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.
