Dactylopius opuntiae (Hemiptera: Dactylopiidae) as a Diet Source for Mass Rearing Cryptolaemus montrouzieri (Coleoptera: Coccinelidae).

Although natural enemies play an important role in most integrated pest management programs, biological control agents remain poorly adopted in food production systems primarily due to the high costs associated with their implementation. Cryptolaemus montrouzieri (Mulsant, 1853) is a very promising candidate for the biological control of mealybugs. However, mass rearing of this predator is critical to provide sufficient numbers so that effective control of mealybugs can be achieved.
