[0002] Lycium barbarum red gall midge is a typical gall-causing insect that specializes in feeding. It mainly lays eggs on the top of the young flower buds of wolfberry as adults. After hatching, the larvae feed on the ovary of the flower buds, causing the flower buds to deform and swell to form lantern-shaped galls, resulting in the flower buds not blooming normally. result

Embodiment 1

[0028] This embodiment provides a method for preparing a plant-derived attractant for Lycium chinensis, and the preparation system for realizing the preparation method is as follows: figure 1 As shown, the method includes the following steps:

[0029] Select fresh flower buds 1 collected from healthy wolfberry plants, and put them into the gas washing bottle 2. The capacity of the gas washing bottle 2 is 100mL. The material of the gas washing bottle 2 should not be adsorbed, chemically changed, or interfered with terpenes. material, and the material is stable and high temperature resistant, which can ensure that no volatile gas is released, such as glass, which is sealed with a cork;

[0030] The bottle stopper of the gas washing bottle 2 is provided with an air inlet 21, and the air tank 4 is connected to the air inlet 21 of the gas washing bottle 2 through a flow meter 5, an activated carbon filter bottle 6, and a distilled water humidifying bottle 7 in sequence through a Te...

Embodiment 2

[0036] This embodiment is an application method of the attractant of Lycium barbarum red gall midge described in Example 1. Specifically, the attractant of Lycium barbarum red gall midge is dripped on a filter paper sheet to make an attractant filter paper sheet, and a Y-type olfactometer is used to measure the attractant. Attraction and trapping of adults of Lycium barbarum red gall midge by agent filter paper sheets.

[0037] Such as figure 2 As shown, the Y-shaped olfactometer consists of a Y-shaped glass tube 10, two taste source bottles 20, two distilled water humidification bottles 30, two activated carbon filter bottles 40, two air flow meters 50, an atmospheric sampler 60 and two A Teflon connecting pipe 70 is composed. The air inlets on both sides of the Y-shaped glass tube 10 are respectively connected to a flavor source bottle 20, a distilled water humidification bottle 30, an activated carbon filter bottle 40, and an air flow meter 50 through a Teflon connecting ...

Embodiment 3

[0046] This example is another application method of the wolfberry red gall mosquito attractant described in Example 1, specifically: the wolfberry red gall mosquito attractant is made into a lure core and the viscose-type trap is used to trap wolfberry in the field Adult red gall midge.

[0047] The lure core of the wolfberry red gall midge attractant is composed of the following components according to the total mass percentage: 94%-98% of the wolfberry red gall midge attractant, 1%-3% of the UV328 agent, BHT (2,6-di tert-butyl p-cresol) 1%-3%. Among them, the UV328 agent acts as an anti-ultraviolet stabilizer, and BHT has an anti-oxidation effect and acts as a stabilizer for lures.

[0048] The preparation method of the lure core of the wolfberry red gall midge attractant comprises the following steps: uniformly mixing 94%-98% of the wolfberry red gall midge attractant, 1%-3% of UV328 agent and 1%-3% of BHT according to the formula ratio Quantitatively added to the slow-r...

Abstract

The invention relates to a preparation method and application of a botanical attractant for a Chinese wolfberry gall midge. The method comprises the following steps that: 3-5g of fresh flower buds areselected collected from healthy Chinese wolfberry plants, the selected flower buds are put into a gas washing bottle, and the gas washing bottle is plugged and sealed with a bottle plug; an air inletand an air outlet are formed in the gas washing bottle, the air inlet is communicated with a clean air source, and the air outlet is communicated with an air collecting device, so that air in the gaswashing bottle can be replaced with clean air without impurities; the gas outlet is communicated with an adsorption pipe filled with an adsorbent; and the clean air is continuously injected into thegas washing bottle through the gas inlet and then exhausted to the adsorption pipe through the gas outlet, and the gas is collected circularly in this way, and the gas is continuously collected for several hours; and after the collection is finished, the collected gas is leached and eluted by adopting a polar organic solvent, so that the botanical attractant for Chinese wolfberry gall midge can beobtained.

Description

technical field [0001] The invention relates to the technical field of agricultural pest control, in particular to a preparation method and an application method of an environment-friendly wolfberry red gall midge plant source attractant. Background technique [0002] Lycium barbarum red gall midge is a typical gall-causing insect that specializes in feeding. It mainly lays eggs on the top of the young flower buds of wolfberry as adults. After hatching, the larvae feed on the ovary of flower buds, causing deformed and enlarged flower buds to form lantern-shaped galls, resulting in flower buds not blooming normally. result. The life history of Lycium barbarum gall midge goes through four developmental stages: eggs, larvae, pupae, and adults. The first three stages live in galls and soil, which are highly concealed and extremely difficult to control. The rate of flower bud damage is the rate of yield loss. It is known as "goji berry cancer". In recent years, wolfberry red ga...
