USDA-ARS Entomologists “Turn Up The Bass” On Vineyard Pests

Pierce's Disease significantly impacts California's grape industry, costing millions annually. USDA entomologists are combating this by using insect mating calls to disrupt communication, preventing future damage. The process involves identifying mating calls and using disruptive signals, primarily in labs, then validating in fields. These signals, inaudible to humans, are studied using acoustics technology. The approach is effective, disrupting mating in vineyards and is compatible with current control methods, targeting specific species without harming beneficial insects.

What is the annual financial impact of Pierce's disease on the California grape industry?

• $200 million

• $104 million

• $500 million

• $50 million

What is the first step in the USDA's approach to disrupt insect communication?

• Use of acoustic technology

• Identification and description of mating calls

• Application of insecticides

• Release of natural enemies

What technology is used to listen to the insect communication that humans cannot hear?

• Radio frequency technology

• Ultrasound technology

• Acoustic technology from automotive and aerospace industries

• Satellite technology

How do the disruptive signals affect the glassy-winged sharpshooter populations?

• They have no effect

• They eliminate all insects in the area

• They increase the population

• They disrupt mating and control the population

What is a key advantage of using disruptive sounds over sprays?

• They are cheaper

• They are easier to apply
