Extract

The matter offered for consideration in this paper deals entirely with one phase of the rearing of Chelonus annulipes Wesm., a larval parasite ovipositing in the egg of the European Corn Borer, Pyrausta nubilalis Hubn. This phase, the effect on the percentage of successful parasitism, of the age of the host eggs at the time of attack, is one of the more important factors determining the success or failure of laboratory rearing and distribution of this species.
