A new acoustic instrument can kill pests for wine grape growers researchers at the University of Florida have found a new way to prevent pests from invading crops - you just need to be a competent "listener"

through high-tech acoustic instruments, vineyard owners can hear the sound of pests gnawing at the roots of wine grapes, so that they can know which part should be "heavily treated". Growers call this pest, which eats the roots of wine grapes, grape root drillers

will Sanders, a graduate of Entomology from UF University, was the main operator of the study, and he also formulated the outline of the project

he said that one day, using the sound to determine the number of pests in 2016 can save money for vineyard owners, so as to provide customers with cheaper wine grapes and wine. The wine grape industry can bring us $20million to Florida every year

grape root driller is a moth similar in shape to wasps, and is the most important pest in the southeastern United States. The larvae of the grape root driller live in the root of the grape vine and feed on the root of the grape, which poses a threat to the growth of the whole wine grape

the currently popular chlorpyrifos insecticide on the market is very effective against this pest, but it is also harmful to birds, fish and bees. Therefore, many vineyard owners refuse to use this insecticide

in addition to using pesticides, there is another method with less side effects for growers to choose, that is, mounding

before the grape root driller larvae grow up, they must drill to the surface of the soil. In order to adapt to underground life, the larvae grow a thick cocoon. When the larva grows up and rushes out of the ground, the cocoon will fall off automatically

building mounds at the root of wine grapes means that it takes more time for the larvae to reach the ground. In this process, the larvae may have fully grown up. Without the protection of cocoons, the adults cannot return to the ground alive

however, it is a waste of manpower, time and financial resources to carry out the soil pile project in the whole vineyard, Sanders said. Sanders studied under the guidance of Oscar Liburd and is currently a professor of pest control at the UF food and Agricultural Science Institute

sanders said that long before he began to study pests, he had the honor to listen to a speech by Richard mank, an insect physiologist of USDA Agricultural Research Service Center, who will be held accountable. In his speech, Mankin described the scientists' understanding of an accelerator that can convert vibration into electronic signals, and then convert electronic signals into sound

mankin has used this equipment to detect whether there are pests damaging crops underground

Sanders said that the topic of his graduation thesis was to eliminate the larvae of grape root drillers before they grew up and were unearthed. At this time, he thought of Mankin's lecture

"it seems like a good idea - if they can use sound to find dinosaur bones and beetles, maybe they can use sound to find grape root drillers for me," he said

as a member of UF School of food and Agricultural Sciences, Mankin has assisted Sanders in the research project. Sanders, Mankin, Liburd, and Lukasz stelinski wrote scientific papers together

sanders said that it is not difficult to distinguish the sounds of underground insects and other noises, but it is difficult to distinguish the sounds of grape root drillers from those of other insects

after monitoring more than 30 grape roots in the commercial vineyards in florahome and lithia, Fla., researchers captured many insects, but only one grape root driller

however, Sanders said that the acoustic test was successful because the planter could use the instrument to eliminate the vineyard area that needs to be piled with soil

According to Mankin, he believes that the research on grape root drillers will eventually help 22 wineries in the state. He also expressed his hope that Sanders would ensure sufficient funds for the operation of the project and invest more time for the research

"I think this method is feasible," Mankin said. "The grape root driller is a big problem for the local wine grape growers."
