The cochineal scale, Dactylopius opuntiae (Cockerell, 1896) (Hemiptera: Dactylopiidae), is reported from Jordan for the first time from several localities in the north of the country. This scale insect attacks the Indian-fig prickly pear, Opuntia ficus-indica (L.) Miller (Cactaceae), and plants are killed by heavy infestations. The distribution and the relative degree of infestations in Jordan are shown in a map. Voucher specimens of the collected samples were preserved in the University of Jordan Insect Museum. Slides of adult females were prepared, and digital images were taken to illustrate important diagnostic characters. World distribution, morphology, control methods, natural enemies and the probable means of the introduction of this serious pest are discussed.
