Description

A kind of long-legged bamboo elephant attractant

Technical field:

The invention relates to an attractant for trapping pests used in the fields of plant protection and environmental ecology, and mainly relates to an attractant for long-legged bamboo elephants.

Background technique

After the flood disaster in 1998, in view of the fact that the ecological environment has deteriorated due to the excessive consumption of natural forest resources in my country for a long time, my country began to implement the natural forest resource protection project. Returning farmland to plant bamboo is one of the main contents of returning farmland to forest in the natural protection project. After 2000, the bamboo forest area has been increasing at an annual rate of more than 90,000 hm ² , with an average annual net increase rate of 2.25%. The area of pure bamboo forest has increased significantly, large and small bamboo seas have emerged in various places, and the single variety and rich food source have created conditions for the large-scale occurrence of bamboo forest pests. According to incomplete statistics, the loss of bamboo forests due to insect pests reaches 21%, which is equivalent to reducing bamboo production by 10 billion kg of bamboo timber, more than 330 million kg of bamboo shoots, and a total output value of 4.2 billion yuan. Pests not only cause serious losses to the output and value of bamboo forests, but also aggravate the contradiction between supply and demand of bamboo. On the other hand, the aggravation of the contradiction between the supply and demand of bamboo has increased the pressure of timber ban and natural protection projects.

The giant bamboo elephant (Cyrtotrachelus buqueti Guer) belongs to the Weevil family of Coleoptera and is currently the main pest of bamboo forests. It is distributed in India, Cambodia, Vietnam, Indonesia, Japan, the Philippines, and China's Fujian, Taiwan, Jiangxi, Hunan, Sichuan, Guangdong, Guangxi, Guizhou, Yunnan and other places. The insect mainly harms Chinese bamboo (Sinocalamus afnis McClure), green bamboo (Bambuusa textiles MrClu), green bamboo (Bambusa oldhamii Munro), cotton bamboo (Dendrocalamus farinosus), pole bamboo (Bambusa pervariabilis McClure), pink bamboo (Lingnania chungii McClure) Bamboo shoots such as clumps of bamboo, larvae feed on the tip of bamboo shoots, the damage rate is 50%-80%, and the serious one is 100%. .

The serious harm of the long-legged bamboo elephant to bamboo shoots has long attracted the attention of scholars at home and abroad, but the insect not only spends a short time on the ground, but also develops underground for a long time, with a depth of more than 30cm, and is scattered throughout the bamboo forest area. The effective prevention and control of long-legged bamboo elephants is limited by many factors. In the prior art, the main method of preventing and controlling the long-legged bamboo elephant is to use chemical agents to kill it. Because the long-legged bamboo elephant is both a harmful insect and a resource insect, it causes serious harm to bamboo shoots on the one hand, and on the other hand it is a delicious delicacy that people like. The method of killing not only wastes natural resources, but also brings a vicious impact on the ecological environment. When people or other poultry or livestock eat the culled bamboo elephant by mistake, it is easy to be destroyed by the chemical residues in the long-legged bamboo elephant. Pesticides cause death, causing secondary pollution and destroying the ecological environment. At present, for the prevention and control of the long-legged bamboo elephant, it mainly focuses on the living habits of the long-legged bamboo elephant and the research on chemical, biological and artificial control measures, and there is no report on the in-depth analysis of the research on the long-legged bamboo elephant attractant.

Application research description: The effect research test is carried out in the observation room of adult behavior. A semi-cylindrical observation room with a wooden frame is designed and constructed, with a radius of 60 cm and a height of 90 cm, which is divided into 4 rooms. The adult release room is a semi-cylindrical body with the axis as the midpoint and a radius of 30 cm. The outside of the release room is divided into 3 parts to form 3 selection rooms. The rooms are separated by wooden boards. Purpose Nylon cloth is separated, and 2 circular holes of the same size and position with a diameter of 8 cm are reserved on each cloth for adults to enter and exit. A regression orthogonal design was adopted, repeated 3 times, and the design and implementation scheme are shown in Table 1. According to the experimental research plan, take benzaldehyde and other volatiles to make a compound solution, take 1g and absorb it on 0.5g absorbent cotton as a lure, put it in the adult selection room, and take 50 adults with strong vitality and put them in the middle adult release room , Turn off all the lights after releasing the worms, the time of picking up the worms is after 20:00 in the evening, and count the number of adults in each room under the red light before 7:00 the next day. Investigate the trapping number of adults in each release chamber, and calculate the average trapping rate. The results are shown in Table 1. The SSPS16.0 data analysis software was used to conduct statistical analysis and significance test on the test results.

According to Table 2, the attractants made of different weight ratios have different trapping rates, and the attractant mixed with 100 parts of benzaldehyde, 5 parts of indole and 90 parts of linalool has the highest trapping rate. According to Table 1, calculate the regression coefficient and establish the regression equation. Assuming that the average trapping rate of the adult bamboo weevil is y, and the factors affecting the trapping rate are x ₁ , x ₂ , and x ₃ respectively, then we have The regression equation y＝25.312+10.949x ₁ +2.511x ₂ +2.771x ₃ +2.999x ₁ x ₂ +1.674x ₁ x ₃ +1.241x ₂ x ₃ , according to the regression equation, each regression coefficient is positive, that is, benzene The effect of formaldehyde, indole, linalool and the interaction of the three factors on the average trapping rate y was positively correlated, and the average trapping rate y was the result of the combined action of the three factors and their interactions. Among them, benzaldehyde x ₁ contributed the most, followed by the interaction effect between x ₁ and x ₂ , linalool x ₃ , indole x ₂ , the interaction effect between x ₁ and x ₃ , and the interaction effect between x ₂ and x ₃ The interaction effect is relatively the lowest; the lack of fit test is carried out on the equation, F=1.937<F _0.05(2,3) ＝9.55, the difference is not significant, so it can be inferred that this experimental study is true and reliable; the regression equation is tested for significance, F =30.115>F _0.05(6,5) =4.95, the regression equation reached a significant level, the multivariate correlation coefficient between the trapping rate y and the influencing factors benzaldehyde x ₁ , indole x ₂ , and linalool x ₃ was 0.986, and the coefficient of determination was 0.973, it can be seen that benzaldehyde x ₁ , indole x ₂ and linalool x ₃ are the main influencing factors of the trapping rate y, and the regression equation is true and reasonable; the regression coefficient is tested by F, and the results are shown in Table 3. The regression coefficient b ₁ of x ₁ to y reaches a very significant level (P<0.01), that is, the impact of benzaldehyde on the trapping rate is extremely significant, and the regression coefficients of variables x ₂ , x ₃ , x ₁ x ₂ to y b ₂ , b ₃ and b ₄ both reached significant levels (P<0.05), that is, the interaction between indole, linalool and benzaldehyde and indole had a significant effect on the trapping rate, x ₁ x ₃ , x ₂ x ₃ had a significant effect on y The regression coefficients b ₅ and b ₆ reached a difference level of 25% (P<0.25), and the difference was not significant. Therefore, the trapping rate y was mainly composed of four treatment effects including benzaldehyde, indole, linalool and the interaction between benzaldehyde and indole.
