It is a considerable agricultural pest, recognized as the most economically damaging pest of the date industry in California. In many regions around the world, it also damages many other high-value nut and fruit commodities such as almonds, pistachios, macadamias, pomegranates, and stone and pome fruits. Pheromone mimic lures are commercially available. In 2007, the California date "Phoenix dactylifera" industry produced 17,700 tons of dates on 5,900 acres, with a gross value of about $31.86 million. During
Fruit tree pollination a pollinator tree. Working from an old Spanish variety, "Tuono", researchers in 2008 started making available new self-fertile varieties that more closely match the qualities of the popular "Nonpareil" almond—including varieties "Lone Star" and "Independence". While self-fertile trees do not require pollen from a second tree variety for fruit / nut set, they still depend upon insect pollination for good production. Almond growers with self-fertile almonds report excellent nut set with half (or less) the number of bees in the field. Like apples, pears are self-incompatible and need to attract insects in order to be pollinated and produce fruit. One
