The most serious pests are mealybugs that feed on [[citrus]]; other species damage [[sugarcane]], [[grapes]], [[pineapple]] (Jahn et al. 2003), [[coffee|coffee trees]], [[cassava]], [[fern]]s, [[cacti]], [[gardenia]]s and [[orchid]]s.  Mealybugs only tend to be serious pests in the presence of ants because the ants protect them from predators and parasites.  Mealybugs also infest some species of [[carnivorous plant]] such as ''[[Sarracenia]]'' (pitcher plants), in such cases it is difficult to eradicate them without repeated applications of [[insecticide]] such as [http://en.wikipedia.org/wiki/Diazinon diazinon]. Small infestations may not inflict significant damage. In larger amounts though, they can induce leaf drop.
