Description

Red Palm Weevil Traps

technical field

The utility model relates to a trap for palm plant pests, in particular to a trap for red palm weevils for trapping adults of red palm weevils.

Background technique

The red palm weevil Rhynchophorus ferrugineus (Oliver), also known as the rusty palm elephant, belongs to the family Curculionidae of Coleoptera Coleoptera. It is a serious and destructive pest of palm plants. Its hosts include coconut, betel nut, oil Palm palm, king palm, date palm, canary date palm, silver date palm and other palm plants. The red palm weevil lays eggs as adults in the leaf axils of plants or in wounds and cracks. After the eggs hatch into larvae, they start to feed on the surrounding soft tissue, and gradually feed on the deep part of the plant. The larvae drill into the inside of the trunk, bite off the fiber tissue of the trunk, and form criss-cross tunnels in the tree, causing the phloem and xylem of the plant to be damaged. to serious damage. The insect lives in seclusion, and it is difficult to find the damage in the early stage. In the later stage, it is found that most of the plants are damaged or dead. The red palm weevil is mainly distributed in parts of my country's Hainan, Guangdong, Yunnan, Zhejiang, Fujian, and Shanghai. The insect is very destructive to coconut trees and has seriously threatened the coconut plantation industry in Hainan. At the same time, the insect spreads through the transportation of palm plant seedlings, which has brought great trouble to the landscaping in many cities in southern my country. In 2005, Shanghai destroyed thousands of jujube trees due to the damage of the red palm weevil.

Field trapping of red palm weevil adults with aggregation pheromone and host fermentation products is a relatively effective control method. This method is not only safe for the surrounding environment, but also can monitor the activity of red palm weevil adults in real time and accurately.

At present, there are many reports at home and abroad on the trapping research of red palm weevil adults, but less research on its trapping equipment. The production and application of pheromone lure barrel" discloses a trap, which is a hanging trap, which has a large volume and a heavy load, and requires a solid fulcrum when hanging, so this trap is not suitable for young children. For use in coconut gardens, if you want to use it, you need to add a bracket as a fulcrum, which brings inconvenience to the trapping operation. In addition, the trap is mainly used to gather pheromones as bait for trapping, and it is not suitable for host fermented products as bait for trapping. Nor can it be used to gather pheromones and host fermented products as bait for trapping at the same time. The red palm weevil trap commonly used abroad is a barrel trap. The trap has a simple structure and is made of a plastic barrel with a cover. There are 3 to 4 insect entry holes on the cover, and the side of the barrel is also opened. There are 3 to 4 worm entry holes, and the aggregation pheromone is hung on the bottom of the cover, and the host fermentation product is placed at the bottom of the barrel. Although the trap has a certain trapping effect, it also has certain limitations. On rainy days, water tends to accumulate in the barrel, which makes the smell of the host fermented product disappear and affects the trapping effect. flee. Therefore, according to the living habits and activity characteristics of the red palm weevil, it has become an urgent task to develop a kind of trap suitable for trapping adults to control the harm and spread of this pest.

Utility model content

The purpose of the utility model is to provide a trap that can effectively trap adults of the red palm weevil. It is easy to make, easy to use, has good trapping effect on adults, and can be widely used in coconut planting areas and palm plant gardens.

The technical scheme adopted in the utility model:

A red palm weevil trap comprises a trapping tube, an insect retaining board, and an insect collecting basin, wherein the trapping tube is composed of a bracket tube, a plug cover, and a pheromone suspension frame, and the bracket tube is a smooth tube with a smooth inner wall, so that The introduced adults are not easy to escape. The pheromone suspension rack is set in the support tube to hang the pheromone or host fermentation product. The support tube is provided with a crawling coarse mesh surface and insect entry holes, which can effectively attract red palm weevil adults. (especially smaller adults) and smoothly introduce it into the lower part of the support tube through the worm hole; the plug cover can be opened and closed on the top of the support tube to block the support tube; the insect retaining plate is evenly arranged on the On the circumferential surface of the support tube, use the tropism of the adult red palm weevil to its attractant (aggregation pheromone, host fermentation product), lure it to hit the insect barrier, make it fall naturally, and slide into the insect collection basin; Insect traps are used to place trap tubes to collect captured adults.

When using, place the insect collecting basin first, set the insect baffle plate on the trapping tube and put it into the insect collecting basin, pour a certain amount of clear water into the insect collecting basin, open the plug cover, and put the pheromone or The host fermented product is hung on the suspension rack, and then the plug cap is tightly closed. The adults of the red palm weevil fly to the trap under the attraction of the lure, climb into the trap tube from the insect entrance hole, or fall down after hitting the insect baffle. Sliding into the insect trap, so as to achieve the purpose of trapping the red palm weevil.

In order to prevent that the clear water level in the insect-collecting basin is too high, so that the trapped red palm weevil escapes, an overflow hole is offered in the side of the insect-collecting basin.

The utility model has the advantages of simple structure, simple manufacture, convenient installation and use, not only can move freely, but also can be joined and disassembled freely, is very convenient for long-distance transportation, has good effect of trapping adults, and can be widely used in coconut planting areas and palm plant gardens .

Description of drawings

Fig. 1 is a structural representation of the utility model.

In the figure: 1. Plug cover; 2. Insect entry hole; 3. Crawling coarse mesh surface; 4. Insect barrier; 5. Support pipe; 6. Insect collection basin; 7. Overflow hole.

Detailed ways

In the structure shown in the figure, the utility model includes trapping pipe, insect retaining plate 4, insect collecting basin 6, wherein trapping pipe is made up of support pipe 5, plug cover 1, pheromone suspension frame, support pipe 5 It is a tubular object with a smooth inner wall, and the pheromone suspension frame is arranged in the support tube 5 for hanging pheromone or host fermented products. The crawling coarse mesh surface 3 and the insect entry hole 2 are arranged on the support tube, which can effectively attract insects. The palm weevil becomes an adult and successfully introduces it into the lower part of the support tube through the insect-entry hole. The plug cover 1 can be opened and closed on the top of the support tube 5 to block the support tube; the insect baffle plate 4 is evenly arranged on the support tube on the circumference of the surface, use the tendency of red palm weevil adults to its attractants to lure it to hit the insect baffle and then fall and slide into the insect collection basin; the insect collection basin 6 is used to place the trap tube, which can collect the caught adults.

In order to prevent the clear water level in the insect collecting basin from being too high, the red palm weevil trapped escapes, and the side of the insect collecting basin offers overflow hole 7.
