oa Journal of the Entomological Society of Southern Africa - The discovery of a parasite of the Phoracantha beetle (Coleoptera : Cerambycidae) in the Western Cape



About the end of September, 1962, a pair of interesting parasitic wasps collected at Durbanville (C.P.), was submitted to the author for identification. On examination these insects proved to be Megalyra fasciipennis Westwood belonging to the small Australian family, Megalyridae. Froggatt (1907:90) recorded the larvae of A1. fasciipennis as parasitic in the wood-boring larvae of Cerambycidae of the genus Phoracantha Newman, an Australian genus infesting various species of Eucalyptus. Two species of this genus, P. semipunctata (Fabr.) and P. recurva Newman, which were accidentally introduced into South Africa, probably about 1900, are pests of economic importance, attacking mainly newly felled timber and sickly or dead trees.
