Broad-spectrum attractant for bark beetles as well as preparation method and application of broad-spectrum attractant

Abstract

The invention relates to the field of biological attractants, in particular to a broad-spectrum attractant for bark beetles as well as a preparation method and application of the broad-spectrum attractant. The broad-spectrum attractant for the bark beetles comprises Ipsdienol (Id), (S)-cis-verbenol (cV), exo-Brevicomin (xB), ethanol (E) and alpha-pinene (P), has a very strong trapping effect on multiple Genuses of insect adults in the bark beetles, is low in cost and high in broad-spectrum property, can play a role in efficiently trapping multiple bark beetles in different working environments at the same time, wherein pheromones of part of the trapped small beetles are even not clear. Meanwhile, the attractant has a relatively strong attraction effect on multiple insects such as longhorn beetles, weevils and paillettes, so that the attractant is more beneficial to popularization and application.

Description

technical field [0001] The invention relates to the field of biological attractants, in particular to a bark beetle broad-spectrum attractant and its preparation method and application. Background technique [0002] Bark beetle is the general term for insects of Hexapoda, Insecta, Coleoptera, and Scolytidae. It is a small beetle with a body length of about 0.8mm-9.0mm, generally oblong Shaped or cylindrical, and a few are hemispherical, it is one of the world's major forest pests that harm forests. So far, more than 6,000 species of about 220 genera have been recorded. At present, more than 500 species have been recorded in my country, of which more than 120 commonly occur. kind. Common pests are Ipsspp., Dendroctonus spp., Xyleborus spp., Hypothenemus spp., Pityogenes spp.) etc. [0003] Bark beetles are small in size and cause damage inside trees or wood, so it is difficult to detect and attract attention, but they occur in a wide range of areas, as long as they are fores...

Problems solved by technology

[0005] In environments such as forests and imported timber yards, many kinds of bark beetles often appear at the same time. It is necessary to monitor and control a variety of bark beetles at the same time. High-efficiency broad-spectrum bark beetle attractants are necessary for work, and it is necessary to ensure that the substances used are of high quality. Biologically active, non-polluting, does not kill natural enemies, does not make pests resistant, but there is no product with broad-spectrum attractant for bark beetles on the market

At the same time, although the attractants are also mentioned in the prior art such as CN106614751A, CN106614578A, and CN106614575A, they belong to the genus-level attractants for the genus Leptospermia, the genus Dendrobetrix and the genus Beetle respectively in turn, and do not have the broad-spectrum
