There are five ways to kill the beetle.

The larvae of beetles, commonly known as chicken dung insects, gnaw on the roots of seedlings, in addition to biting lateral roots and main roots, but also can peel off the root skin, resulting in lack of seedlings and broken strips, and in serious cases, it will also cause devastating disasters. Adult beetles like to eat both leaves and flowers, and the reproduction speed is very fast, which is easy to cause harm to seedlings, and is a common major pest in forestry. The time of rampant adult damage is about June to October, which is the best period of control, that is, to control the adult damage and the population density of the next generation, we will get twice the result with half the effort.

First, the artificial killing of beetles by artificial death has the characteristic of fake death. It often stays quietly on the tree and falls down as soon as it touches it, motionless, as if dead. Using this characteristic of its adult, we can capture it manually. For cases with high population density, more weeds or taller trees, you can wrap a layer of plastic sheeting under the tree, and then shake the tree vigorously, and it will automatically fall off and catch again. The captured adults can be smashed directly, this method is low in cost, and the effect is better, no drug pollution.

Second, the use of phototactic light to trap beetle adults has phototactic characteristics, in the forest glades or roads, roofs, set up a black light, and then configure a 3000 to 5000V

High-voltage power grid or equipped with a basin of water, a large number of adults will fly to the lamp at night and be electrocuted or drowned. Using this method to clean up dead insects every 1 to 2 days, in addition to killing beetles, it can also kill a large number of other phototaxis pests, achieving the effect of counting birds with one stone.

Third, using the characteristics of partial eclipse to lure and kill beetle adults have a preference for poplar, willow, and elm plants. When there is no wind at about 5 pm, we can use their branches and leaves to be stained with 80% trichlorfon 200 times liquid and put a bunch at intervals of 10 to 15 meters. Insert in the nursery or woodland to lure and kill, can well protect the target tree species and control the disaster.

Fourth, using the habit of going out at night to fumigate and kill beetles is to come out at night and feed. We can put insecticidal smoke on woodlands with proper canopy on a windless night, which will also achieve better results. Using this method, we must predict good weather changes in order to get better results.

Fifth, using chemicals to spray trichlorfon 1RV 800 to 1Rd 1000 times solution, 1.5% dimethoate powder, 25% trichlorfon powder, 40% dimethoate 800 times solution on branches, stems and leaves, scraping the trunk and then applying 40% omethoate solution 1 to 2 times, which has a good insecticidal effect on adults.
