Among them, the average annual diffusion distance before 2008 was about 4 kilometers. In the past five years, it has shown a momentum of accelerated diffusion, with an average annual diffusion distance of 8 kilometers. If this momentum is not effectively controlled, it will make Guangdong 50 million mu Pine forests have suffered extinction, causing huge economic losses, and immeasurable potential ecological disasters

Embodiment 1

[0052] From 1998 to 2000, the comprehensive control of pine wood nematode at the national level was settled in Guangdong, and Huizhou was the main implementation base. At that time, the overall goal of the project management was to control the occurrence range of pine wood nematode to the south of Guangshan Highway, which was a relatively macroscopic and thick line. In order to explore the mechanism of controlling the non-spread of the epidemic, we carried out research on the non-spread of the epidemic in the 3000 mu 25-year-old Pinus massoniana pine wood nematode occurrence area in Shanding Village, Zhenlong Town, Huiyang District. Firstly, use the 1 / 10,000 topographic map to mark the boundaries between forestry subcompartments where pine wood nematode occurs and non-occurrence forestry subcompartments on the map, count the test area, and formulate technical plans. Through measures such as timely clearing dead wood of pine wood nematode disease in time and space for three yea...

Embodiment 2

[0054] From 2002 to 2008, comprehensive management was carried out in 1800 mu of masson pine in Xishan Village, Xinmin Town, Tongan District, Xiamen City. By timely clearing dead wood of pine xylophilus disease and removing the breeding materials of monochamus larvae, including selective cutting, thinning of weakened wood, repairing dead side branches, etc., with the health of pine trees and the health of forests as the overall management goal, Finally, the two discrete masson pine forests in Daxi Mountain and Xiaoxi Mountain are only separated by the 324 National Highway, and the distance between the two forest edges is only about 200 meters, achieving the governance goal of controlling the spread of the epidemic for seven consecutive years.

Embodiment 3

[0056] Liuxihe Forest Farm in Guangzhou City discovered pine wood nematode disease in 2006. At that time, the occurrence range was 1302 mu. By 2008, the occurrence range had increased to 13000 mu. The occurrence range had increased by 10 times in just three years. Liuxihe Forest Farm The existing forest area is 100,000 mu, of which the pine forest area (including mixed forest) is 38,000 mu, and the rest of the secondary broad-leaved forests are scattered with masson pine. Since 2009, through the timely cleaning of all monochamus alternatus larval breeding materials, the traps for monochamus monochamus are hung and loosened from April to June every year, and the traps are hung within a range of 200-250 meters within the boundary. An average of 50 acres of monochamus positioning type, and its spawning type traps are hung, and the lure wood is set up in May and July every year to collect the adult beetles to lay eggs, and the lure wood is cleaned in July and October respectively. ...

Abstract

The invention relates to the field of comprehensive treatment of serious pests in China. A comprehensive treatment method for preventing a pine wood nematode disease from spreading comprises the steps that a borderline between a pine wood nematode disease outbreak area and a non-outbreak area forestry subcompartment is partitioned by adopting a continuous forestry subcompartment as a unit; all larval monochamus alternatus breeding materials in the pine wood nematode disease outbreak area are cleaned spatially and continuously; monochamus alternatus trapping devices are hung and placed in an eclosion peak period of adult monochamus alternatus every year; one trapping device is hung and placed for every 40-60 mu; one trapping tree is placed at every 50-100 mu averagely for trapping the adult monochamus alternatus to lay eggs after all the larval monochamus alternatus breeding materials in the pine wood nematode disease outbreak area are cleaned; and the trapping trees are cleaned after the adult monochamus alternatus is trapped to lay the eggs. According to the comprehensive treatment method, the population density of the monochamus alternatus is controlled bellow one per five mu, and the purpose of preventing the pine wood nematode disease from spreading is achieved.

Description

technical field [0001] The invention relates to the field of comprehensive management of major harmful organisms in my country, and specifically relates to comprehensive technical measures for controlling the natural spread of pine wood nematode, the most serious biological disaster in my country's history. Background technique [0002] Pine is an irreplaceable rural tree species for land afforestation and ecological environment construction in my country. my country's 500 million mu of pine forest resources is not only a barrier for ecological security, but also a strong material basis for building a well-off society in rural areas. Pine wood nematode is a devastating disease of pine trees. Due to the devastating hazards of pine wood nematode, the difficulty of control, the multiple transmission routes and the wide range of suitable habitats, more than 40 countries and regions in the world have listed it as a quarantine object. Since the discovery of pine wood nematode di...
