A method for trapping and killing adults of Monochamus alternatus with high efficiency and its special device

Abstract

The invention discloses a method for efficiently trapping Monochamus alternatus and a special device for the method. According to the method, traps are installed in a Monochamus alternatus region, and the Monochamus alternatusis trapped by 495-500nm of light waves emitted from the traps. According to the method for efficiently trapping the Monochamus alternatus and the special device for the method, disclosed by the invention, the Monochamus alternatus is trapped by adopting monochromatic LED (light-emitting diode) illuminators, so the trapping efficiency is high; the method has a very good trapping effect on the Monochamus alternatus in a diet supplement period and a spawning period, not only is capable of reducing the population number of the Monochamus alternatus and monitoring the population dynamics of the Monochamus alternatus but also is suitable for preventing the propagation of Bursaphelenchus xylophilus to reduce the hazard of the Bursaphelenchus xylophilus.

Description

technical field [0001] The invention relates to monitoring and pollution-free control technology of harmful forest organisms, in particular to a method for efficiently trapping and killing adults of Monochamus alternata and a special device thereof. Background technique [0002] Monochamus alternatus ( Monochamus alternatus ) is an important borer pest of coniferous trees in my country, which can harm pines such as black pine, masson pine, red pine, Yunnan pine, loblolly pine, etc.; it can also harm coniferous trees such as spruce, larch, fir, and cedar. At the same time, it is also a devastating disease of pine trees - pine wood nematode ( Bursaphelenchus Xylophilus ) are the main vectors of insects. In the process of the spread and infection of pine xylophilus, Monochamus alternata plays a key role in carrying, spreading and assisting the pathogen to invade the host. Adult pine beetles carry a large number of pine wood nematodes after eclosion out of the hole. Choose h...

Problems solved by technology

[0003] At present, the traditional chemical control method is still used in my country to kill the adults of Monochamus alternatus, which is not only costly and ineffective, but also brings serious negative effects, such as killing natural enemies, environmental pollution and drug resistance.

In recent years, although the research on the use of biological control methods to control Monochamus alternatus has continued to deepen and develop, but due to the constraints of environmental factors and the specificity of biological agents, the control effect is not obvious
