[0049] Example 2 The effect of the chrysanthemum chrysanthemum repellent is significantly better than that of the single-component repellent

[0050] 1 Materials and methods

[0051] In October 2020, when the white chrysanthemums are in full bloom in Tongxiang City, Zhejiang Province, from 10:00 to 12:00 on October 24, select a chrysanthemum garden where chrysanthemum chrysanthemum aphids have seriously occurred over the years. It is divided into 6 areas, and each area has 1 One kind of repellent is placed in the treatment, each treatment is 2 mu of chrysanthemum garden, 6 treatments are set randomly, and the distance between treatments is 20m.

[0052] Control (CK) test area: with an area of ​​2 mu, 30 yellow insect-attracting boards are placed, and the distance between the boards is 7m×8m. The bottom edge of each insect trap is slightly higher than the chrysanthemum branches and leaves, and a rubber head containing 200 μL of n-hexane, that is, a n-hexane core, is tied on th...

[0065] Example 3 The field control effect of repellent-traps composed of chrysanthemum chrysanthemum repellent and yellow trap board

[0066] 1 Materials and methods

[0067] 1.1 Experimental design

[0068] On October 27, 2020, when the chrysanthemums were in full bloom in Tongxiang City, Zhejiang Province, a chrysanthemum orchard with a serious damage from the chrysanthemum chrysanthemum was selected and divided into 3 areas, each area was 2 mu, with a distance of 20m between each other: one was used as a chrysanthemum chrysanthemum The test area for the repellent of Aphis chrysanthemum, one is the test area for the slow-release agent of Aphis chrysanthemum repellent, and the other is the CK area. From 10:00 to 12:00 on October 27, the investigation of the base number of aphids before trapping and killing was completed, that is, sampling was taken at five points in each test area, and each sample point was 2m 2 , randomly select 20 chrysanthemums in each sample point, and ...

Abstract

The invention provides a macrosiphum avenae repellent and a use method thereof. Naphthalene, camphene, limonene and E-beta-farnesene are combined in proportion to prepare the macrosiphum avenae repellent with the total dosage of 80 mg/mL to 110 mg/mL. The macrosiphum avenae is an important pest of chrysanthemum, chrysanthemum plants are always damaged by the macrosiphum avenae from the seedling stage of April to the end of the flowering stage of December, and particularly in the flowering stage of October to December, the macrosiphum avenae enters flower hearts and emerges in chrysanthemum soup along with processing, storage, transportation and brewing of the chrysanthemum, so a drinker burns out of appetite. In the florescence of chrysanthemum, the repellent is loaded on a rubber head to prepare a repellent core, the repellent core is attached to a chrysanthemum branch, and the repellent is slowly released to repel aphids; meanwhile, a yellow insect trapping plate is placed above a chrysanthemum cluster near the repellent core to trap and kill the aphids, and the damage of the aphids to the chrysanthemums is reduced and avoided. 13-17 sets of repellent cores and insect trapping plates are placed in each mu of the chrysanthemum garden. After the repellent is loaded into each lure, the stabilizer and the slow-release agent are loaded, so the repellent effect can be prolonged for a longer time.

Description

technical field [0001] The invention belongs to the field of plant protection, and relates to the use of insect pheromones to repel and trap the important pest chrysanthemum chrysanthemum aphid. From October to December when the chrysanthemums are in full bloom, fix the repellent core on the chrysanthemum branches in the chrysanthemum bushes, and place a yellow insect-attracting sticky board on the top of the chrysanthemum bushes near the repellent core, and the bottom edge of the board is slightly higher than the chrysanthemum bushes. The repellent distributed by the repellent core will drive away the chrysanthemum chrysanthemum on the chrysanthemum, and the chrysanthemum will fly to the yellow insect trap and be trapped, thereby greatly reducing the chrysanthemum population in the chrysanthemum garden and avoiding the chrysanthemum chrysanthemum Damage chrysanthemum petals and young leaves of chrysanthemums, avoid chrysanthemum aphids from penetrating into chrysanthemums and...
