Understanding Mealybugs
What are Mealybugs?
Mealybugs (Pseudococcidae) are small, soft-bodied insects that feed on plant sap, causing damage and discoloration. These pests are commonly found on indoor plants, particularly those with soft, succulent leaves or stems. Mealybugs are typically white, cotton-like, and can be found on the underside of leaves, stems, or roots.
There are over 200 species of mealybugs, with the most common being the citrus mealybug (Planococcus citri) and the long-tailed mealybug (Pseudococcus longispinus).
Life Cycle of Mealybugs
The life cycle of mealybugs typically consists of three stages: egg, nymph, and adult. Female mealybugs lay eggs in protected areas, such as under leaves or on stems. The eggs hatch into nymphs, which go through several molts before reaching adulthood. Adult mealybugs can live for several months, reproducing and laying eggs throughout their lifetime.
