Embodiment 1

[0028] Turpentine, ethanol, phenylethyl alcohol, and terpineol were formulated into attractants A, B, C, D, and E according to the ratios shown in Table 1. Add Tween-80 surfactant with a content of no more than 1% to each prepared attractant, and then inject 15ml of attractant into the slow-release bottle, add attractant once every 15-20 days, and put each trap into 5 bottles. The traps are set in an open and ventilated place in the forest, hung on the wire between two trees, the lower end is 2-3m above the ground, and the distance between each trap is more than 50m. Record the number of female and male adults of Monochamus alternatus trapped and the types and quantities of other forestry pests every 2 days, and dissect and microscopically check whether each adult Monochamus alternata is carrying B. xylophilus. The attractant was replaced every 20d. Each treatment was repeated 5 times. Continue to investigate the whole activity period of Monochamus alternatus adults. The t...

Embodiment 2

[0041] The adult monochamus alternatus trapper of the present invention comprises cylindrical main body (3), funnel-shaped insect catcher (6), and insect catcher (6) lower end is connected with collecting insect bottle (7), wherein:

[0042] a. The upper end of the brown cylindrical body (3) is provided with a detachable cover (2), and 20 or 30 attractant distribution holes (4) with a diameter of 2 or 3mm are symmetrically opened on the outer surface, and welded on the outer surface. Three brown insect-retaining wing plates (5) that form 120° each other, each of the top ends of the wing plates (5) is bolted with an iron wire and integrated into a bundle to become a hook (1), and the lower ends of the wing plates (5) are riveted on the insect-receiving hooks (1) with screws. On the device (6), the fin plate (5) is 5 or 10cm longer than the main body (3);

[0043] b. the upper opening diameter of the insect catcher (6) with smooth inner wall is 8 or 12cm larger than the diameter...

Abstract

The invention relates to a monochamus alternatus imago attractant and a trap thereof, which belong to the technical field of pest control. The volume percents of the components of the attractant are 60 to 80 percent of oil of turpentine, 16 to 24 percent of alcohol, 2 to 10 percent of phenethyl alcohol and 2 to 6 percent of terpineol. The volume percents of each component of the attractant are 24.64 to 32.86 percent of alpha-pinene, 22.91 to 30.55 percent of beta-pinene, 6.51 to 8.68 percent of 3-carene, 2.97 to 3.96 percent of beta-phellandrene, 0.74 to 0.99 percent of terpinolene, 0.62 to 0.83 percent of laurene, others for 1.60 to 2.13 percent, 16 to 24 percent of alcohol, 2 to 10 percent of phenethyl alcohol and 2 to 6 percent of terpineol. The trap consists of a cylindrical body (3), a funnel-shaped imago picking device (6) arranged at the lower part of the body (3), and an imago collecting bottle (7) connected with the lower end of the funnel-shaped imago picking device (6). The attractant has the advantages of convenient preparation, simple usage and long lasting period, and is a nuisanceless plant protection product; and the trap has the advantages of simple structure, low cost, long service life and good attracting effect, and can be wildly applied to the monochamus alternatus imago control in the field.

Description

Technical field: [0001] The invention relates to an adult attractant for Monochamus alternatus Hope and a trapping device thereof, belonging to the technical field of pest control. Background technique: [0002] Monochamus alternatus, also known as monochamus alternatus, is an important borer pest on pine trees. The direct damage caused to pine trees by the pine monochamus is that its larvae harm the phloem and xylem of weak pine trees and pine trees that are on the verge of weakening, destroy and cut off the transporting tissue, affect the transportation of water and nutrients, and affect the growth of pine trees, resulting in pine tree flakes. and die; adults form wounds on young shoots of healthy pine trees during the nutritional supplementation period, causing them to die. The indirect hazard is the spread of pine wood nematode. Pine wood nematode (Bursaphelenchus xylophilus) is a global invasive alien organism, and it is currently an internationally recognized quarant...
