Imprinted Facultative Heterochromatization in Mealybugs
Genetica, 2003In lecanoid Coccids, or mealybugs, the male development is accompanied by the facultative heterochromatization of the entire, paternally derived, haploid chromosome set. This epigenetic phenomenon occurs in all the cells of mid-cleavage male embryos.

Genomic imprinting in the mealybugs
Cytogenetic and Genome Research, 2006The coccid insects (Hemiptera; Sternorrhyncha; Aphidiformes; Coccoidea; Pseudococcidae) are well suited to study not only the mechanisms of genomic imprinting but also facultative heterochromatization, a phenomenon well exemplified by inactivation of the X chromosome in female mammals.

Culturing of mealybugs is essential to rear the natural enemies, particularly parasitoids and predators for use in the field. Biological control programmes of mealybug species have relied on sprouting potatoes, pumpkins and butternut for rearing of both mealybugs and their natural enemies.

Mealybug wilt disease (MWD) is a serious field disease of pineapples worldwide that was first described in Hawaii in 1910. MWD is thought to be caused by a complex involving viruses, mealybugs and ants. The viruses are transmitted by mealybugs, which in turn are tended by ants. Although a number of distinct viruses have been associated with the disease,

Mealybugs are well-known sap-sucking insects which transmit plant viruses. They are omnipresent, polyphagous, can cause more damage as pests and are less uncommon as virus vectors. The feeding behavior of these vectors has profound ecological and evolutionary implications for the viruses they transmit, as the acquisition and inoculation of viruses ...

Annals of the Entomological Society of America, 1934
During studies of Pseudococcus gahani Green and Phenacoccus gossypii T. & Ckll., observations were made on the production of these two species of mealybugs that may be of interest to coccidologists. Schrader (1923) in his studies of Pseudococcus citri (Risso) determined that the species is nonparthenogenetic and found that the sexes occur in about ...

Females of several species of mealybugs produce pheromones which attract the males. Abdominal glands were suspected to be the source of pheromones in various species. Most of the mealybug pheromones are carboxyl esters of monoterpene alcohols and racemic mixtures were also observed to be effective than enantiomers.

Insecticide and Acaricide Tests, 1985
Abstract Greenhouse grown coleus in 4-inch containers artificially infested with mealybugs were selected for treatment. Insecticides were applied to runoff on 10 Jan using a 1-gal B&G compressed air sprayer. The treatments were evaluated beginning 1 wk after application by counting the number of mealybugs per plant.
