There is a big tree in front of the residence
Block the sun from blowing wind
The wind blows the leaves and brings up a "rustling" sound
It's heart-warming to listen to
Of course
Trees are not only windy, but also insecticidal
Homeland Jun received a message saying
A big tree in a cotton community
Recently, there have been black "strange butterflies"
Lie on the leaves in the morning
It was hot in the afternoon
Fly around
Nibble on the leaves
00:08
The residents of the community are very troubled
Afraid that it has bacteria, and afraid of hurting people
What exactly is a "strange butterfly"?
Will it hurt?
And what methods can be prevented?
And listen to the Homeland King to tell you in detail

Xiaobian found through the map reading software that this strange butterfly and the Chongyang Wood Brocade Moth look similar!
Chongyang wood spotted moth is distributed in East China, Central China, South China provinces, municipalities and autonomous regions, is an important pest of Chongyang wood, adult insects fly on the canopy of Chongyang wood or other plant bushes during the day, sucking supplementary nutrition. The eggs are laid on the back of the leaves, and the larvae feed on the leaves, and in severe cases, the leaves are eaten up, leaving only the leaf veins.
The picture shows the broken blades that have been eaten ↑↑
Recently, there have been several rains, the hot and humid environment is conducive to its large growth, and the larvae live in large groups and eat large amounts, which is very easy to cause serious harm to green trees. The adults of the Chongyang wood spotted moth do not bite, but their larvae are "caterpillars" and often spit silk from the trees. The larvae have spiny hairs that can lead to allergies and skin discomfort if a person accidentally touches it.
Face the pests
We are not helpless
Three control techniques
Hope that helps
Homeland Jun also hopes for this pest
Able to solve as soon as possible
Heavy Yang wood brocade moth control
01 Chemical control: during the larval stage, spray with 1.2% nicotinine emulsion 800-1000 times liquid, or 1% insecticide emulsion 2000-2500 times liquid spray, or Uranus and other permethrin insecticides.
02 Forestry technology control: the fourth generation of larvae coincide with the fallen leaves of Chongyang wood, and the insect body should be cleaned up in time with the leaves, and the dead branches and leaves should be cleaned up in time and burned in time to eliminate the overwintering insect state; the trunk of the tree before wintering is booby-trapped or whitewashed.
03 Biological control: rational protection and utilization of natural enemies, such as egg parasitic bees, velvet cocoon bees, etc.
