For reducing mortalities in effecting a parasite recovery program for the European corn borer, fall collections of larvae of the single-generation strain should not be made prior to the borers entering hibernation. When collected, the borers should be placed under storage conditions favorable for dormancy. The hibernating borers should be allowed to remain under these conditions without contact moisture until the last of April. After this time, they may be placed under developmental conditions with weekly applications of contact moisture.
