The method for using the parasitic wasp suspension bottle for controlling fruit flies includes the following steps:

(1) the fruit fly pupa is loaded into the bottle body, and the bottle cap is screwed up and the baffle is closed;

(2) hanging the bottle body on the field crops;

(3) Open the flap, and unfold the climbing pole so that the climbing pole is in contact with the crop.

The beneficial effects of the present invention are as follows: the parasitic wasp suspension bottle for preventing and controlling fruit flies and the method of use provided by the present invention are easy to operate, and only need to put the parasitic wasp into the suspension bottle and hang the suspension bottle on the field crops; The bottle body can be recycled. After the fruit fly pupae are put in, the bottle body can be recycled and reused. The whole hanging bottle has simple structure, low cost, and is convenient for field operation.

Detailed ways

As shown in FIGS. 1 to 8 , the hanging bottle of the present invention mainly includes a bottle body 1 , a drawstring 2 and a baffle 3 , and the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3 , the bottle body 1 is the main body part of the present invention, and the bottle body may be a plastic bottle or a glass bottle. The bottle body is an opaque bottle to avoid the Drosophila pupae being exposed to the sun. The lower part of the bottle body is in the shape of a cuboid, and the corners are rounded; the upper part of the bottle body is a conical structure, the upper part of the bottle body is provided with a bottle mouth, and a bottle cap 11 is installed on the bottle mouth through threads.

A pull rope 2 is tied on the bottle mouth, the first end of the pull rope is tied with the bottle mouth, and the second end of the pull rope is tied with a rope loop 21, so as to realize the suspension of the bottle body. The drawstring can also be tied or fixed on the outer wall of the bottle, and the rope loop is wrapped around the branches of the crops 4 . A hook can also be provided at the second end of the pulling rope, and the bottle body can be hung on the field crops through the hook.

As shown in FIG. 4 , square holes 12 are respectively provided on the four sides of the bottle body, and baffles 3 are installed in the square holes. The baffle is a rectangular plate, the baffle is a plastic part, and the first end of the baffle is arranged in the square hole and is hingedly connected with the bottle body. As shown in Figures 5 and 6, a side bar 31 is provided at the second end of the baffle plate, and a slit 32 is arranged on the side bar. Cut out. A limit bar 33 is fixed on the end face of the second end of the baffle, and a limit groove that contacts the limit bar is provided on the inner wall of the square hole. When the limit bar is placed in the limit groove, the baffle and the bottle are opposite to each other. fixed. Rounded corners are provided at the edge of the limit bar, so that the limit bar can smoothly enter the limit groove. At this time, the baffle is slightly deformed to squeeze the limit bar into the limit slot. A damping member is arranged between the baffle plate and the inner wall of the square hole, so that the baffle plate can be positioned at any position relative to the bottle body. At least one climbing rod 34 is provided on the baffle. As shown in FIG. 5 , the climbing rod 34 includes a first straight rod 341 and a second straight rod 342 , and the first end of the first straight rod is connected to the hinge shaft 35 with the The baffle is hingedly connected, and the first end of the second straight rod is hingedly connected with the second end of the first straight rod through the hinge shaft. In this way, the entire climbing rod can be folded, and the hinge shaft can rotate the second straight rod, so that the first straight rod and the second straight rod can overlap up and down, and the length of the climbing rod is the smallest; The straight poles are staggered so that the climbing poles are unfolded, and the length of the climbing poles is maximum at this time. As shown in FIG. 7 , when in use, the first straight rod is turned relative to the baffle, and the second straight rod is flipped relative to the first straight rod, so that the climbing rod is pulled out from the baffle and unfolded.

When in use, as shown in Figure 8, hang the bottle body on the crop; remove the baffle from the square hole, and then open the bottle from the side; then remove the climbing rod from the baffle and unfold, at this time the bottle body The fruit fly pupae will climb out of the bottle along the baffle and climbing rod to the crop. Parasitic wasps lay eggs in Drosophila pupae, thereby promoting the reproduction of parasitic wasps and inhibiting the growth and reproduction of Drosophila pupae. According to needs, the number of open baffles and the unfolded length of the climbing rod can be selected, so as to meet the needs of the fruit fly pupae to climb out.

The method for using the parasitic wasp suspension bottle for controlling fruit flies includes the following steps:

(1) the fruit fly pupa is loaded into the bottle body, and the bottle cap is screwed up and the baffle is closed;

(2) hanging the bottle body on the field crops;

(3) Open the flap, and unfold the climbing pole so that the climbing pole is in contact with the crop.
