Embodiment Construction

[0016] 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 not more than 1% to each of the prepared attractants, then take 15ml of attractants and inject them into slow-release bottles, add attractants once every 15 to 20 days, and put 50 ml of attractants into each trap. bottle. 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...

Abstract

The invention relates to a monochamus alternatus imago attractant which belongs to the technical field of pest control. The monochamus alternatus imago attractant contains the following components according to volume percent: 60-80 percent of turpentine oil, 16-24 percent of ethanol, 2-10 percent of phenethyl alcohol and 2-6 percent of terpilenol. The monochamus alternatus imago attractant contains the following ingredients according to volume percent: 24.64-32.86 percent of Alpha-pinene, 22.91-30.55 percent of Beta-pinene, 6.51-8.68 percent of 3-carene, 2.97-3.96 percent of Beta-phellandrene, 0.74-0.99 percent of terpinolene, 0.62-0.83 percent of laurene, 1.60-2.13 percent of others, 16-24 percent of ethanol, 2-10 percent of phenethyl alcohol and 2-6 percent of terpilenol. The monochamus alternatus imago attractant has remarkable attracting effect to both monochamus alternatus female worms and male worms, and stronger attracting effect to the male worms; and also has certain attracting effect to other coleopteran forestry pests. The invention has the advantages of high efficiency, environmental protection, simple and convenient preparation, low cost and good durability, can be used for prediction and control in monochamus alternatus forest with the control effect up to 53.59-67.30 percent and can effectively control the population density in the monochamus alternatus forest and restrains the spread and the extension of pine wood nematode disease.

Description

Technical field: [0001] The invention relates to an adult attractant for Monochamus alternatus Hope, which belongs 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 harm is the spread of pine wood nematode. Pine wood nematode (Bursaphe lenchus xylophilus) is a global invasive alien organism, and is currently an internationally recognized quarantine object. It is one of the m...
