Abstract
A new sample of drosophilids was obtained from Font Groga (Barcelona) on 9th October 2013. Flies were netted over 12 baits containing fermenting bananas placed along a trail from 4 to 7 pm. The number of flies classified according to species and sex is presented in Table 1. The most abundant species is D. subobscura (62.60%). This is expected because the sample was obtained during its autumn peak of expansion. Also interesting is to find again D. suzukii, and in a percentage similar (9.20%) to that obtained in 2012 sample. This species invaded recently many European regions and seems it is well established. We have finally estimated the species diversity using H" (Shannon diversity index) and J (Shannon uniformity index). The values obtained were 0.990 and 0.615, respectively. They are similar to those estimates obtained in the same site by Calabria in autumn 2007 and higher than those of Canals et al. in late autumn 2012.
