Description

Technical Field

[0001] The invention relates to the technical field of coffee pest control, and in particular to a method for killing Xylochaetes longipes in a small-grain coffee tree trunk by utilizing an infuser. Background Art

[0002] The tropical areas of Yunnan have a variety of ecological and climatic conditions. The climatic conditions and soil conditions in many tropical areas are very conducive to the growth of small-grain coffee. After years of development, Yunnan small-grain coffee has become the most important planting area in the country. In recent years, Yunnan Province has successively issued methods and measures to promote the development of Yunnan's coffee industry, which not only put forward valuable suggestions for the sustainable development of Yunnan's coffee industry, but also pointed out the direction for the development of Yunnan's coffee industry. The implementation of these methods and measures has greatly promoted the development of Yunnan's coffee industry and improved the quality of Yunnan coffee. The brand awareness of "Yunnan Coffee" has been continuously improved in domestic and foreign markets, and the Yunnan coffee industry has entered a new stage of development. With the rapid development of Yunnan's coffee industry, coffee garden pest management has become a prominent issue. Coffee extermination of Xylotreya longicornis ( Xylotrechus quadripes ) has always been an important insect pest in Yunnan's low-altitude coffee plantations. Severely damaged coffee plantations will cause coffee production to reduce by more than 80%, seriously restricting the development of small-grain coffee cultivation in Yunnan's low-altitude areas.

[0003] The coffee beetle is the main stem borer of small-grain coffee. The larvae live in the wood of the coffee tree branches and use their own excrement to seal the boreholes. Insecticides are difficult to prevent and control them. The time of adult emergence is scattered and the duration is long. The egg-laying period of adult individuals is short. The cost of drug control is high and the harm to the environment is great, which is inconsistent with the concept of sustainable development. Although the composite cultivation method of planting shade trees has a certain effect on the prevention and control of coffee beetles, excessive shading will seriously affect the yield of small-grain coffee. At present, the use of integrated control methods is a relatively effective method. Among the integrated control methods, timely burning of insect-infested branches is a traditional control method. Because the insect branches need to be handled in time, this method not only cannot use the insect branches as a kind of firewood, but also is affected by the high water content of the branches during burning, and additional fuel needs to be added to achieve the burning effect, thereby increasing the cost of control. In addition, burning branches is an unfriendly environmental behavior and will have a certain negative impact on the environment. In addition to burning the insect-infested branches, some people also use the method of soaking in a pool to kill the insects in the tree trunk. This method effectively solves the problem of high cost and environmental pollution of burning insect branches, but due to the lack of a reasonable soaking method, the soaking time is long and the efficiency is low. Experience shows that if the insect branches are soaked in flowing water, the larvae in the branches can survive for more than half a month. If the soaking pool is open, the emerging adults may still fly out of the soaking pool, thereby reducing the prevention and control effect. In order to improve the efficiency and prevention and control effect of the soaking method for preventing and controlling the coffee beetle, it is urgently necessary to invent a simple, practical, efficient and low-pollution coffee beetle soaking method for insect branches.

[0032] Example 1

[0033] Step 1. Collection of damaged branches: The branches and trunks damaged by the coffee beetle were collected in the coffee garden, and the pest-free side branches were removed. They were divided into three diameter classes according to the diameter class: less than 2 cm, 2-5 cm, and greater than 5 cm. They were also processed into a specific length of less than 3 cm of the box length, with 30 damaged branches in each diameter class.

[0034] Step 2. Soak the affected branches: Place the soaker for the damaged branches of the coffee beetle in direct sunlight, bundle the damaged branches of the same diameter into a unit, and place them in the soaker. After all the damaged branches are placed, press the soaked damaged branches with submerged heavy objects to prevent them from floating. Then close the water outlet valve, inject clean water and make it cover the soaked branches by about 3 cm, cover the lid and soak for 4 days, 7 days, and 10 days.

[0035] Step 3. Complete the soaking treatment of the affected branches and trunks: After the damaged branches are soaked in the soaker for a period of time, all the coffee-killing Xylodon longipes in the damaged branches are dead, the water outlet valve is opened, the water in the soaker is drained, the soaker cover is opened, and the damaged branches are taken out to complete the soaking; The soaker comprises a soaker cover, a soaking box, a water outlet valve and a movable wheel; The soaker cover is placed on the soaking box after the soaker is filled with water; The soaking box includes a handle, a box body, a movable wheel axle, a water outlet and a fixed foot. The handle is directly connected to the box body. The movable wheel axle is located at the lower left corner of the box body and is connected to the movable wheel through the movable wheel axle hole. The bottom right side of the box body has a water outlet for installing a water outlet gate valve. The fixed foot is located at the bottom of the box body and plays a fixing role when placed; The water outlet gate valve is connected to the water outlet of the box; The movable wheel is installed on the movable wheel shaft at the lower left corner of the box body.

[0036] In order to further illustrate the effect of the present invention, the present invention also sets the following comparative example

[0037] Comparative Example 1

[0038] Compared with Example 1, the difference is that step (2) uses a pool of water to soak the coffee beetle-killing branches and trunks affected by the beetle.

[0039] Effect column 1

[0040] The damaged branches and trunks that were soaked in the above-mentioned Example 1 and Comparative Example 1 were respectively dissected to check the survival status of the coffee-killing Xylodon longipes in the branches and trunks, and their mortality rate was calculated. The results are as follows:

[0041] It can be seen from the results in the above table that the soaking effect of Example 1 is significantly better than that of Comparative Example 1, indicating that the insect-infested branches and trunks treated with the soaker are more efficient. Therefore, the application of the soaker shows a more excellent effect in the control of coffee-killing tiger longhorn beetles in branches and trunks, further proving its advantages in practical applications.
