Yes they do. People who go there from South Africa, take their mealymeal with mealybugs in watertight containers so that the mealybugs can live there and not die in the rain.
Outdoor mealybugs are vulnerable to a variety of parasitic and predatory insects, including wasps, brown and green lacewings, and lady beetles.
Bugs are small insects. The two main bugs that attack a cactus plant are mealybugs [Pseudococcus spp] and root mealybugs [Rhizoecus falcifer]. Mealybugs feed on the cactus plant's precious juices that are found in the above ground shoots. Root mealybugs feed on the water and dissolved nutrients that the cactus takes in through its below ground roots. Either way, Both sets of bugs are taking away the fluids that the cactus most needs to survive.
Drenches, natural predators, and sprays are ways to protect other plants when mealybugs are found under plant leaves. Hoses and watering cans can be used to remove mealybugs from the undersides of leaves which they call home. Alcohol removes the wax which protects mealybug exteriors while such natural enemies as lacewings, mealybug destroyers will prey upon the pests until the populations are nowhere to be found in the immediate are.
Aphids, mealybugs, and scale are among the insects that will eat cactus plants.Specifically, the above list identifies predatory insects to watch out for outside in the garden and inside with houseplants. Aphids, mealybugs and scale do not just attack cactus plants. Their presence can spell trouble for just about any garden or house plant.

It would be difficult to keep a lady beetle in captivity. They feed on common garden pests such as aphids, mites, scale insects and mealybugs.
aphids or whiteflies get some ladybugs to eat them ****************** GET SOME LADYBUGS?? Please don't listen to that idiot It has mealybugs. Use Mealybug insecticides available as natural and chemical insecticides. Look for horticultural oils that contain neem oil to suffocate mealybugs. If you prefer chemical insecticides, look for products that contain permethrin or pyrethrin as the active
Aphids and mealybugs have been known to eat holes in fruit including oranges. Aphids if not controlled can cause a lot of damage to orange trees.
Orchids do not have any known defenses against being eaten. Aphids, scales, mealybugs, spider mites and some other insects and arachnids may eat orchids.
Aphids, citrus leaf miners, citrus psyllids, mealybugs and whiteflies are examples of bugs that feed on orange trees. Citrus leaf miners and citrus psyllids respectively feed on foliage and on leaves and stems while aphids, mealybugs and whiteflies sip on the host tree's internal, nutrient-rich xylem and sugar-rich phloem. Pathogens may be transmitted particularly by the psyllids and by the sap-sippers.
