Lounsbury, C. P. (105) 
^Report of the chief, Division of Entomology, 1925-26^ Farming 
' in So. Africa 1(9): 334-338. 
Reports the natural spread of Aphelinus mali , except in the 
Cape Peninsula, where climatic conditions seem to retard its 
establishment. The parasite is ineffective in spring, but may 
control the woolly apple aphid by midsummer and so check it in 
seasons and places where the heat has not killed the aphids 
naturally; 
Newman, L. J. (106) 
Aphelinus mali . West Austral. Dept. Agr. Jour. 3(4): 486-487. 
Reports the introduction of A. mali to control the black citrus 
aphid ( Siphonophora sp.) in western Australia. After the first 
year the outbreak of the aphid had entirely subsided and practically 
every aphid had been parasitized. From these trees many colonies 
were distributed elsewhere. (Howard considers this a wrong 
determination of the aphid.)
