PEST MANAGEMENT
Gill's mealybug female adults
and crawlers in a " cotton
candy " nest in May.
Clean hulls compared to those from a badly infested tree
(2000 mealybugs/cluster).
Burkholderia spp. (Venerate, bacteria) applied in May,
or azadirachtin in May and Burkholderia spp. applied in
July, reduce the number of Gill's mealybug by 60% to 80%.
Some growers also release predatory lacewings.
Research on lacewings has not found conclusive evidence
that they are cost-effective for managing Gill's mealybugs
in pistachios.
Haviland encourages growers to try new methods on
their own, being sure to include an untreated control

group for comparison. For example, try both May/June
and July sprays on five acres and spray just in May/June
on the rest of the acreage. Other treatments to test may
include March treatments, releases of predators such as
lacewing larvae, or conservation biocontrol that promotes
natural enemy populations.
Applying the current best practices and having new ones
in the pipeline may help pistachio growers stay ahead of
Gill's mealybug.
