Number of galls examined and of those containing the brood of species of aculeate Hymenoptera (Vespoidea, Apoidea) and their parasitoids (Hymenoptera: Chrysidoidea; Diptera: Asiloidea).

We found 20.6% of one year old reed galls positive for the nests of aculeate Hymenoptera. Indicated are the number of individuals hatched in the rearing bags, number of nests positive for each species found as revealed by longitudinal cutting of the reed galls, and their relative proportions within the total datasets. Species marked by asterisks are parasitic.Number of galls examined and of those containing the brood of species of aculeate Hymenoptera (Vespoidea, Apoidea) and their parasitoids (Hymenoptera: Chrysidoidea; Diptera: Asiloidea).
