From parasite-infested material collected from the Oriental Peach 
Moth Laboratory at Moorestown in June, Prof. J. J. Davis, of Purdue 
University, reports that 500 Macrocentrus ancylivora were obtained for 
liberations in orchards in Indiana, and that 22 per cent parasitism of 
this species has already been obtained in collections made for recovery 
of the parasite. 
Dr. Philip Garman, of the Connecticut Agricultural Experiment 
station, spent several days late in July collecting strawberry leaf- 
roller larvae at the Moorestown Laboratory. He obtained 7,000 heavily 
parasitized larvae, and hopes to get a heavy emergence of Macrocentrus 
ancylivora for liberation in orchards in Connecticut. 
Dr. H. W. Allen and A. C. Hcdson, who have been investigating 
the infiuence of parasitism on infestation by the oriental peach moth in 
New Jersey, have found the parasitism of twig-—infesting larvae to have 
been very high, in some collections reaching 100 per cent. The infesta- 
eomeOr Lruit up to August 25 had not exceeded ll per cent, including 
both visible and invisible injury, for any variety.
