Pseudococcidae
What are Mealybugs?
Mealybugs are small flat-bodied insects, covered with a powdery-looking white coating; some have a fringe of white cottony threads attached to their bodies. Mealybugs feed by sucking on plant juices, then excrete a sweet, sticky substance called honeydew which attracts ants. Honeydew also provides a perfect medium for sooty mould growth.
A persistent offender is the Longtailed Mealybug (Pseudococcus longispinus)
Mild temperatures and high humidity are perfect conditions for mealybugs to breed, as a new generation of eggs hatches every 2-3 weeks, from spring through to autumn. Immature mealybugs prefer to hide in plant crevices or in the elbows between leaves and stems, so by the time you spot an adult the population can be bigger than you expect. Prolonged hot weather helps to reduce numbers.
Heavy infestations can occur on citrus, and grapes, plus daphne and other ornamental plants. Orchids and ferns can be vulnerable, especially in shadehouses. Mealybugs can also attack bulbs during storage, also the roots of some plants, such as polyanthus, liliums and callas.

Ants
Ants don't damage plants directly, but they can worsen the harm caused by sap-sucking pests like aphids and scale, by protecting them from predators. They're also a nuisance when they invite themselves indoors, so here's how to control the situation.
