In spite of the cold winter of 1940-41 in Sweden, the young 
nymphs of the woolly apple aphid survived in cracks in the bark 
of apple trees, although older individuals did not. Aphelinus ' 
mali , which has been introduced into Sweden, has been able to 
survive the cold winters, but has not been generally effective in 
controlling the woolly apple aphid.
