Nearly 300 acres of Nan bamboo in Changde Hezhu Forest Park were infested with bamboo boat moths

The former verdant branches and leaves of nan bamboo have withered yellow and are covered with creepy "vegetable green worms". Yesterday, the reporter learned from the Changde Forestry Bureau that in late July, nearly 300 acres of Nan bamboo forest in Hehuan National Forest Park in Changde City were infested with bamboo boat moths.

Recently, the staff of Hehuan National Forest Park found that the bamboo forest was covered with "vegetable green insects", and the green silk that was spit out fell down, and what made people anxious was that many "vegetable green insects" were still wrapped in bamboo leaves. The staff realized it was a pest, but nothing was known exactly what it was. After receiving a call for help from the park staff, experts from the Changde Forestry Bureau confirmed after investigation that the pest was called the bamboo skeleton boat moth. Bamboo boat moth is one of the main pests of bamboo forests in the south, which is harmful to bamboo such as moso bamboo, rigid bamboo, light bamboo and so on.

In just a few days, the area of the insect-infested Nanzhu forest in Hehu National Forest Park is nearly 300 mu. According to the person in charge of the forest defense station of the Changde Forestry Bureau, the reason for the infestation of bamboo boat moths in Nanzhu in Hezhu National Forest Park is mainly because of the large density of insect populations, coupled with the continuous rainfall some time ago, the humid and hot climate is the "greenhouse" for the hatching of bamboo boat moth eggs. After hatching into larvae, they frantically eroded the bamboo forest until the weather was good and the staff found it, which had endangered a large area of the bamboo forest. "If you do not take advantage of the larval control, when the outbreak occurs, the new bamboo will die when it is damaged, and the bamboo will not be new for two or three years after the bamboo is damaged, and it will lead to the death of a piece." The bamboo boat moth in Hezhu National Forest Park has occurred for 2 generations this year, and the 3rd generation of larvae is about to be unearthed. ”

After on-site investigation, the Changde Forestry Bureau decided to adopt a combination of forestry measures, chemical control, and physical prevention and control to carry out prevention and control work. Prepare enough tobacco and potions to apply the cigarette agent when the 3rd generation larvae occur, and use black light to trap the adult bamboo boat moth. At the same time, when the bamboo forest is nurtured, the leaves and twigs of the bamboo forest are cleaned up in time, the insect cocoon is manually removed, and the source of insects is reduced; the rational logging is maintained to maintain the reasonable density of the bamboo forest and inhibit the occurrence of larvae.
