Table 3. Populations of D. quercusvirens associated with Q. geminata (Qg) and Q. virginiana (Qv) used in the present study, along with study site location and the population means ± SE and sample sizes (in parentheses) for each trait measured (HTL = hind tibia length [asexual generation], GPC = galls per compound stem gall, MGD = mean gall diameter per individual gall that forms compound gall, HP = host preference of the asexual generation females for Q. virginiana [ = 1 − host preference for Q. geminata]).
