PAS es 
M. A. Yothers, of Wenatchee, Wash., reports that the parasite 
Aphelinus mali Hald., which earlier in the summer had been introduced 
into a tree infested with the woolly aphid which was surrounded bya 
cloth cage, "multiplied rapidly until by mid-September * * * it had 
destroyed many thousands of aphids and many other thousands were in the 
earlier stages of parasitism. It was decided to liberate a few of these 
parasites upon near-by trees in order that they might have a chance to 
establish themselves under normal orchard conditions before winter. 
Between September 22 and 29, inclusive, a total of 19,500 Aphelinus 
mali parasites were captured and liberated. * * * The parasites were 
collected from the inside of the cloth covering of the cage * * * in 
lots of 500 each, except for the first three lots, which had 1,000 in 
each of them. The parasites were released upon woolly aphid-—infested 
trees in various parts of the district."
