Ryukyu University: Give vibration to reduce pests: Effective with tomatoes,
Ryukyu University and Forestry Research Institute:
The research team announced on December 30th.
Expected to reduce pesticides By giving small vibrations to seedlings, it was confirmed that the effect of reducing pests on tomatoes was confirmed.
Reduce pesticide application:
It is thought that the stress caused by vibration causes pests to escape or stop mating.
Ryukyu University:
Professor Haruki Tateda pointed out that “if used properly, the amount of pesticide sprayed can be reduced.”
Three years later, we aim to put the device into practical use.
Bemisia tabaci:
The pest is a tobacco whitefly with a body length of about 1 mm.
Absorb nutrients from tomato leaves,
Spread the virus that kills plants,
A type that is resistant to pesticides has appeared
Countermeasures have become an issue.

Developed a new method for controlling Bemisia tabaci by vibration
Forestry Research Institute, Ryukyu University:
Bemisia tabaci:
Bemisia tabaci is an important agricultural pest that damages various vegetables such as tomatoes, foliage plants, and flowers, and exhibits drug resistance to most chemical pesticides.
Therefore, a new control technology that does not rely solely on chemical pesticides has been sought.
New control technology:
The research group has focused on the sensitivity of insects to vibration and has been conducting research so far.
Insect vibration sensitivity:
As a result, the densities of adults and larvae in the vibrated plot decreased compared to those in the non-vibrated plot.
Especially in the case of larvae, it was confirmed that a 40% decrease was confirmed in the vibrated group compared to the non-vibrated group.
From this, it was clarified that the population of Bemisia tabaci on the plant can be reduced by giving vibration to the plant body.

Substrate-borne vibrations reduced the density of tobacco whitefly Bemisia tabaci (Hemiptera: Aleyrodidae) infestations on tomato,
Solanum lycopersicum : an experimental assessment
Abstract
We aimed to examine
whether substrate-borne vibrations effectively drive away tobacco whiteflies [Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae)], which are serious agricultural pests.
To do so, B. tabaci individualswere artificially introduced into greenhouses where tomato (Solanum lycopersicum L.) plants were reared.
A substantial reduction in the average density of B. tabaci nymphs and adults was achieved by transmitting vibrational stimuli to the plants.
At the same time, no obvious reduction was found in the number of tomato plant flowers.
Although the performance of the vibrational device and transmission
procedures requires further improvement, the present results shed light on the potential of substrate-borne vibrations as a promising alternative for pest management.
