M. luci into Ukraine is assessed as too low and it is recommended not to include M. luci in the Ukrainian national list of regulated pests.
