Common Pests
1. Scale insects - Santa Rita prickly pear is susceptible to different types of scale insects, such as cochineals and whiteflies. These insects appear as small bumps on the pads, and they suck sap from the plant, causing yellowing, wilting, and stunted growth. To manage infestations, use insecticides and biological control agents like ladybugs.
2. Spider mites - these tiny pests usually thrive in dry and dusty conditions. They prefer the underside of the pads and can cause yellowing and shriveling. Manage infestations by regularly watering the plant and wiping the pads with a damp cloth or spraying them with a strong jet of water. Acaricides and insecticidal soaps can also be used as a treatment.
3. Snout weevils - these insects feed on Santa Rita prickly pear roots and can cause stunted growth. They are nocturnal and difficult to control. To manage the infestations, handpick and destroy the adults and use nematodes or insecticides as a treatment.
