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.

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.

Replication of euchromatin and heterochromatin in a mealybug
Chromosoma, 1971Asynchronous DNA replication of euchromatic (E) and heterochromatic (H) chromosomes and heterochromatic B chromosomes (B) were studied in the mealybug, Pseudococcus obscurus Essig (Homoptera: Coccoidea). The study was carried out on mycetocytes of adult females and on spermatocytes of mid-second instar males by employing tritiated thymidine labeling ...

Exochomus flaviventris Mader is considered to be the most active predator of the cassava mealybug Phenacoccus manihoti Matile–Ferrero in Central Africa. The response of experienced gravid female coccinellids to the odor of cassava plant (var. Zanaga), unparasitized mealybugs, plant–mealybug complex with or without feeding prey (parasitized or not), and

Mealybug wilt of pineapple (MBW), first described in Hawaii in the early 1900’s (46), is now reported in most areas of the world where pineapple is grown (6, 7, 13/14, 22). The circumstances surrounding MBW epidemics are complex involving multi-trophic interactions between mealybugs (MB), ants, mealybug predators and parasites, pineapple plants and ...

Mealybugs are found attacked by various natural enemies in nature. The outbreak of mealybugs was observed in many instances with the application of broad-spectrum insecticides, which might have disturbed the activity of natural enemies particularly parasitoids and predators.
