Description

A device for trapping fruit flies in the field

technical field

The utility model relates to a device for trapping fruit flies in the field.

Background technique

At present, field control of fruit flies is mainly carried out by spraying plant-derived pesticides matrine, rotenone, veratrine and pyrethrins. Or by using the phototaxis of Drosophila to trap and kill Drosophila males with sex lures. However, the traps of traditional traps have trapping holes concentrated in the upper and middle parts of the bottle in rows, with complex structures, low trapping effect, and easy escape. Although the spraying method has a good effect on the chemical control of fruit flies, it is easy to cause excessive pesticide residues in the fruit, and then cause pesticide pollution to the environment.

Utility model content

The purpose of the utility model is to provide a device for trapping fruit flies in the field, which can greatly reduce the control cost while being efficient, simple, free of pesticide pollution and improving the control effect.

A device for trapping fruit flies in the field, which is special in that it includes a bottle body, a bottle mouth is opened on the top of the bottle body, a bottle cap is detachably installed on the bottle mouth, and a hook is installed on the bottle cap A mesh tray is installed in the middle of the inner wall of the bottle body, a trapping plate is installed in the middle of the tray, the bottom of the bottle body is sunken into the bottle and a trap hole is arranged in the middle of the bottom of the bottle body.

Wherein the edge of the tray is inlaid on the slot on the inner wall of the bottle body.

Wherein the body of the bottle is conical, and the bottom of the body of the bottle is sunken into the bottle to be conical.

The trapping hole is circular with a diameter of 4-8mm.

In order to solve the harm of fruit flies to grape fruits during picking and avoid the influence of chemical pesticides on fruit quality, the device of the utility model replaces the chemical control of fruit flies with a simple and efficient trapping method to ensure the quality of grape fruits. Specifically, the trap is made into a conical shape, and the trap hole is opened at the upper end of the chasing bottom to increase the diffusion area of the trapping odor on the outer surface of the container, improve the trapping effect in the field, and effectively prevent the trap from entering the trap. Fruit flies flee. When in use, the lures with pesticides are put into the container, and the volatilization of the lures attracts fruit flies into the device to kill or be trapped therein to achieve a good control effect.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model.

Detailed ways

As shown in Figure 1, the utility model provides a kind of device of trapping fruit fly in the field, comprises bottle body 5, has bottle mouth at the top of this bottle body 5, is detachably installed with bottle cap 2 at this bottle mouth place, A hook 1 is installed on the bottle cap 2, and a mesh tray 3 is installed in the middle of the bottle body 5 inner walls, thereby facilitating the volatilization of the trapping liquid. It is sunken in the bottle and has a trapping hole 4 trapping hole diameter 4-8mm in the middle of the bottom of the bottle body 5 .

Wherein the edge of the tray 3 is inlaid on the draw-in groove on the inner wall of the bottle body 5, and the bottle body 5 is conical in addition, and the bottom of the bottle body 5 is conical in the concave shape in the bottle.

Using method and working principle of the present utility model are:

When in use, the bottle body 5 is suspended on the surface of the grape shelf through the bottle mouth hook 1, the bottle cap 2 is opened by the bottle mouth, and the existing conventional trapping liquid is placed on the trapping plate, and the trap can pass through the trap. The volatilization of the fruit flies into the device to kill or become trapped in it.
