Mealybug Destroyer

Mealybug Destroyer

The mealybug predator, better known as Cryptolaemus montrouzieri, was originally brought to America from Australia over 100 years ago by Albert Koebele, an early champion of biological controls. Used to help control an outbreak of the the citrus mealybug — mission accomplished! — these small lady beetles are deadly as adults and larvae to aphids and soft scale insects as well as mealybugs.

Mostly black with a tan front, the adult Cryptolaemus searches out the waxy, sometimes cotton-like egg cases of its prey. It then lays its own eggs nearby. The larvae emerge within five days and begin to feed on the eggs as well as the young crawler stage and the pest’s honeydew . After three larval stages, the mealy bug larvae enter the pupal stage before becoming egg-laying adults. The process takes approximately three weeks. Adult females will lay some 400 eggs over their two month life span.
