Mealybugs are insects in the family Pseudococcidae, unarmored scale insects found in moist, warm habitats. Of the more than 2,000 described species, many are considered pests as they feed on plant juices of greenhouse plants, house plants and subtropical trees and also act as a vector for several plant diseases.
The adults and larvae of these insects eat scale insects, especially mealybugs. Females lay their eggs among the egg sac of mealybugs. Larvae feed on mealybug eggs, young crawlers and their honeydew. They become adults in 24 days, after four larval stages and a pupal stage. The life span is two months. [7] [8]
