| Abstract: | The host specificity of the cephid stem-borerHartigia albomaculatus (Stein), was studied to determine its suitability for the biological control of European blackberry (Rubus fruticosus L. agg.) in Australia. Field observations indicated that the insect was specific toR. fruticosus, however laboratory tests showed that it can attack some cultivatedRubus and garden rose (Rosa spp.) varieties. Raspberry (R. idaeus L.) the most importantRubus crop in Australia, was not attacked, nor were 4Rubus spp. endemic to Australia. Observations in the Montpellier area, France, indicate thatH. albomaculatus has no significant detrimental effect on the vegetative reproduction of its host. |
