- ... Ectomyeolis ceratoniae Zeller (Lepidoptera: Pyralidae), carob moth, is a pest of several crops in South Africa. A laboratory culture was established from field-collected larvae infesting mummified pecan nuts. Biological parameters of larvae reared on an artificial diet were measured. The insect goes through five larval instars, and the head capsule sizes of the five instars were determined to be ≤ ...

- ... Recent studies have demonstrated that geographically isolated populations of Thaumatotibia leucotreta (Meyrick), an important pest of some crops in southern Africa, show minor genetic divergence. Because sexual selection can cause rapid evolution of male genitalia in insects, particularly in widespread, polyphagous species, differences in the morphology of these structures among different populati ...
