Necremnus artynes (Walker, 1839) (Eulophidae), a potential beneficial for the biological control of Tuta absoluta (Meyrick, 1917)
Since its initial detection in Spain in 2006, the gelechiid Tuta absoluta spread rapidly in the Mediterranean Basin and even elsewhere in Europe. It is now a major constraint for all tomato growers (Deneux et al., 2010). At this moment, the best strategy to manage the pest is based on the IPM system which includes : pheromone mimic, natural enemies, mass trapping and chemicals. Nevertheless, this strategy is sometimes unsuccessful depending on farming system, climatic conditions, countries etc... During the spring 2011 a serie of parasitoids reared from young larval stages of Tuta in Southern France (near Marseille) were identified by Andrew Polaszek as belonging to Necremnus artynes. Nevertheless, the individuals reared from Tuta show a high morphological variability and are somewhat different from the usual form.
