[0026] In the present invention, the preparation method of the lure preferably includes the following steps:
[0027] a. Mix trans-10-hexadecenal and cis-10-hexadecenal in a ratio of 900:100, and dilute with an organic solvent to obtain an attractant;
[0028] b. Mix the ethanol-treated carrier with 100 μL of attractant, and then place it under natural conditions until the organic solvent evaporates to dryness to obtain lure cores.
[0029] The present invention provides a method for trapping peach borer adults based on the lure core combined with LED lamps, comprising the following steps:
[0030] 1) The lure core is fixed on the upper part of the water basin trap equipped with trapping liquid, and the vertical height of the lure core from the center of the water surface of the water basin trap is 0.8~1.2cm;
[0031] 2) LED lights are fixed on the top of the water basin trap equipped with trapping liquid, and the vertical height of the LED light from the center of the water ...
Embodiment 1
[0045] The mass ratio of trans-10-hexadecenal (E10-16:Ald) and 10-hexadecenal (Z10-16:Ald) was selected as the sex pheromone component of peach moth moth to be 80:20. The color of the core is used to count the amount of moth lures, and the best color of the cores for sex pheromone lures of the peach moth moth is obtained.
[0046] Lure production: use the prepared 1mg / 100μL attractant, add it to different color lures, the total volume of each lure added with attractant is 100μL, and wait for the solvent n-hexane to evaporate to dryness to make lures.
[0047] Trap setting: fix the prepared lure core on the triangular trap, and fix the trap on the middle branch of the chestnut tree with iron wire, about 1.5-2m from the ground, and arrange it neatly on the chestnut field. A single row contains all the processing traps, The traps for each treatment were separated by 10-12 meters, and each treatment was repeated 4 times, and the positions of the traps were changed after 1-2 days o...

[0053] The test of attracting moths with different proportions of peach moth moths started from August 31 to September 28, 2015. The test site is located in Chestnut Hill, Nanpu Village, Shouchang Town, Jiande City, Zhejiang Province (29°19′N, 119 °14′E).
[0054] Selecting and fixing the main components of sex pheromone of peach moth moth, cis-10-hexadecenal (Z10-16:Ald), trans-10-hexadecenal (E10-16:Ald), hexadecenal (16 :Ald) were mixed in a certain proportion (see Table 2 for specific proportions) to make lures for field trials, and the total dose of each lure was 100 μL.
[0055] Manufacture of lures: cis-10-hexadecenal (Z10-16: Ald), trans-10-hexadecenal (E10-16: Ald), octadecenal (16: Ald), and n-hexadecenal Dissolved in alkane and prepared as a 1mg / 100μL solution. Quantitatively add the various pheromone component solutions, and wait for the solvent n-hexane to evaporate and dry to make lures.
[0056] Trapper setting: fix the prepared lure core on the triangular tr...
