Description
Technical Field
The invention relates to the technical field of forestry pest control, and particularly relates to a longicorn repellent and a preparation method thereof.
Background
The longicorn is an important trunk-boring pest of pine trees in China and also a main vector insect of pine trees for destroying and preventing pine wood nematode diseases, and plays a key role in carrying, spreading and assisting pathogen to invade host in the process of diffusion and infection of the pine wood nematode. Adult longicorn is a medium for spreading nematodes, and the body surface of the adult longicorn is attached to nematodes after the adult longicorn goes out of xylem, but most of the nematodes are in the body and can be distributed in the whole tracheal system in the form of the largest head and chest, the number of the nematodes can be kept to 289000 at most by 1 head of the adult longicorn, the nematodes are separated from the longicorn in 2-3 weeks after the adult longicorn goes out, the separation rate is about 43-70%, the separated nematodes can invade trunks to be damaged, and meanwhile, the difficulty in preventing and controlling longicorn and pine nematodes carried and spread by the longicorn is high due to the irregular generation of the longicorn.
Although the chemical prevention and control means of the insecticide can achieve temporary killing effect, the chemical prevention and control means of the insecticide can easily cause drug resistance of pests, cause pesticide residue to pollute the environment and harm other beneficial organisms when the chemical prevention and control means is improperly used, and have increasingly prominent negative effects. With the continuous improvement of life and environmental quality, the demand of the insect repellent is continuously increased, and although the insect repellent cannot poison pests, the insect repellent has special smell which can enable the pests to escape or repel the pests. However, the existing longicorn repellent has the problems of chemical residue and short repellent effect.
