Mealybugs are the primary pest that feeds on orchids, Kondrat says. They suck the sap from the orchid, causing yellowing leaves, dropped blooms, and eventual plant death.
Mealybug females feed on plant sap, normally in roots or other crevices, and in a few cases the bottoms of stored fruit. They attach themselves to the plant and secrete a powdery wax layer (hence the name "mealy" bug) used for protection while they suck the plant juices. The males are short-lived, as they do not feed at all as adults and only ...
Because mealybugs have such few predators and their white wax is good at being a deterrent, populations of mealybugs can quickly rise. The predators can't always get to where the mealybug is, so the colonies can get so big that the juvenile cabbage trees can't handle them.
Paracoccus marginatus, commonly known as the papaya mealybug, is a small sap-sucking insect in the mealybug family, Pseudococcidae. It is found on a number of different hosts, including economically important tropical fruit trees and various ornamental plants .
Planococcus citri, commonly known as the citrus mealybug, is a species of mealybugs native to Asia. It has been introduced to the rest of the world, including Europe , the Americas , and Oceania , as an agricultural pest .
The ladybird Cryptolaemus montrouzieri is known as the "mealybug destroyer" because both adults and larvae feed on mealybugs and some soft scales. [18] Ants looking after their providers of honeydew tend to drive off predators, but the mealybug destroyer has outwitted the ants by developing cryptic camouflage, with their larvae mimicking scale ...
The species had spread to California, Mexico, Central America and to Florida in 2002. The adult female mealybug produces a blend of two compounds [1] that function as a female sex pheromone, highly attractive to males. [2] The pheromone can be used to trap males or to indicate the presence of a population of pink hibiscus mealybugs in the field.
The obscure mealybug has longer, thinner, and more crooked filaments than does the vine mealybug, making the obscure mealybug look comparatively untidy. [4] The most distinctive feature of the obscure mealybug is the set of two to four exceptionally long caudal filaments growing from the posterior of large nymphs and adult females.
