    Grape mealybug is by far the most common in eastern states. In California, two additional species may present problems, the obscure mealybug, Pseudococcus viburni, and the vine mealybug, Planococcus ficus. When poked, grape mealybug exudes a red fluid (ostiolar fluid), compared with clear fluid in the other two species.   “The most damage from vine mealybug is the infestation on clusters, although the spreading of leafroll virus can be also devastating through vine mealybug.” Distinguished from other mealybugs by its lack of a tail, vine mealybugs have been found in .

      In addition to the chemistries Kraus recommends to grape growers in Michigan, Walker suggests that California grape growers also look at adding a miticide to their rotations. Walker recommends Nealta ® miticide as an option to control mite outbreaks. In , growers also experienced problems with the mealybug, which can vector many viruses.

The grape mealybug was originally described as a pest of grapes, but it can attack most deciduous fruit crops. Since the s, it has become an increasingly severe pest of pear and apple. It is slow to spread from orchard to orchard, but once an orchard is infested, the infestation is difficult to clean up.

Pear-Grape mealybug. Pseudococcus maritimus. Pest description and crop damage The adult female is wingless and can be up to inch long.

It has a well-developed ring of waxy filaments around the sides of its body. The nymphs (or young crawlers) are purplish and covered with a powdery wax coating.

As they get older, the coating gets thicker. Grape mealybug contaminates fruit with cottony egg clusters, eggs, immature stages, adults, and honeydew. Sooty mold (a black fungus) may grow on the honeydew.

Of most concern in all regions is that grape mealybugs are important vectors of the grapevine leafroll virus. This insect can therefore spread the virus within and across vineyards.

Grape mealybug Pseudococcus maritimus: Almost identical in appearance to obscure mealybug. If poked (not punctured), it will release a reddish orange defensive secretion. Obscure mealybug secretion would be clear.

Ground mealybugs Rhizoecus spp. No obvious filaments. Live in soil. Hosts: Grapes, pears, pomegranate, and other fruit trees. Click on photos to enlarge; Grape mealybug Identification tip: Grape mealybugs (as all Pseudococcus mealybugs) are roughly 1/4 inch long, flat, oval shaped, and have a white waxy covering with wax filaments sticking out from the circumference of the body.

Longer filaments from the posterior end make these mealybugs appear to have "tails.". PEARS For heavy insect infestations, use higher dosage rates. For grape mealy bug control, use maximum dosage. Repeat applications as necessary in accordance with insect infestations and local and State spray recommendations.

The grape mealybug, Pseudococcus maritimus (Ehrhorn), is an important pest of table grapes in California's San Joaquin Valley. The mealybug causes direct damage by infesting grape bunches. In a medium saucepan bring the Welch's % grape juice, cinnamon and orange rind to a boil.

Place the pears upright (with stem on top) into the saucepan and simmer for minutes on medium to low heat.

Make sure to keep the pears moist by spooning the juice over them as they simmer. Remove pears from the sauce, reserve and cool completely. (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 feeding, they excrete honeydew.

Grape mealybug description Grape mealybugs (Pseudococcus maritimus) are small, white, flat-bodied plant suckers that appear to have a fringed mealybug lifecycle These pests have two generations each year. Eggs and crawlers overwinter under bark and in crevices.

In spring, they emerge and begin converging on young shoots, where they start to feed. Combine the sugar, lemon juice, wine, vanilla bean and jam in a bowl and stir until blended. Pour over the grapes.

Nestle the pears, cut side up, into the grapes. Bake until the pears are tender and the liquid around the grapes is thick and syrupy, about 50 minutes. Remove the pears and let stand for about 10 minutes. Remove and discard the. A Resource Book for the Pacific Northwest.
