How to control the Monochamus alternatus?

The Monochamus alternatus is an insect of the genus Monochamus of the genus Monochamus, an important pest of the Chinese pine tree, and also a devastating disease of pine trees. It is the major vector insect of the pine wood nematode disease, and it spreads and infects the pine wood nematode. In the process, it plays a key role in carrying, spreading, and assisting pathogens invading the host. Let's take a look at how to deal with it.
From October to April of the previous year (the pupa and adult stages)

1. Concentrate the damaged logs and pine rods, cover them with plastic film, place the fumigant evenly around the membrane, and quickly press the edges of the membrane with soil to seal it. Usually fumigation can take 2 to 3 days.

2. Steam heat, hot curing in chamber or heat treatment at constant temperature of 50°C for 24 hours. Pesticide wood fumigation and fumigation treatment must be performed before adult fly, aluminum phosphide 4g/m3, methyl bromide 16g/m3 Or sulfuryl fluoride.

3. Adjust the harvesting period to the end of autumn, and adjust the sales period to winter and spring so that all the pine rods under harvesting can be sold before the endangering of Tianniu, thus avoiding the occurrence of man-made insects.

In April and December, cleaning insect pest wood, weak wood, pressed wood and undergrowth shrubs, weeds, etc. can reduce the population density of pine brown beetle between forests.

5. The use of natural geographical conditions to open up a 4 km wide isolation zone can effectively prevent the spread of Monochamus alternatus.

6. Insect pests are stored outside the forest for 12 months after being felled. Newly cut pests are cut into planks with a thickness of 2 cm or less, which kills most of the brown monstrous cattle.
May to August (Yangfei adult stage)

1. Set bait traps and traps. The decoy wood is separated by more than 100 meters. Each point is cut 1 live pine tree, divided into 3 sections and stacked into a triangle frame. The branches are stacked under a tripod and a new section is added to the tripod at a certain interval. Tree sections.

2. The traps in the forest can be monitored for their occurrence and population changes. The impact of the hitting plate funnel or the hitting plate basin trap is best. The attractant is arranged in a 33 grid shape. 450-watt high-pressure mercury lamp was used to trap and kill Monochamus alternatus.

3. Spray 50% of acaricloside or 25% diflubenzuron III suspension 1000 to 1500 times, and use mid-April and mid-May use 50% 100% of buprofezin and buprofezin in mid-May. In the middle of June, spray twice 400 to 500 times Baosongling, in the middle and late June, ultra-low volume spray 8% green Weilai 900 ml/ha, and in the brown horn beetle nutritional period 12% fenthion EC 150 times +4 % polyvinyl alcohol 100 times + 2.5% deltamethrin EC 2000 times spray control.
May to September (eggs, larvae, and pupa)

In January and July, it was used to release the tuber swollen leg bee at a density of 0.5 million heads per hectare.

2, in the fall with a gauze bag of Beauveria bass powder or invasive hole injection of bacteria.

3, indoor breeding Huarong Ken Jia Lin release.

4, pay attention to protect tuber swollen leg bee, Beauveria bassiana and attract natural enemies such as woodpeckers.

5. Strictly strengthen quarantine and prohibit the transport of insect-infested wood and wooden packaging without any treatment. Once discovered, it will be destroyed on the spot.
