Extract

In 1941 work was started in North America with a view to introducing into South Africa parasite species which might act as factors in the control of the insect pest, Loxostege frustalis Zell. (Pyraustidae), which destroys large areas of Karroo bush (Pentzia incana), an important sheep-fodder plant in South Africa (Taylor, 1940). Several nearly related species of moths occur in North America, one of them being Loxostege sticticalia L., a serious pest of sugar-beet in the Great Plains region. A number of parasite species have been recorded from this host both in America and Europe (Pepper & Hastings, 1941), and it was thought that several of these species occurring in North America might be suitable for introduction into South Africa after their hiolocv and life histories had been investigated.
