The time of emergence of the adult parasites coincides with the 

 time of emergence of the two broods of the codling moth. (Tables 

 LXXII andLXXIII.) Like the host, the parasite is evidently two- 

 brooded or possibly has a partial second brood.

The time and stage of the development when the codling modi 

 larvae become parasitized are not definitely known. Probably many 

 larva 1 are parasitized alter they leave the fruit and while in search of
