Embodiment 1

[0024] Example 1 Behavior selection test of Aphid chrysanthemum to 4 kinds of volatile compounds

[0025] 1. Material method

[0026] 1.1 Breeding and collection of Aphis chrysanthemum

[0027] Aphid chrysanthemum was collected from the experimental greenhouse of the National Flower Engineering Technology Research Center of Beijing Forestry University. Before the experiment, the 4th instar wingless nymphs of Aphis chrysanthemum were collected, inoculated on the aphid-susceptible chrysanthemum variety 'Jinglin Qiuge', and raised in gauze bags. During the Y-tube behavior selection test, wingless adult aphids were randomly collected from gauze bags for behavioral tests.

[0028] 1.2 Preparation of 4 kinds of volatile chemical standards

[0029] Among the 4 volatile matter standards, β-ocimene (CAS number: 13877-91-3; Sigma product number: W353901) and cis-4-thujyl alcohol (CAS number: 546-79-2; Sigma product number: 96573) was purchased from Sigma Reagent China Company; L-bor...

Embodiment 2

[0039] Example 2 Interference of cis-4-thujol and α-humulene on feeding behavior of Aphid chrysanthemum

[0040] According to the results of Example 1, both 0.1% cis-4-thujyl alcohol and 1% α-humulene can significantly repel adults of Aphis chrysanthemum. This example further verifies the interference effect of these two compounds on Aphis chrysanthemi in the actual feeding state.

[0041] 1. Material method

[0042] When the cutting seedlings of the chrysanthemum 'Jinglin Qiuge' grow to 8-10 leaves, inoculate 5 adult aphids of Chrysanthemum chrysanthemum, and bag them to reproduce freely. After 10 days, a certain number of aphids proliferated on the inoculated chrysanthemums, and they were all in a normal feeding state. At this time, using a 10 μl pipette gun, pipette 10 μl of solvent n-hexane (as a control), 0.1% cis-4-thujyl alcohol and 1% α-humulene solution respectively, and place them on the 2- Release around 3cm. A video camera was used to record the behavioral resp...

Abstract

The invention discloses a microsiphum chrysanthemi repellent and application thereof. The active ingredient of the repellent is cis-4-cacumen biotae alcohol, and the repellent is a non-toxic compound and can stop feeding of the macrosiphum avenae, pull out a piercing-sucking mouthpart and escape from a feeding object. The repellent provided by the invention has an obvious repelling effect on the macrosiphum avenae, can realize a good prevention and treatment effect, and promotes sustainable development of the chrysanthemum industry.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to a repellent for Aphis chrysanthemum and its application. Background technique [0002] Macrosiphoniella sanborni (Macrosiphoniella sanborni) is an oligophagous insect that mainly damages plants of the genus Chrysanthemum in the family Asteraceae. Chrysanthemum chrysanthemum sucks plant juice, causing leaves to chlorotic, yellow, wilt, and even dry, resulting in abnormal growth and development of chrysanthemums, and even more damage during flowering, seriously affecting the quality of ornamental chrysanthemums and medicinal chrysanthemums. The honeydew secreted by Aphid chrysanthemum can cause sooty rot and seriously affect the ornamental value. In addition, as the carrier of pathogens such as chrysanthemum stem necrosis virus, chrysanthemum chlorosis virus, and chrysanthemum dwarfing virus, Aphid chrysanthemum poses an extremely serious threat to the production ...
