Problems solved by technology

[0004] Although the activity of sex pheromone lures is closely related to the effect of controlling pear borer, the lure activity in the field is not very ideal and cannot meet the needs of practical applications; in addition, the composition of sex hormones is complex and diverse, and various components control The effects are different, and there is no sex hormone preparation that can be stably used in the control of pear borer.

Embodiment 1

[0027] Refer to Table 1 to prepare the attractant for the small pear borer to study the attractant effect of different dosage compositions on the small pear borer.

[0028] Table 1 Preparation of attractant for pear borer worm (dosage: μg)

[0029]

[0030] The above-mentioned pear borer worm attractant is added to the solvent methylene chloride organic solvent, 5% BHT is added to the solvent, and then dropped into the carrier rubber stopper. The lure is made after the solvent evaporates.

[0031] On August 3-7, 2013, the lure effect experiment was carried out in Taoyuan, the comprehensive test field of Urumqi Academy of Agricultural Sciences, Xinjiang. The trap used is a water basin trap with a diameter of 20 cm. Add 0.5% washing powder to the water of the basin lure. The trap is hung on the branch of the peach tree, about 1.5m above the ground. Keep the water surface of the lure core and the water basin trap at 1-2cm. Each trap is about 20m apart. 4 repetitions were...

Embodiment 2

[0038] The attractant of each combination of the above-mentioned Example 1 was carried out in Taoyuan, a comprehensive test field of Urumqi Academy of Agricultural Sciences, Xinjiang, and the test time was August 10-17, 2013. Test method is with embodiment 1, and experimental effect is as shown in table 3 below:

[0039] Table 3. Attractive effects of different attractants on pear borer in Taoyuan

[0040]

[0041] Different same letters in the same column mean that the difference is not significant p<0.05, Duncan method test

[0042] The test results in Table 3 show that the number of pear borers attracted by treatments E and F is the largest, followed by treatments C and D.

Embodiment 3

[0044] Test method is the same as embodiment 1. The test time is August 15-22, 2013. The test results are shown in Table 4

[0045] Table 4. Attractive effect of different attractants on pear borer in Taoyuan (dose: μg)

[0046]

[0047] Different same letters in the same column mean no significant difference p<0.05, tested by Duncan method.

[0048] The test results in Table 4 show that 4 different treatments can attract a large number of pear borer. However, the blank lures did not attract the target pests.

Abstract

The invention discloses an oriental fruit moth imago attractant. The oriental fruit moth imago attractant consists of cis-8-dodecylene acetate, trans-8-dodecylene acetate, cis-8-dodecylene-1-alcohol and trans, trans-8,10-dodecadienoic-1-alcohol. On the basis of the oriental fruit moth imago attractant, the invention further discloses a lure based on the attractant and a preparation method of the lure. The attractant disclosed by the invention has a good attraction effect on oriental fruit moth imagoes, can be used for monitoring the occurrence dynamics of the field oriental fruit moths, and can be used for directing chemical prevention or directly preventing the oriental fruit moths through large-amount trapping and killing.

Description

technical field [0001] The invention relates to an attractant for adult pear borer moths, which belongs to the field of pest control. Background technique [0002] Grapholitha molesta Busck is a worldwide fruit tree pest, also known as pear moth, oriental fruit moth, referred to as pear moth, which belongs to Lepidoptera Lepidopteridae. It mainly damages pears, apples, peaches, hawthorns, apricots, etc. fruit trees. In China, except for Tibet, it is widely distributed in all parts of the country, especially in the peach and pear producing areas of Northeast, North China, Northwest, and East China; abroad, it is distributed in other countries in Asia, Europe, South America, North America, North Africa, Middle East, New Zealand, Australia. [0003] For many years, chemical pesticides have been the main method of controlling pear borer-eating insects. Due to the frequent use of chemical pesticides, the resistance of pests has developed rapidly, and the killing effect on pests...
