In Xiao Wu's hometown of Hunan Xinhua rural mountains, there are many wild fir trees, these fir trees used to be used to build houses, make furniture, but in recent years, rural houses have also used cement and steel bars, the status of this fir tree is getting lower and lower, and the fir trees that grow on the mountain are not of much use. There are only those who collect wood to collect it to make a template.
These wild fir trees, are decades old, up to more than 10 meters high, most of them grow straight, at the end of last year, Xiao Wu returned to his hometown once, and saw the pine needle leaves on the trees, full of emerald green, very beautiful. Unexpectedly, when I went home in May to plant fields, I saw that the leaves of the fir trees on the mountain were bare, and my father said that it was eaten by caterpillars. It's terrifying.
Let's see the fir forest that has been eaten by caterpillars has become this look, the emerald green of the past has become like this, the fir tree is also the masson pine, the fir tree is the name of Xiao Wu's hometown, this caterpillar, also called pine caterpillar, caterpillar. It is a genus of caterpillars in the family Lepidoptera leaf moths, and caterpillars are one of the most important pests on masson pine trees, and are eaten almost every few years in Xiao Wu's hometown. Once this caterpillar occurs, it is very violent, and the large fir forest is quickly eaten by them, and if people walk into the fir forest, they can clearly hear the sound of caterpillars eating pine needles, and the noise is noisy, and it is creepy to listen to. If a large area is eaten by caterpillars, in just a few days, the needles will be eaten, and from a distance, it will look like a yellow or scorched black, which is like a fire, often compared to a "smokeless forest fire".
Fir trees that have been eaten by caterpillars will affect growth at the light, and cause the death of fir trees in pieces, and cause the invasion of dried insect pests such as pine moths and pine pit cut-out beetles, causing secondary disasters. This caterpillar mainly harms Masson pine, black pine, Huangshan pine, wetland pine, torch pine and other pine plants. Caterpillars not only cause fir trees to die, but at the same time, the fields, fields, rivers, and even homes are full of insects, affecting people's normal lives.
Once the fir forest is stuck with caterpillars, the peasant friends have no way at all, and can only watch the insects eat, because the fir trees are more than 10 meters high, and the farmers cannot hit the medicine, and manual capture is impractical. Often at this time, you can only turn to the forestry department and arrange unmanned aircraft to spray medicine.
Friends, is there such a masson pine tree in your hometown? Have you ever had this caterpillar grown there, and how did you control it? Everyone is welcome to leave a comment below. Thank you.
