The use of chemically treated corrugated bands as a supplementary 
control for codling moth. So. Austral. Dept. Agr. Jour. 38(4): 
453-456. 
Chemically treated bands placed on apple-tree trunks had 
caught great numbers of woolly apple aphids while they were 
migrating to the roots, but there were not so many in 1933-34, 
as Aphelinus mali had been numerous.

Some notes on the woolly aphis parasite ( Aphelinus mali Hald.). 
East Mailing /Kent7 Res. Sta. Rpt., 1933(21): 225-227. 
Describes the introduction and establishment of A. mali into 
Kent in 1933. It migrated against the prevailing winds and com- 
pletely eradicated the woolly apple aphid. Tar-distillate and 
lime-sulfur sprays did not appear to retard the parasite. In 
another center it was not effective and sprays had to be applied 
to control the aphid.

The author discusses the spread of A. mali , particularly in 
Germany. He believes that reported dissemination of consider- 
able distances is due to man, and not to natural distribution.

Aphelinus mali is often capable of wiping out the aerial forms 
of the woolly apple aphid.

Aphelinus mali introduced into Austria, survived the winter of 
1932-33 in only small numbers, owing to severe winter weather. 
Those enclosed in a tent around some trees survived much better.
