No definite experiments were conducted in experimental control of the 
development, but during the warm weather many strawboard slips of 
parasitized larvae were placed in cold storage to retard the development 
of the parasites. In so far as it was possible to determine, they were 
placed in storage after the spinning of the parasite cocoon. This retar¬ 
dation of development had no apparent effect on the further development 
after removal from cold storage. It did seem, however, to reduce the 
activity and vitality of the resulting adults. L. J. Newman (18) records
