One of the reasons people love orchids is that the flowers stay on the plant for a long time. ... Mealybugs are the primary pest that feeds on orchids, Kondrat says. They suck the sap from the ...
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 ...
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.
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.
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 .
They are a pest, including in eastern North America where the species is the main mealybug pest. The Comstock mealybug feeds on apples, pears, peaches, and many ornamental plants. [1] The honeydew stops photosynthesis while also damaging the plant. Chemicals have been used to reduce the population of the species with 80% efficiency although it ...
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.
