Comprehensive treatment method for preventing pine wood nematode disease from spreading

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...
