Wind tunnel for experimental research on behavior of small insects and ecology

Abstract

The invention belongs to the area of research on insect behavior and ecology, and discloses a wind tunnel for experimental research on behavior of small insects and ecology. The wind tunnel is provided with a wind tunnel main body frame, wherein the wind tunnel main body frame is provided with a wind tunnel top, a wind tunnel left outer wall, a wind tunnel right outer wall, a door, a wind tunnel front end, a wind tunnel back end and a wind tunnel bottom through bonding; both the wind tunnel front end and the wind tunnel back end are transparent nylon gauze; the wind tunnel back end is connected with a ventilation duct through bonding; a minicomputer host machine fan is fixedly arranged at the back end of the ventilation duct through screws and iron wires; and the minicomputer host machine fan is connected with a desktop computer stabilized voltage supply through conducting wires. The invention overcomes the defect that traditional large-size and medium-size wind tunnels need individual operation spaces and are difficult to manufacture in batches. The small-size wind tunnel for research on behavior of natural enemy insects and ecology is simple in structure, low in cost, easy to implement batch manufacturing and maintenance, small in size, convenient to carry and easy to regulate.

Description

technical field [0001] The invention belongs to the field of insect behavior and ecology research, in particular to a wind tunnel for experimental research on small insect behavior and ecology. Background technique [0002] Studying the prey-searching behavior of natural enemy insects in the laboratory can reveal the ability of natural enemies to control pests and the multi-level nutritional relationship between natural enemies-pests-plants and can be used to guide biological control of pests. Indoor insect behavior studies, however, are often carried out in petri dishes or small closed containers. Ignoring the complex environment under natural conditions may lead to a series of prey hunting behaviors of natural enemy insects that cannot be displayed more realistically. Because the wind tunnel has the characteristics of providing flowing air and a relatively large internal space that can accommodate the whole plant, it can provide a more natural experimental environment for...

AI Technical Summary

Problems solved by technology

At present, a single complex large and medium-sized wind tunnel has been used in China to study the behavior and ecology of natural enemy insects, but there is a lack of small insect behavior research wind tunnels that are simple in structure and can be mass-produced to facilitate multiple groups of repeated experiments.

[0003] To sum up, the problems existing in the existing technology are: the wind tunnels currently used at home and abroad for the study of insect behavior are high in cost, large in volume, and relatively complicated in technical parameters and structures.

There is a lack of small wind tunnels that are easy to mass-produce, low in cost, simple in structure and operation, and portable for studying insect behavior
