A Meloidogyne ethiopica was discovered for the first time in Europe in Slovenia. It was identified by morphometrical analyses of J2, adult males and females and confirmed by PHAST. Identification was completed by comparison of small subunit rDNA sequences with those from other Meloidogyne species. The sequences of M. ethiopica populations from Slovenia and Brazil showed a 99.7% of sequence similarity score and clustered together with high bootstrap support. 22 new host plants for M. ethiopica were established in our tests; it can multiply on di- as well as on monocotyledonous plants.

It was demonstrated that M. ethiopica was able to survive in Slovenia in open fields located in regions with sub-Mediterranean and continental climates. M. ethiopica required 67, 48 and 36 days to complete the reproduction cycle at mean daily temperatures of 18.3, 22.7 and 26.3°C, respectively. At 13.9°C, M. ethiopica was not able to reproduce. We developed a correlation between T and the time needed for M. ethiopica to complete a reproduction cycle using a mathematical equation. Furthermore, 8 vegetable crops were tested for their suitability as hosts for M. ethiopica.

The effects of some insecticides and natural compounds (e.g.aqueous extract of Tagetes erecta and commercial natural product Azadirachtin on the M. ethiopica reproduction were assessed. Test plants treatments with natural compounds reduced nematode multiplication by nearly 3 – 6 times compared to control. Thiacloprid as well as Imidacloprid had no effect on nematode reproduction. Volaton G granulates was very effective - resulted in no nematode multiplication. The same result was observed on tomato with Mi gene for resistance to M. incognita.
