Larvae expressing Mgat1dsRNA.Scer\UAS.cUa under the control of Scer\GAL4He.PZ reduced encapsulation of eggs of the avirulent wasp L. clavipes (51.8% encapsulation compared to the 100% seen in wild-type larvae). Larvae expressing Mgat1dsRNA.Scer\UAS.cUa under the control of Scer\GAL4C833 show normal levels of encapsulation of L. clavipes eggs.
