Several species of mealybugs (Planococcus sp.) are common insect pests in greenhouses throughout the world. They can be especially troublesome in greenhouses featuring permanent plant collections, resulting in the need for regular application of insecticides to prevent pest populations from becoming well-established.Fortunately, it has been document that Mealybug Destroyer Beetles (MDB) are effective predators of citrus mealybug, the most common greenhouse mealybug species. Where mealybug populations remain relatively high, MDB has been reported to become established in interiorscape settings for periods exceeding five years.
A test population of one hundred MBD adults were released in the greenhouse complex in March of 2008 and successfully reproduced several generations through at least midsummer of 2008.
However, as with many predatory species, when food sources decline as a result of successful predation, predators will disperse and/or die. The result is a loss of control agents, reestablishment of harmful species, and need to purchase new predators, which can be expensive and time-prohibitive.
