Burnett (1960) showed that the oviposition rate of the chalcid

wasp (Eurytoma obtusiventris and E.
1993) could find no direct hybrid effect on parasitism, but that chalcid
parasitism of cynipid galls was positively related to gall density and cynipid clutch size.
Some to be aware of are the predatory wasps (the kinds that sting) and the parasitic trichogramma, braconid, chalcid

The genera of chalcid

Because of their small size and lack of specialized mouthparts, certain chalcid
