About This Product
■Product features
The Kubiaka Guard Net is a net designed to prevent the intrusion, spawning, and escape of the "Kubiaka Tsuyaka", which is a natural enemy of rose family trees such as cherry blossoms, peaches, and plums.
■Ecology of the long-eared longhorn beetle
・Habitat: Widely distributed in southern Russia, Mongolia, China, and the Korean Peninsula, and has invaded Japan as an invasive species.
・Body length/color: The adult body length is approximately 2.5 to 4 cm, the entire body is black and shiny, and the thorax (pronotum) is red.
*Males have longer antennae than females (about twice the body length)
■Early detection measures are essential
A large amount of frass eaten by the larvae is excreted at the base of the damaged tree, so if you find it, take early measures. We recommend installing a black-and-white guard net to prevent the seeds from scattering from damaged trees and from laying eggs on undamaged trees in the surrounding area. The black-necked beetle has a strong reproductive capacity, and there are concerns that the damage will expand in the future. Since they are diurnal and active during the day, damage can be reduced by catching and killing them immediately when spotted.
■Basic construction methods for tree protection
・Straight wrapping specification: Installation method when wrapping around trees with no branches
・Multiple main branches connected wrapping specification: Installation method when wrapping around trees with multiple main branches
*When winding the net, in order to prevent spawning from the outside and chewing from the inside, please float the net so that it does not come into close contact with the tree as much as possible.
