In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 and 2, in one embodiment, an insecticide efficacy testing box 10 is provided, which includes a bottom plate 110, side plates 130, and a top plate 120. The number of the side plates 130 is at least three, the bottom plate 110 and the top plate 120 are arranged at intervals, and the side plates 130 are arranged between the bottom plate 110 and the top plate 120. The bottom plate 110 and the top plate 120 are provided with first stepped grooves 111. The bottom end of the side plate 130 and the top end of the side plate 130 are provided with a first step block 112. The first step block 112 can be inserted into the first step groove 111, such that the bottom plate 110, the side plate 130 and the top plate 120 enclose a closed cavity 140.

When the pesticide effect testing box 10 of the embodiment is used, the first step block 112 and the first step groove 111 are in inserted fit, so that the side plate 130, the top plate 120 and the bottom plate 110 enclose a closed cavity 140, and a pesticide to be tested and a test insect are placed in the closed cavity 140, so that the pesticide effect can be tested. In the pesticide effect test process, through the insertion and matching of the first step block 112 and the first step groove 111, the number of matching surfaces at the insertion positions of the bottom plate 110 and the side plate 130 and the insertion positions of the side plate 130 and the top plate 120 are increased, and further the contact area between the bottom plate 110 and the side plate 130 and the contact area between the side plate 130 and the top plate 120 are increased, so that the sealing effect between the bottom plate 110 and the side plate 130 and between the side plate 130 and the top plate 120 are enhanced, the volatilized pesticide is prevented from leaking from the closed cavity 140, the concentration of the pesticide in the closed cavity 140 is ensured, and the accuracy of the test result is improved. Meanwhile, when the pesticide effect testing box 10 is transported or left unused, the first step blocks 112 and the first step grooves 111 can be used for being matched in an inserted manner, so that the pesticide effect testing box 10 can be disassembled into the independent top plate 120, the independent side plates 130 and the independent bottom plate 110, the top plate 120, the independent side plates 130 and the independent bottom plate 110 can be stacked, and the transportation space and the storage space of the pesticide effect testing box 10 are reduced. In addition, by detaching the pesticide effect testing box 10 into the independent top plate 120, side plate 130 and bottom plate 110, it is not only convenient for the experimenter to move the pesticide effect testing box 10, but also convenient for the experimenter to clean the pesticide effect testing box 10.

The bottom plate 110, the side plate 130, or the top plate 120 may be made of glass, plastic, or the like.

The shape of the pesticide effect testing box 10 can be flexibly designed or adjusted according to actual needs, and only one closed cavity 140 needs to be formed. For example, when the pesticide effect testing box 10 is designed as a triangular prism, the shape of the top plate 120 and the bottom plate 110 is correspondingly set to be triangular, the number of the side plates 130 is three, and the side plates 130, the top plate 120 and the bottom plate 110 are assembled into a triangular prism with a closed cavity through the insertion fit of the first step blocks 112 and the first step grooves 111. When the pesticide effect testing box 10 is designed to be a cube, the shape of the top plate 120 and the shape of the bottom plate 110 are correspondingly set to be a square, the number of the side plates 130 is four, and the side plates 130, the top plate 120 and the bottom plate 110 are assembled to form a cube with a closed cavity through the insertion and matching of the first step blocks 112 and the first step grooves 111.

Alternatively, the pesticide efficacy test kit 10 is designed as a cube. Thus, in the assembling process of the pesticide effect testing box 10, the bottom plate 110 and the top plate 120 have the same shape and size, and all the side plates 130 have the same shape and size, so that the pesticide effect testing box 10 can be conveniently assembled by experimenters, and meanwhile, the assembling time of the pesticide effect testing box 10 is shortened.

Alternatively, the side length of the pesticide effect test box 10 can be designed or adjusted according to actual needs. For example, the side length of the pesticide effect test chamber 10 is set to 60cm to 80cm, preferably 70 cm.

Alternatively, as shown in fig. 2 and 3, the first stepped groove 111 has a first groove 1111 and a second groove 1112 that communicate with each other. The first step block 112 includes a first protrusion 1121 and a second protrusion 1122 connected to each other. The width of the first groove 1111 is smaller than the width of the second groove 1112. The width of the first bump 1121 is smaller than the width of the second bump 1122. The first protrusion 1121 is inserted into the first recess 1111. The second protrusion 1122 is inserted into the second groove 1112. Thus, in the assembling process of the pesticide effect testing box, the first bump penetrates through the second groove and is inserted into the first groove, the second bump is also inserted into the second groove, so that the side wall of the first bump 1121 is in inserting fit with the side wall of the first groove 1111, and the side wall of the second bump 1122 is in inserting fit with the side wall of the second groove 1112, thereby increasing the number of matching surfaces at the inserting positions of the bottom plate 110 and the side plate 130 and the top plate 120, increasing the contact area between the bottom plate 110 and the side plate 130 and between the side plate 130 and the top plate 120, enhancing the sealing effect between the bottom plate 110 and the side plate 130 and between the top plate 120, further preventing the volatilized pesticide from leaking from the closed cavity 140, ensuring the concentration of the pesticide in the closed cavity 140, and improving the accuracy of the test result.
