    Data has been collected from summer 2011 to 2016. Main reasons for NA values: - D. kuriphilus still not arrived in the site. - No galls were found during the field sampling. - Site has not been sampled in the correspondent year because of time, weather or money constrains. - T. sinensis not found in the galls Variable description: Year = sampling year. Coordinate, elevation, slope, aspect = average site characteristics. ts_arrival = T. sinensis arrival year. dk_arrival = D. kuriphilus arrival year. dk_parasitism_by_ts = D. kuriphilus parasitism rate by T. sinensis. Formula: (no. of T. sinensis/ no. of D. kuriphilus chambers) * 100 at gall level. dk_infestation = Percentage of attacked buds. Formula: no. of attacked buds / no. of total developed buds*100 (as presented in Kotobuki et al. 1985) at shoot level. ts_per_bud = number of alive T. sinensis individual calculated at bud level. dk_per_bud = number of alive D. kuriphilus individual calculated at bud level. dk_pot_per_bud = overall number (dead and alive) D. kuriphilus individual calculated at bud level. total_gall_nr_per_bud = average gall number per bud. chamber_per_galls = average D. kuriphilus chamber number per gall.
