Pests are a thorn in the side of farmers and ranchers. For pistachio growers, those pests are causing a stink. Ag advisors in California say, unfortunately, the tree nut is all too inviting for stink bugs, but warn some can be beneficial.
“Most stink bugs are migratory, with the exception of the green stink bug, which overwinters in the orchard. Also, be careful that they don’t declare all stink bugs to be injurious because the gray, rough, shielded stink bug is beneficial, and it also lays eggs that are somewhat indistinguishable from all the other interior stink bugs,” said Bob Beeded, a UCANR Farm Advisor Emeritus.
The brown marmorated stinkbug is a native of Asia. It is believed that it first came to America by way of Pennsylvania more than two decades ago.
