Abstracts: Poster Julius-Kühn-Archiv, 465, 2020 121 and its formulated products in several worst-case semi-field tunnel and greenhouse trials (Dinter et al 2009). Conclusions When chlorantraniliprole was applied once to the soil followed by soil incorporation before P. tanacetifolia seeding at a predicted 20-year plateau concentration and then applied twice as foliar spray on pre-flowering or flowering P. tanacetifolia, all parameters assessed (mortality, flight activity, colony weight,

Also, there was no difference between the two chlorantraniliprole treatment scenarios T1 (pre-flowering exposure) and T2 (preflowering plus spray during flowering and during bee flight). Overall, no effects of chlorantraniliprole on bumble bee B. terrestris colonies including queen production and adult and larval mortality were found.
