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.
They may disperse over the host, especially toward tender growing parts, or be carried away by wind, man, or animals. The nymphal stages appear much like the female in form, but the female nymphs have three instars, while male nymphs have four instars. The last instar of the male is an inactive stage with wing buds within a cocoon of mealy wax ...
Identification of mealybug species in the Planococcus genus has been difficult due to an unusually high amount of intraspecies morphological variation. In the 1980s, entomologist Jennifer Cox at the British Museum discovered that the offspring of a single female raised on the same host will develop differently based on environmental conditions.

Planococcus ficus, commonly known as the vine mealybug, is a species of mealybug, belonging to the family Pseudococcidae, native to tropical and subtropical regions. [1] The vine mealybug is found in Europe, Northern Africa, Southern Africa, the Americas, and the Middle East.
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]
Green scale is transported to new areas on infected plants. There should be a thorough inspection of planting material for scale and other insects before it is introduced into a greenhouse. [ 9 ] Certain entomopathogenic fungi have been shown to affect green scale but attempts to infect healthy insects with these fungi have been unsuccessful. [ 2 ]
Do you know what chigger bites look like? The tiny mites may leave behind small, itchy red bumps around your ankles that can be easily confused for other types of insect bites. "They tend to be in ...
