First report of the Opuntia cochineal scale Dactylopius opuntiae (Hemiptera: Dactylopiidae) in Morocco

The Opuntia cochineal scale Dactylopius opuntiae (Cockerell) (Hemiptera: Dactylopiidae) causes severe damage to prickly pear (Opuntia ficus‐indica (L.) Miller). This scale insect was first detected in Morocco in 2015 during sampling in the cactus crop in the Sidi Bennour region (120 km north‐west of Marrakech). Methods for sampling, preservation and identification are described. Although this scale insect can be used for the production of the natural dye carmine, the damage it can cause is considerable. A pest risk analysis should be carried out and the ensuing management measures implemented to prevent severe economic and ecological losses.
