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.

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 ...

Experiments on a mealybug infesting apple and a mealybug infesting catalpa
20141. The developing time of the mealybug from catalpa exceeded that of the mealybug from apple. 2. In no experiment did cross-breeding of the mealybug from apple and from catalpa take place. 3. Each mealybug was able to live successfully on both hosts. 4.
