Problems solved by technology

However, this type of medicament is highly toxic, has a short efficacy period, and seriously pollutes the environment. After spraying, the medicament mist floating in the air has caused potential threats to residents and pedestrians on both sides of the road; produce resistance to pesticides; in addition, the chrysalis borer has feigned death, and after spraying or disturbance, it will appear frightened and hang down, cleverly avoiding the contact effect of pesticides, and the falling larvae of the chrysalis will continue to grow after the spraying ends. Climb the tree to harm the parts that have not been sprayed with the agent
Therefore, it is urgent to develop and apply new efficient green control technology in view of the occurrence and damage characteristics of C. moth, and sex pheromone control technology has the advantages of high efficiency, non-toxicity, no residue, and is not easy to cause pest resistance, etc., and has been used in many It has been successfully applied in the prevention and control of agricultural and forestry pests, but the research on the identification of the sex pheromone of the camphor moth and its application in the control is blank at home and abroad, and needs to be strengthened urgently

Embodiment 1

[0031] Lure formula: including the following 6 treatments and 1 solvent control.

[0032] Formula 1: Take component I: trans-11-hexadecanol; component II: cis-11-hexadecene acetate, and prepare 1 μg / μl pheromone component solutions with organic solvent dichloromethane respectively, and then Then, the prepared above-mentioned components were formulated according to their mass ratio: component I: component II = 1:9 to prepare a sexual attractant for the camphor moth, with a concentration of 1 μg / μl.

[0033] Formula 2: Take component I: trans-11-hexadecanol; component II: cis-11-hexadecene acetate, and prepare a 1 μg / μl solution with the organic solvent dichloromethane respectively, and then prepare The above-mentioned components are prepared according to their mass ratio: component I: component II = 3:7 to prepare the sexual attractant of camphor moth, and the concentration is 1 μg / μl.

[0034] Formula 3: Take component II: cis-11-hexadecene acetate; component III: cis-11-hexa...

Embodiment 2

[0043] Experiments were carried out in Wujiang City, Jiangsu Province, during the occurrence of the second generation of the camphor borer. During the test, the basin-type traps were fixed with a triangular bracket, the traps were placed at a height of 1.5m, and the traps were separated by 20m. The lures of different treatments were randomly arranged, and each lure was repeated 3 to 5 times. Check the trapping results every morning, record the amount of moths in each trap, and replenish the water in the traps, and count the amount of moths after 30 days of continuous investigation. The results are shown in Table 1.

[0044]Table 1 The amount of field lures (heads) for different sex pheromone lures of C.

[0045]

[0046] Table 1 field experiment result shows: lure core formula 2 and 4~6 all have significant lure effect to camphor moth, and average lure moth amount is 6~22 times of contrast (formula 7); and formula 1 and 3 effect is poor , not significantly different from t...

Embodiment 3

[0048] A field experiment on the amount of moth trapping was carried out in Wujiang City, Jiangsu Province during the occurrence of the third generation of C. Lure formula, lure and trap type and field experiment method are all the same as example 1. The experimental results are shown in Table 2.

[0049] Table 2 The amount of moths lured by different sex pheromone lures in the field (head)

[0050]

[0051]

[0052] The results in Table 2 show that, compared with the control (formulation 7), lure core formulas 3 to 6 all have significant attracting effects on the camphor moth, and the average amount of moth lures is 6 to 16 times that of the control formula. The result is the same as that of Example 2, but the attracting effects of formulas 6-7 are still the best, and the difference between formula 6 and formula 7 is not obvious. The results of the two examples all show that formulas 6 to 7 are optimal formulas, which can be applied to the prevention and forecasting o...

Abstract

The invention discloses an othaga achatina butler sex attractant composition and its application. The othaga achatina butler sex attractant composition is composed of the following ingredients: cis11-hexadecenyl acetate, cis11-hexadecanol, cis9-trans12-tetradecene acetate, wherein the ratio of cis11-hexadecenyl acetate to cis11-hexadecanol to cis9-trans12-tetradecene acetate is (5-9): (0-3): (0-3), and cis11-hexadecenyl acetate and cis9-trans12- tetradecene acetate are not both zero at the same time. The othaga achatina butler sex attractant composition is applied in trap and insect forecasting of othaga achatina butler. No matter used for insect forecasting or used for trap and control of othaga achatina butler, the composition provided by the invention is beneficial to protecting natural enemies and enhancing control effect. In addition, application of chemical pesticides can be avoided or minimized so as to reduce pollution, protect the environment and remarkably raise economic, social and ecological comprehensive benefits.

Description

technical field [0001] The invention belongs to the field of plant protection, and in particular relates to a moth moth sex attractant composition and its application. Background technique [0002] Camphor tree (Cinnamomum camphora (L.) Presl), is an evergreen arbor of the family Lauraceae, native to southern China provinces, Vietnam, Japan and other places. Because of its full tree shape, tall tree vigor, fragrant branches and leaves, and evergreen seasons, it is currently widely planted in Jiangsu, Zhejiang, Shanghai, Hunan, Sichuan and other places, and has become an important garden and road greening tree species. However, in recent years, with the expansion of the planting range of camphor trees, the damage range of the camphor borer (Orthaga achatina Butler) has expanded and become more and more serious, and has become a major pest of camphor trees. [0003] The camphor moth, also known as the camphor moth or the camphor moth, belongs to the Lepidoptera moth family. I...
