    Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) has been the current topic of research for insect taxonomists and applied entomologists in India due to its invasiveness, rapid spread, morphological and biological variations and the need for establishing an effective control strategy. The biology of the mealybug P. solenopsis was studied on cotton under laboratory Cited by: COMSTOCK MEALYBUG. Pseudococcus comstocki (Kuwana)--Pseudococcidae (Contacts) GO TO ALL: Bio-Control Cases. Comstock mealybug became an extremely serious citrus pest in Israel in (Rivnay , Clausen , DeBach ). Clausenia purpurea Ishii was imported from Japan in , which resulted in the mealybug ceasing to be a pest.

    They also noted increased densities of the Argentine ant-tended grape mealybug Pseudococcus maritimus (Erhorn) accompanied by a serious reduction in its parasitoid populations. The cocktail ant Crematogaster peringueyi Emery is disruptive to natural enemies of soft brown scale Coccus hesperidum L., and vine mealybugs Planococcus ficus (Signoret).Cited by: The seasonal acquisition pattern of Grapevine leafroll-associated virus 1 (GLRaV-1) and Grapevine leafroll-associated virus 3 (GLRaV-3) by the grape mealybug, Pseudococcus maritimus (Erhorn), was determined over two consecutive years in a leafroll-diseased vineyard in the Finger Lakes region of New York.

Improve control strategies and better understand mealybug biology and ecology, as well as their role as vectors of plant pathogens. Mealybugs are named for the powdery These are the grape mealybug, Pseudococcus maritimus (Ehrhorn), K.

Daane (*). P Size: KB. To monitor adult activity, grape mealybug pheromone lures are available and are used in red delta traps to monitor for males.

There are two grape mealybug male flights per year. Monitoring the spring flight of grape mealybug males can be used to predict the emergence of crawlers of the summer brood and to time control measures.

Early detection of mealybug infestations allows implementation of appropriately timed control measures as soon as possible, and pheromone-baited traps are now used for monitoring Planococcus ficus (Signoret) (Hinkens et al.

The distribution in this summary table is based on all the information available. Biology and Management of Mealybugs in Vineyards. the grape mealybug, Pseudococcus maritimus (Ehrhorn), growing season on Pseudococcus viburni mealybug control in two commercial vineyards.

Pseudococcus meridionalis, a new species of mealybug found on grapes: biology, morphological and molecular characterization Conference Paper (PDF Available). Samples of adult mealybugs were obtained from 12 vineyards and all were identified as the grape mealybug, Pseudococcus maritimus.

Mealybug abundance and distribution was monitored monthly at 30 vineyard sites with either conventional, low or no pesticide input, in the Lower Yakima, Upper Yakima, Mattawa, Columbia Valley, and Walla Walla regions.

Pseudococcus maritimus. Pest description and crop damage The grape mealybug has a soft, oval, flattened, distinctly segmented body.

The adult female is to inch long, pink to dark purple, and with a white, mealy, wax secretion. Introduction. Grape mealybug, Pseudococcus maritimus (Ehrhorn) (Hemiptera: Pseudococcidae), is a quarantined pest on exported Californian table grapes for overseas markets such as Australia ().The insect has the potential to cause significant damage to grape production and economic losses.

It not only damages plants through feeding and secretion of Cited by: 4. Pseudococcus maritimus, the grape mealybug, is a scale insect species in the genus Pseudococcus infecting grapevines. It is also a vector of little cherry disease.

This mealybug gets its common name from the two long, waxy filaments protruding from the last abdominal segment of adult females (Figure 1). On grapevines, P. viburni can occur together with grape mealybug (Pseudococcus maritimus), longtailed mealybug (Pseudococcus longispinus) and vine mealybug (Planococcus ficus).

In both P. viburni and P. maritimus, live adult female elongate oval, mm long, coated with a white layer of mealy wax. Body with 17 pairs of slender white. Use the photos below to identify the various mealybug species. Pseudococcus includes grape (all growing regions), obscure (North Coast and San Joaquin Valleys, and longtail mealybug (Central Coast).

Species in the genus Pseudococcus have parallel sides, rounded posterior and anterior ends, and the filaments around the body are thin and long. Pseudococcus viburni (formerly Pseudococcus affinis (), and commonly known as the obscure mealybug and tuber mealybug) is a close relative of the grape mealybug (P.

maritimus) and a pest of the vineyards of New Zealand, the Central Coast of California, and the tea gardens of northern Iran. Unlike the grape mealybug, the obscure mealybug is not native to California, having most Class: Insecta.

The study indicated that CA treatments have potential to be developed for postharvest control of grape mealybug on harvested table grapes. Published by Elsevier B.V. Introduction Grape mealybug, Pseudococcus maritimus (Ehrhorn) (Hemiptera: Pseudococcidae), is a quarantined pest on exported Californian table grapes for overseas markets such.

Grapevine leafroll disease (GLD) is one of the most significant viral diseases of grapevines worldwide, described for more than a century (Hoefert and Gifford ), occurring in every major grape-growing region, and infecting wine, juice and table grape cultivars, as well as rootstocks (Maree et al.

).The pathogens associated with GLD are known collectively as Author: Monica L Cooper, Matthew P Daugherty, Daniel R Jeske, Rodrigo P P Almeida, Kent M Daane. Controlled atmosphere (CA) treatments with ultralow oxygen (ULO) alone and in combinations with 50% carbon dioxide were studied to control grape mealybug, Pseudococcus maritimus (Ehrhorn) on harvested table ultralow oxygen levels, 30 and.

The primary vector species in North America is the grape mealybug, Pseudococcus maritimus (Erhorn) (Hemiptera: Pseudococcidae) (Daane et al. ). P. maritimus overwinters as first-instar nymphs or eggs on canes and trunks and emerges around bud swell to feed and develop to adulthood and their offspring hatch in mid-summer (Grimes and Cone Cited by: Two mealybug species, the longtailed mealybug (Pseudococcus longispinus), and obscure mealybug (Pseudococcus viburni) occur in grapevines and deciduous fruit tree crops in Western Australia.

They are cosmetic pests in table grapes and deciduous fruit tree crops, but in wine grapes can affect fruit quality and yield, resulting in rejection by winemakers. (Signoret), whereas in Chilean vineyards, the most common species is Pseudococcus viburni (Signoret).

As the grapes go through veraison and continue to ripen, the mealybug moves to the grape clusters where it continues to feed and reproduce. One problem with mealybugs in regards to grape health is that when they are going through the process of .
