Description

Technical Field

[0001] The invention relates to a device for observing movement behavior of grain-storage insects in the field of grain storage. Background Art

[0002] Food is the primary need of the people. Grain is the material basis for the survival of human society. In the process of grain storage, grain loss is affected by many factors, among which grain storage pests are one of the important factors. According to data released by the State Administration of Grain in 2016, my country's national grain loss rate is as high as about 8%, among which pest losses are the most serious, accounting for 40% to 45%. Take the corn weevil as an example. As a major grain storage pest distributed worldwide, the insect infestation rate is as high as 70%, and the harm is extremely serious. Therefore, the discovery, identification, and prevention of grain storage pests have always been an important task in the field of national grain storage, and an important guarantee for reducing the quantity and quality losses in the grain storage process.

[0003] Understanding and mastering the behavioral characteristics and movement habits of stored-grain pests is one of the basic tasks for effective pest control. The discovery, identification, and control of stored-grain pests are based on scientific research on the occurrence and development laws of stored-grain pests. Stored-grain pests are tiny. For example, the maximum body length of corn weevils does not exceed 5 mm. The surface morphology and structure are complex and highly similar. It is quite difficult to study their behavioral characteristics even under laboratory conditions. In particular, there is a lack of effective technical means and devices for behavioral observation. Based on this, it is necessary to study a device for observing the behavior of stored-grain pests in a laboratory environment, which is used to study the behavioral characteristics and living habits of stored-grain insects, and ultimately achieve the purpose of understanding and mastering the occurrence and development laws of stored-grain insects, so as to carry out effective prevention and control. Summary of the invention

[0004] The object of the present invention is to provide a stored-grain insect movement behavior observation device which can observe the behavior of stored-grain insects.

[0005] To solve the above technical problems, the technical solutions in the present invention are as follows:

[0006] A device for observing the movement and behavior of stored-grain insects comprises an observation box and a cross slide, the cross slide having a longitudinal track extending in the longitudinal direction, a guide movable assembly having a transverse track on the longitudinal track, the device for observing the movement and behavior of stored-grain insects further comprising at least two partitions for dividing the observation box into a plurality of observation areas arranged in parallel in the transverse or longitudinal direction, a guide movable assembly having a movable seat on the transverse track, and an image acquisition device for observing the movement and behavior of insects in the corresponding observation area being arranged on the movable seat.

[0007] The image acquisition device is a camera.

[0008] The transverse track is driven by a transverse track motor to realize movement along the longitudinal track, and the moving seat is driven by a moving seat driving motor to realize movement along the transverse track.

[0009] The mobile seat is also provided with a radio microphone.

[0010] Each observation area is a strip structure extending in the horizontal direction or the vertical direction.

[0011] The observation box is a square box structure with a bottom wall and surrounding box walls. The box walls on opposite sides of the observation box are provided with partition card slots for corresponding partitions to be movably inserted in the up-and-down directions.

[0012] The grain storage insect movement behavior observation device also includes a host computer and an electronic temperature and humidity sensor for detecting the corresponding observation area. The host computer is connected to the electronic temperature and humidity sensor and the image acquisition device for sampling. The host computer is connected to the control of the transverse track motor and the moving seat drive motor through a motor controller.

[0013] The box wall of the observation box is made of transparent material, and an illumination luring lamp is arranged on the observation box.

[0021] Taking the example of inserting partitions in the slots of the left and right box walls, the use of the grain storage insect movement behavior observation device is explained as follows: insert partitions, which divide the observation box into multiple observation areas arranged in parallel along the longitudinal direction, each observation area is a strip structure extending in the transverse direction, and bait and insect samples are placed in each observation area. Since there are multiple observation areas, in order to obtain more data, the insect species, number, and generation in each observation area can be different, and the bait variety can also be different, so that the influence of bait variety on insect movement behavior can be observed; the influence of different insect species, different numbers, and different generations on insect behavior, check the environmental temperature and humidity data, on the one hand, confirm whether it meets the requirements of the test plan, and on the other hand, consider the influence of environmental temperature and humidity on insect movement behavior. Adjust the lighting and luring lights at different positions, adjust the color of the lighting and luring lights at the corresponding positions, and observe the influence of the position and color of the lighting and luring lights on the insect movement behavior. When the lighting and luring lights on the front and rear sides are on, the insect behavior in different partitions can also reflect the influence of the distance from the lighting and luring lights on the insect behavior. The transverse track movement can move the radio microphone and the industrial camera to the designated observation area. The mobile seat moves along the transverse track. The radio microphone and the industrial camera can cover the corresponding entire observation area from left to right. The industrial camera can replace the fixed focus / zoom lens as needed, can observe the actions of all insects in the corresponding observation area, can also observe a specific insect through zooming, can record video data, and can also take photos according to experimental needs. The radio microphone records the sound data during the experiment. After the experiment, the insects are collected, the bait is recovered, and the partition is taken out to clean the observation box. After the partition is taken out, the partition is easy to clean, and the observation box is also easy to clean. In other embodiments of the present invention: the structure of each partition may not be exactly the same. For example, the partition includes a transverse partition and a longitudinal partition. The longitudinal partition is provided with a partition slot for the transverse partition to be inserted. When in use, the transverse partition is inserted into the slot on the left and right side box walls, and the longitudinal partition is inserted into the slot on the front and rear side box walls, thereby forming a grid-shaped observation area; of course, the partition can also be a non-detachable structure fixed to the observation box by gluing.
