*Recommended for control of Vine mealybug, Citrus mealybug, Obscure mealybug, Gill's mealybug,  Longtail mealybug, and other mealybug species. 

​

General Information

 

Anagyrus vladimiri are ready for release upon arrival. They should be released in the early morning after temperatures have risen to about 55 degrees F but below 95 degrees F.

 

Target Crops: Grapes, Citrus, Pistachio, Almond, Ornamentals, and others

Preferred Pest Stage: Anagyrus attack all mobile mealybug stages. The third instar is preferred for reproduction. Anagyrus host-feed, including on mealybug crawlers.

Sex Ratio: 50-60% female

Fecundity: Average 45 - 96 eggs/female/lifetime. With two generations per month, Anagyrus reproduction grows exponentially making them an even more effective parasitoid compared to some mealybug predators.

Longevity: Females can live 40 days and males 30 days under laboratory conditions with weekly feedings. They survive 14 days with one feeding.  

Handling: Until release, keep parasites in an insulated cooler with ice packs.

Release Rate: 

• Depending on infestation, release 2,000-5,000 Anagyrus adults/acre/season divided into multiple releases.  Additionally, augment with 300-500/fall season to prevent overwintering mealybug. 

• Greenhouse: Apply 1 female per 5 square feet of greenhouse. Repeat every two weeks with ongoing evaluations.  

Release Method: Distribute evenly throughout with additional taps in active, infested areas. Release approximately every 3, 6, or 12 rows depending on crop.

Timing: Early releases are critical once day temperatures rise above 55 degrees.  Start in known infested areas. Begin releasing as soon as mealybug is exposed. This is typically in late winter or early spring after the mealybug leaves the bark. Begin late-February/early March up to mid-May depending on weather, location, and crop.  Additionally, release in September-October to reduce mealybug populations that are present after harvest, before they return to the roots, lower trunk, or ground to overwinter.  Anagyrus larvae overwinter inside their mealybug host.
