Abstract

A study of plant-parasitic nematodes in the Botanical garden at Ghent University in Belgium revealed the presence of two tropical nematode species, i.e. Scutellonema brachyurus and Meloidogyne incognita. Scutellonema brachyurus was recovered, only once, for the first time in Belgium from Musa basjoo and is morphologically characterized. M. incognita, forming galls on Hedychium greenii, was recovered in all seasons over three consecutive years and is morphologically and molecularly characterized. Although no unequivocal evidence was found to indicate that these nematodes pose a current threat in Belgium, in the light of climate change, it is crucial to improve our knowledge of potential tropical nematode activity in more Northern countries.

Highlights

The presence of tropical nematodes has been reported from several Mediterranean or more southern European countries (Wesemael et al, 2011; EPPO, 2019)
This study reveals the presence of S. brachyurus and M. incognita in Belgium, species known to be prevalent in warm areas, especially in tropical regions (CABI, 2019)
The Belgian population of the spiral nematode belongs to the S. brachyurus group type B according to Van Den Berg et al (2013)

Summary

Introduction

The presence of tropical nematodes has been reported from several Mediterranean or more southern European countries (Wesemael et al, 2011; EPPO, 2019). Tropical nematodes do not yet pose a problem in the more northern parts of Europe, including Belgium. According to Bebber et al (2013), there is clear evidence of a general, climate change-driven, poleward migration of pests and plant pathogens, a movement that can include tropical plant-parasitic nematodes. Our survey revealed the presence of Scutellonema brachyurus and the tropical root-knot nematode Meloidogyne incognita (Kofoid and White, 1919) Chitwood, 1949 for the first time, respectively, on banana
