Description

Technical Field

[0001] The utility model relates to a trapping device, in particular to a trapping device for trapping corn borer larvae in a field. Background Art

[0002] When controlling corn borers in the field, pesticides are often applied into the trumpet of the corn heart leaf at the end of the season. This is still the best pesticide control method for controlling the first generation of spring corn and the second generation of summer corn borers in northern my country. This method can also be used to trap corn borer larvae in the field. By throwing traps into the trumpet of the corn heart leaf at the end of the season, the corn borer larvae are lured to drill in. This is not only convenient for collection, but also avoids the traditional capture method of peeling off the heart leaf of the corn seedling, thereby reducing damage to the corn seedlings and insects. However, the existing trapping devices have complex structures and are very inconvenient to use. For example, a Chinese patent with announcement number CN208047791U discloses a novel corn borer larvae diapause induction box device, including a main box, a sponge block and a heating lamp. The side end face of the main box is fixedly installed with a protective box through a fixed block, a light source is installed in the protective box, a glass tube is fixedly installed on the inner wall of the main box corresponding to the entry plate, a handle and a battery are installed on the upper end face of the main box, an air vent is provided on the upper inner wall of the main box, the heating lamp is fixedly installed on the upper inner wall of the main box, a water tank is fixedly installed on one side of the heating lamp, a micro water pump is fixedly installed on the inner wall of the bottom end of the water tank, a water outlet is provided at the lower end of the water pipe, a refinement nozzle is fixedly installed in the water outlet through a fixed pipe, the sponge block is fixedly placed below the refinement nozzle, and the upper end face of the sponge block is covered with fresh corn stalks. The device has the advantages of trapping corn borer adults to lay eggs on corn stalks and causing corn borer larvae to develop into a diapause state inside the stalks. However, it still has the disadvantages of being complex in structure and being very inconvenient to use. Utility Model Content

The trapping device can quickly trap and collect corn borer larvae in the field, while reducing damage to corn seedlings and reducing manual capture and damage to insect bodies. In actual work, during the trumpet mouth period of the corn heart leaf at the end, which is also the period when corn borer larvae are seriously harmful, the trapping column is taken out from the trapping column collection box. When in use, the bottom cover of the trapping column is opened and cotton that has absorbed the attractant is placed on it. After reinstalling, the trapping column is thrown vertically into the trumpet mouth of the corn seedling. At this time, the corn borer larvae are hatched and bore into the heart of the corn seedling. The corn borer is lured by the attractant, and after drilling into the column body from the circular attracting opening of the top cover of the trapping column, it is restricted by the size of the column body and the mesh gasket on the top cover, and cannot turn around and escape. After throwing the trapping column at the trumpet of the corn seedling for 24-48 hours, the trapping columns that have trapped corn borer larvae can be gradually collected and placed in the trapping column collection box. The trapping column contains attractants, which can maintain the activity of corn borer larvae for at least 2-3 days and will not cause the corn borer larvae to starve to death. The column, top cover and bottom cover are all provided with grid holes to maintain air circulation, avoid the insect body from being stuffy and dying of lack of oxygen, and can also better emit the smell of the attractant at the bottom of the column to attract corn borer larvae. After the field collection is completed and you return to the room, you can open the bottom of the trapping column and take out the corn borer larvae. Using the trapping device for trapping corn borer larvae in the field can reduce the damage to the corn seedlings and corn borer larvae caused by manually peeling the heart leaves of the corn seedlings to capture the corn borer larvae, and at the same time, it is convenient and quick to collect the corn borer larvae.
