experiment example 1

[0073] In Yeongcheon, Gyeongsangbuk-do, a pine cluster site with dead trees or dead trees was selected, traps were set on March 29, 2014, and the survey was carried out until May 3. 2 traps are used.

[0074] As a trap, 6 continuous funnel traps are used. As a carrier, considering the molecular characteristics, release speed and stability of the Beetle pheromone, the outside is made of TPU material, and the inside is put in a PE tube. The assembly pheromone is filled in the PE tube, and α-pinene and ethanol are directly loaded into the TPU material. A composition comprising 50 mg of 2-(undecyloxy)-1-ethanol, 20 ml of α-pinene, and 20 ml of ethanol was used as the attractant composition.

[0075] Its result is as shown in table 1 below, and the beetle photo captured in the bucket is as follows Figure 4 shown.

[0076] [Table 1]

[0077]

experiment example 2

[0079] In Pohang, Gyeongsangbuk-do, a pine tree cluster site with dead trees or dead trees was selected, traps were set on May 25, and the survey was carried out until June 8. A total of 10 traps were used.

[0080] The traps and carriers used were the same as in Experimental Example 1. As an attractant composition, a composition consisting of 100 mg of 2-(undecyloxy)-1-ethanol, 40 ml of α-pinene, and 40 ml of ethanol was used on five traps, and a composition consisting of 2 - Compositions consisting of 200 mg of (undecyloxy)-1-ethanol, 80 ml of α-pinene, and 80 ml of ethanol were each contained twice or four times the composition of Experimental Example 1.

[0081] Its result is as shown in table 2 below, and the beetle photo that captures in the barrel is as follows Figure 5 shown.

[0082] [Table 2]

[0083]

experiment example 3

[0085] In Gyeongju, Gyeongsangbuk-do, a pine tree cluster site with dead trees or dead trees was selected, traps were set on June 26, and the investigation has continued until now. A total of 6 traps were used.

[0086] The traps and carriers used were the same as in Experimental Example 1. As the attractant composition, a composition composed of 10 mg of 2-(undecyloxy)-1-ethanol, 5 ml of α-pinene, and 5 ml of ethanol was used on No. 1 and No. 2 traps, A composition composed of 100 mg of 2-(undecyloxy)-1-ethanol, 25 ml of α-pinene and 25 ml of ethanol was used on traps, and 2-(undecyloxy)-1 -A composition consisting of 1000 mg of ethanol, 250 ml of α-pinene, and 250 ml of ethanol.

[0087] Its result is as shown in table 3 below, and the beetle photo that catches in the bucket is as follows Figure 6 shown.

Abstract

The present invention relates to a method for controlling pine wood nematode by installing, at regular intervals, net type traps including an attractant composition for attracting Monochamus alternatus and Monochamus saltuarius, which are pollinating insects of pine wood nematode, and capturing, within the traps, the attracted Monochamus alternatus and Monochamus saltuarius. The present invention can constantly and effectively capture Monochamus alternatus and Monochamus saltuarius over a whole generation by forming a net-type trap system at a control area on the basis of the physiological, ecological, and behavioral characteristics of Monochamus alternatus and Monochamus saltuarius which do not show active scattering mobility, and thus can control the damage caused by pine wood nematode through the medium of Monochamus alternatus and Monochamus saltuarius and can forecast whether or not damage will occur.

Description

technical field [0001] The invention relates to the prevention and treatment of pine wood nematode disease, especially the prevention and control method of pine wood nematode disease realized by predicting and capturing the vector insects of pine wood nematode disease monochamus and monochamus spruce. Background technique [0002] Pine wood nematode (Bursaphelenchus xylophilus) is a pest that causes pine wilt disease (Pine Wilt Disease) to pine trees, maritime pine, fruit pine, and the like. Pine wood nematode disease is also called pine tree AIDS. Because pine wood nematode invades pine trees, the leaves of the infected grove will droop after 6 days, and the leaves will wither from the 20th day. After 30 days, it will turn red sharply and 100% will die. Is a fatal disease (http: / / www.kfri.go.kr / Korea National Academy of Forestry). [0003] Pine xylophilus is a soil species in the North American continent (Knowles et al., 1983; Dwinell, 1993), and most of the native tree sp...
