[0026] In the present invention, the preparation method of the lure core preferably includes the following steps:
[0027] a. Mix trans-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 and 100 μL of the attractant, and then place it under natural conditions until the organic solvent evaporates to dryness to obtain the attractant.
[0029] The present invention provides a method for trapping peach borer adults based on the lure core combined with LED lights, which includes the following steps:
[0030] 1) Fix the wick on the upper part of the basin-type trap with trapping liquid, and the vertical height of the wick from the center of the water surface of the basin-type trap is 0.8-1.2cm;
[0031] 2) Fix the LED lamp on the upper part of the basin trap with trapping liquid, and the vertical height of the LED lamp from the center of the water surface of the basin trap is 2.5-3.5...
Embodiment 1
[0045] The mass ratio of the sex pheromone components of peach borer, trans 10-hexadecenal (E10-16: Ald) and 10-hexadecenal (Z10-16: Ald) was selected to be 80:20, and the mass ratio was changed to 80:20. The color of the core is used to calculate the amount of moth traps to obtain the best color of the sex pheromone core of peach borer.
[0046] Preparation of lure core: use the prepared 1mg / 100μL attractant and add it to the lure cores of different colors. The total volume of the attractant added to each lure core is 100μL. After the solvent hexane evaporates and dry, the lure core is made.
[0047] Setting of traps: Fix the made traps to the triangular traps. The traps are fixed to the middle branches of the chestnut tree with iron wires, about 1.5-2m from the ground, neatly arranged on the chestnut field. A single row contains all the traps for processing. The traps for each treatment are separated by 10-12 meters, each treatment is repeated 4 times, and the trap position is ch...
Embodiment 2
[0053] The experiment of different proportions of sex core attracting moths by peach borer started from August 31 to September 28, 2015. The test site was located in the chestnut mountain (29°19′N, 119) of Nanpu Village, Shouchang Town, Jiande City, Zhejiang Province. °14′E).
[0054] Select and fix the main components of sex pheromone of peach borer, cis 10-hexadecenal (Z10-16: Ald), trans 10-hexadecenal (E10-16: Ald), hexadecenal (16 :Ald) Mix in a certain proportion (see Table 2 for specific proportions) to make lures for field trials. The total dose of each lure is 100μL.
[0055] Induction core production: cis 10-hexadecenal (Z10-16: Ald), trans 10-hexadecenal (E10-16: Ald), octadecenal (16: Ald), using n-hexyl The alkane is dissolved and prepared as a 1mg / 100μL solution. Add quantitatively each sex pheromone component solution, wait until the solvent n-hexane evaporates and dry to make a lure core.
[0056] Setting of traps: Fix the made traps to the triangular traps. The tr...
