How long is the mealybug life cycle?
six weeks to two months
After egg laying, females die and the eggs hatch in 7 to 10 days into tiny yellowish crawlers (nymphs). The long-tailed mealybug is slightly different in that females give birth to living young. The complete life cycle can take six weeks to two months depending on the species and the environmental conditions.
How do you control mealybugs on pineapples?
