Grape Mealybug Lure

Latin Name: Pseudococcus maritimus

Lure: Gray Rubber Septum

Lure Active Ingredient: (R,R)-trans-(3,4,5,5-Tetramethylcyclopent-2- en-1-yl)-methyl 2-methylpropanoate

Field Life: 4 weeks

Trap to Use: Paper or Plastic Delta Trap

Monitoring Strategy: Researchers recommend that one trap be placed in every 30 acres. Attach traps to the trellis wires so that they are in the cluster area. Label the trap with the block name and row number of its location and the dates it remains in the vineyard. Check traps for the presence of male grape mealybug every 2 weeks through November. Check with Cooperative Extension or Master Gardener for local information and recommendations

Cultural and Physical Control: California researchers recommend that one trap be placed in every 30 acres. Attach traps to the trellis wires so that they are in the cluster area. Check traps for the presence of male Grape Mealybug every 2 weeks through November. Check with Cooperative Extension or Master Gardener for local information and recommendations.

Distribution: Found throughout the Mediterranean region, South Africa, parts of Asia and Mexico. Now also found in California.

Hosts: Grape, citrus

Description: Adults: Female, unarmored, flattened, oval dark orange or pink body covered in a mealy white wax coating. Length about 3/16 in. (5 mm). Check USDA to learn how maritimus differs from Obscure Mealybug P. viburni (Maskell). One method of distinguishing between them is to poke a female with a sharp point without puncturing the body. Maritimus will secrete a reddish orange defensive fluid. Viburni secretes clear fluid.

Larvae: Yellow to orange-brown crawlers.

Eggs: Oviparous, yellowish-white to orange, within an egg sac under loose bark or in the upper portions of the trunk.

Life Cycle: Two generations per year and overwinters as an egg or crawler. In spring most grape mealybug crawlers move toward the base of spurs and then onto expanding green shoots, reaching maturity in mid-May to early June. Most females return to old wood to lay eggs that hatch from mid-June to July. First generation crawlers then move out to the green portions of the vine to feed on fruit and foliage in late June or early July; immature mealybug are mostly seen through July. Adult females will appear in late summer and early fall. The majority of the females return to the old wood to lay the overwintering eggs.
