ABSTRACT. 1. A rainfall simulator is described that was used to investigate the effects of rainfall on the cochineal insect Dactylopius opuntiae (Cockerell). This species occurs in discrete colonies that are protected by a copious covering of opaque‘woolly’wax, and is the most important biological control agent of the prickly pear cactus, Opuntia ficus‐indica (L.) Miller, in South Africa.
