There are no geographical boundaries to the damage caused by the “Kubiaka” that eats away at cherry trees. As a first step to passing on beautiful cherry blossom trees to the next generation, Japan Wide Cross begins crowdfunding for the cost of installing insect repellent nets.
*Crowdfunding started on CAMPFIRE to protect cherry blossoms from damage from foreign pests*

On May 8, 2024, Kotobuki started crowdfunding on CAMPFIRE for the cost of applying measures to control foreign pests to cherry trees. In the spring of 2024, many people came not only from Japan but also from abroad to see the cherry blossoms in full bloom all over the country. on the other hand,*
Japan’s cherry blossoms are under threat as the habitat of the specified alien species, the “Kubiakatsuyakamiki” (commonly known as the “Kubiaka”), which devours the insides of cherry blossoms, is expanding year by year. *
Its habitat extends from Russia to Vietnam, and even from Hokkaido to Okinawa according to the map of Japan, and trees in the Rosaceae family, such as cherry blossoms and peaches, are being eaten, and many trees are dying. This is a critical situation.
However, local governments that manage cherry blossoms often do not have sufficient budgets for cherry blossom conservation, and it is currently difficult to spend money on countermeasures against yellowtail mosquitoes.
Therefore, with the desire to pass on the beautiful rows of cherry blossom trees, which are a symbol of Japan’s spring landscape, to the next generation, we decided to install our company’s product “Kubiaka Guard Net (R)” to prevent the damage caused by Kubiaka. In order to protect the cherry blossoms in the Tatsuta Kodo Satoyama Park in Kashiwara City, Osaka Prefecture, we decided to conduct crowdfunding with the cooperation of Kashiwara City. We would like to receive the support and cooperation of as many people as possible, and together we can take the first step toward ensuring that Japan’s cherry blossoms continue to bloom forever.

■Crowdfunding support message from Kashiwara Mayor Masahiro Tomitake Regarding the implementation of this project, we received a message of support from the Mayor of Kashiwara, Masahiro Tomiya.

We want to protect Japanese cherry blossoms from damage from the foreign pest “Kubiaka”! Message to the project

We are very grateful to Nippon Wide Cross Co., Ltd. for implementing this project to protect cherry blossoms in Kashiwara City.
In recent years, damage to cherry blossoms and other plants caused by the Japanese longhorn beetle has been increasing in Kashiwara City, and the city is struggling to find countermeasures.
By implementing this project, we hope that as many cherry blossom trees as possible in Tatsuta Kodo Satoyama Park will be protected, and that many people will enjoy the park as one of Kashiwara City’s famous cherry blossom viewing spots. Thank you very much for your support!

■Future outlook
Damage caused by Kubiaka is increasing nationwide, but many local governments are unable to secure sufficient budget for
countermeasures. Starting with Kashiwara City, where Japan Wide Cross Co., Ltd.’s head office is located, we would like to work with local governments across the country to carry out a project to protect Japan’s cherry blossoms.

■What is the black beetle?
Place of origin: China, Korean Peninsula, Vietnam, etc.
Body length: 2.5-4cm
Characteristics: Adults are glossy black overall with red thorax (neck area) Ecology: The larvae devour a wide area under the bark, excreting frass (wood chips and droppings), and live for 2 to 3 years before becoming an adult. Compared to other longhorn beetles, they have an extremely high reproductive capacity, and if countermeasures are not taken late, there is a risk of large numbers of insects occurring, and they are classified as “Specified Alien Species (those that cause damage to ecosystems, human life and bodies, and agriculture, forestry, and fisheries industries).” has been designated and is subject to pest control.

■Damage situation and countermeasures caused by Kubiaka

Trees infested with Kubiaka become weakened and die as the inside of the tree is eaten away by the larvae. In addition to the risk of human injury due to falling branches and fallen trees, damage is also spreading to cherry trees and agricultural crops (peaches, plums, etc.). In some areas, rows of cherry blossom trees that have long been beloved by locals have been cut down, with the tree trunks being eaten away by the yellowtail, which is having a serious impact on the growth and beauty of cherry blossoms.
Current countermeasures are mainly centered around cutting down damaged trees and controlling larvae and adults using chemicals, but experts say that it is still inconclusive and that a combination of physical control is essential. I am. As for physical “net control,” net covering has the same effect as a so-called influenza prevention mask, and prevents the insects that have been laid and grown into adults from escaping, thereby preventing the spread of damage. This has been widely implemented to prevent new spawning and damage. However, there were problems at the time, such as eggs being laid between the mesh, being bitten off by adults, and difficulty seeing inside. Therefore, in order to solve these problems, we have newly developed “Kubiaka Guard Net (R)”, which is used for cherry blossom trees, peaches, and plum trees, which have many main branches and are difficult to wrap with nets. Measures can now be taken for fruit trees such as

* ■What is Kubiaka Guard Net*
“Net control” is one of the measures against black-eye mosquitoes. Net covering has the same effect as a so-called influenza prevention mask, and prevents the eggs that have been laid and grown into adults from escaping, thereby preventing the spread of damage. This has been widely implemented to prevent new spawning and damage. The “Kubiaka Guard Net (R)” developed by our company is a net that prevents intrusion and spawning escape exclusively for the Kubiakatuya long beetles.
* Feature 1. Hard to get chewed up *
…This product was designed with a mesh size of 0.4mm after researching the ecology of the black-spotted duck and through trial and error. A net with a mesh size of 0.4 mm will not allow the ovipositor of the blacktail mosquito to pass through, and adults will not be able to bite through the net easily if the mesh is narrow. Additionally, this 0.4mm insect repellent net has been used for over 15 years to control whiteflies, thrips, and oak beetles in parks where pesticides cannot be used.
* Feature 2. Easy to see inside the internet *
…Adult insects and frass can be easily confirmed from outside the net, allowing for chemical injection treatment and adult trapping without missing the timing. In addition, black is easy to blend into the landscape and matches trees.
* ■What we want to achieve with crowdfunding*
In order to protect the cherry blossom trees in Satoyama Park on Tatsuta Kodo, Kashiwara City, the funds donated by everyone will be used to pay for the construction of the Kubiaka Guard Net.
* -About recruitment method-*
