Problems solved by technology

However, as the resistance of storage pests increases and the problem of pest re-infestation becomes more serious, on the other hand, special storage products such as traditional Chinese medicinal materials and wine-making Daqu have higher requirements for pesticide residues, and traditional chemical control methods are not suitable for their control. storage pests

Embodiment 1

[0030] The Y-type olfactometer of embodiment 1 single-component attractant is measured

[0031] Under indoor conditions (25±2°C, 70±5% RH), select a Y-shaped olfactometer with an included angle of 60°, an inner diameter of 25mm, a main arm length of 25cm, and a side arm length of 20cm, and connect activated carbon filtration and sterile water washing cylinders, and air flow meters. The bioassay was carried out in a dark room from 8:00 to 16:00, and the measurement results were observed with a red light source. Pipette gun to draw 20 μl of attractant and drop it on the filter paper strip (2×5cm), place it in the odor bottle connected to a side arm of the Y-shaped olfactometer, put the same amount of liquid paraffin dropwise on the filter paper strip of the same size, and then A scent bottle attached to the other side arm was placed as a control. Adjust the flow of both arms of the Y-shaped tube in the system and set it to 100ml / min; insert a coffee bean elephant that has been...

Embodiment 2

[0038] The trapping and killing effect of embodiment 2 attractant on coffee bean weevil

[0039] From July 15th to August 30th, 2015, an attractant experiment on coffee bean elephants was carried out in the warehouse of Gubeichun Brewery in Wucheng County, Dezhou City, Shandong Province, where the brewed Daqu was stored. The test was carried out in 50 coffee bean elephant occurrences in relatively consistent trouble warehouses, and each warehouse was equipped with a formula of attractant and an equal amount of liquid paraffin as a control. The coffee bean weevil adults in the traps were investigated every other day, and the traps were recorded and replaced according to male and female. After 45 days of continuous investigation, the total cumulative trapping amount of each formula was counted, and each formula was repeated three times. Benzyl alcohol, 2-phenylethanol, benzyl acetate, and phenylethyl acetate were formulated with liquid paraffin to prepare 100 mg of attractant re...

Abstract

The invention provides an araecerus fasciculatus attractant and application thereof. The araecerus fasciculatus attractant comprises the following components in percentage by weight: 3 to 15 percent of benzyl alcohol, 30 to 42 percent of 2-phenethyl alcohol, 15 to 20 percent of benzyl acetate and 32 to 43 percent of phenethyl acetate. The attractant is prepared from secondary metabolic products of microorganisms, is simple in structure, is wide in sources, and is low in price; an induced cell manufacturing method is simple and convenient; an application method is simple, and labor strength is low; a trap device containing the induced cell can be suspended above a stored good, and is extremely suitable for controlling the pests in storing environment.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to a coffee bean weed attractant and its application. Background technique [0002] Coffee bean weevil (Araecerus fasciculatus De Geer), also known as Araecerus coffeeae, belongs to Coleoptera (Coleop-tera), Longhorn Weevil (Anthribidae), is a kind of worldwide storage pest with wide distribution and damage. It is one of five potentially dangerous stored grain pests. Storage hosts seriously damaged by coffee bean elephants include cereals, Chinese herbal medicines, and brewing Daqu. The coffee bean weevil, a chewing pest, explodes under conditions of suitable temperature and humidity. It lays eggs and feeds in the host, causing the storage to be emptied, causing serious losses and affecting the quality of reprocessing agricultural products. [0003] Coffee beans seem to be the main pests of Daqu, an important raw material for liquor brewing. After overwinteri...
