the Mealybug Destroyer was imported to the United States from Australia to control citrus mealybug infestations in California groves in 1891.
The little fellows and ladies did the job quite well, except that they are cold-sensitive and need to be reintroduced in spring in areas subject to long periods of cold. There's no need for reintroduction here, though, with our (usually) temperate winters. Mealybug Destroyers are effective predators of aphids and various soft scales.
Mealybug Destroyers are not content to attack their prey at just one stage of development. The adult female lays her eggs in the cottony egg sack of the mealybug. As soon as they hatch, the destroyers start snacking. Adults and young larvae prefer eggs, while older larvae will consume mealybugs, Aphids, and Scale at all stages.
One Mealybug Destroyer larva devours up to 250 mealybug larvae and Aphids. Like other lady beetles, the Mealybug Destroyer has proven its usefulness as an effective biological control agent. To this overlooked warrior, I would welcome this insect to my garden anytime
