A close relationship between the dopaminergic activity in the neostriatum and flexibility in behaviour has

genotype- environment interactions (BRAKEFIELD & KESBEKE, 1997). The data for development time (D = egg hatching to pupation in days), pupal weight (WF) and average egg weight (Wo) were used to calculate individual growth rate as log (growth rate) = (log(WF) - log(Wo))/D (c.f. NYLIN, 1992). Variation in
