Embodiment 1

[0054] Measure the diameter of the brown planthopper to be 3.8 mm. After connecting the computer and equipment, open the transparent top cover, put the brown planthopper between the base and the transparent top cover, and then close the transparent top cover. At this time, the brown planthopper can move freely in the limited space , when it is crawling on the bottom, due to the location of the receiver array, the insects will not block the infrared rays when crawling on the surface of the base, thus avoiding recording useless data, and when the insects take off, they will start to block the infrared rays, and the data will start Effective collection.

[0055] The collection and refresh rate is recorded every 0.01s. Input the status of each receiver into the computer, record the number of the receiver that has not received infrared rays, and map it to the already stored receiver array distribution map. According to the blocked reception Calculate the specific spatial position o...

Abstract

The invention discloses a device for measuring a flight trajectory of a flying insect without contact. The device comprises a receiver array, a transparent top cover and a base, the transparent top cover and the base are combined to form an enclosed space for insect activities, the base is provided with an infrared ray emitting source which can emit spherical infrared rays to the outside, and thereceiver array is uniformly and compactly installed at the inner side of the transparent top cover, can receive the infrared rays emitted by the infrared ray emitting source, and is connected with a signal processing device through a signal line; a method for measuring the flight trajectory of the flying insect without contact comprises the steps that in a dark environment, the infrared emitter isturned on, the position of a receiver which does not receive the infrared rays is determined, three-dimensional coordinate parameters of the insect are calculated by using a formula according to theposition of the receiver, and the flight trajectory of the insect is obtained by comparing a large number of coordinate parameters. By means of the device and method for measuring the flight trajectory of the flying insect without contact, the flight trajectory can be measured without causing any harm to the flying insect or by reducing human influence on the flying insect as much as possible.

Description

technical field [0001] The invention relates to the field of insect behavior, in particular to a measuring device and a measuring method for non-contact measuring flying insect flight trajectories. Background technique [0002] Many insects have orienteering behavior. A large number of studies on the orientation behavior of some social insects and migratory insects have preliminarily clarified that the sun, geomagnetic field, celestial bodies, wind, and ground markers may all be clues for the orientation of insects returning to their nests and migratory insects. But in the process of research, with the help of existing patents such as "a small insect directional flight simulation tracking device" (CN204272969U), it is very complicated to carry out experiments on individual smaller insects and the effect is not good. The patents all have a common shortcoming that the experimental device is in direct contact with the insect body, which affects the free flight of the insect. N...
