| description | <em>Opuntia dillenii</em> (Ker Gawler) is an invasive plant species in Bundala National Park. The outstanding success of the cochineal insect, <em>Dactylopius</em> spp. in bio-control of the prickly pear, <em>Opuntia</em> spp. has been investigated worldwide. The present study reports the emergence of <em>D. opuntiae</em> as a pest of <em>O. dillenii</em> after several decades of its introduction to Sri Lanka. The intensity of infestation was 100% along three of the five transects surveyed and the overall damage was more than 50%. This recent outbreak of <em>D. opuntiae</em> may have resulted from an unnoticed existing population of <em>D. opuntiae</em> in the vicinity. |
