The fascinating chromosomal cycle leading to facultative heterochromatization in the mealybugs has been a challenging system for mechanistic understanding of the phenomenon of genomic imprinting and epigenetics. The elegant cytological dissection of the various processes reported in the literature is equally fascinating for the researchers of current ...

METHODS OF MOLECULAR DISCRIMINATION OF CITRUS MEALYBUG FROM VINE MEALYBUG
Acta Horticulturae, 2011The correct identification of pests is a basic requirement in IPM strategies for crop protection. In the case of Planococcus species the discrimination between similar taxa using morphological features is sometimes difficult because it is based on few microscopic characteristics not easily detectable.

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.

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,

Identification of the pheromone of the Comstock mealybug
Life Sciences, 1980Abstract The Comstock mealybug, Pseudococcus comstocki (Kuwana) is a tiny insect that is a serious agricultural pest of citrus, pomegranates, and other fruit in California and elsewhere throughout the world. The fungus that forms on the insect secretions causes severe smutting and results in economic losses to fruit growers.

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 ...

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.

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.

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 ...

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.
