A beetle trapping device for open-air is traped

Technical Field

The utility model relates to a light traps insect technical field, concretely relates to a step first worm trapping device for open-air is traped.

Background

The Artocarpus family belongs to the suborder carnivora of Coleoptera, the third major family of Coleoptera, and 29000 species of insects are known in the world. The beetles (insects of the family Stephaniae) are not good in flying, have the property of inhabitation, mostly move on the ground surface, are agile in action, like moist soil or places close to water sources, are generally hidden under trees, deciduous leaf layers, tree skins, mosses or caves in the daytime, and have phototaxis and false death phenomena. The beetles are mainly predatory and play an important role in maintaining ecological balance and killing pests, for example, the golden star beetles heavily prey on harmful mollusks such as lepidoptera larvae and snails which are agricultural pests. The quantity and the species of the beetles show the quality of forests, particularly protoforests to some extent, so that the beetles are important to be used as biodiversity evaluation indexes. At present, the wild beetles are trapped by a trapping device mainly according to phototaxis of the beetles.

For example, chinese patent publication No. CN110679573A discloses a field living body trapping device for terrestrial arthropods; this open-air live body trapping device includes: the light source inducing unit is provided with a containing cavity, and a light source is arranged in the containing cavity; the light source is used for emitting attraction light capable of attracting the arthropods on the ground; a collecting and installing unit connected by installation and buried under the soil surface for collecting living body ground arthropods; the collecting and mounting unit comprises a conveying assembly and a collecting assembly, wherein the top of the conveying assembly is detachably connected with the light source inducing unit, and the collecting assembly is detachably connected to the bottom of the conveying assembly; the conveying component is provided with a funnel-shaped conveying channel which is communicated with the containing cavity of the light source inducing unit and is wide at the top and narrow at the bottom; the collection assembly has a collection bin in communication with the transfer passage.

The wild living body trapping device in the prior scheme can also be used for trapping the beetles and comprises a containing cavity (of a trapping cylinder), a light source component (emitting attraction light capable of attracting the beetles) and a collecting bin (when in use, the collecting bin is partially buried under the soil surface for installation, when in use, the beetle trapping device in the prior scheme attracts the beetles through the light source component, the phototropism of the beetles enables the beetles to climb into the containing cavity (of the trapping cylinder) and slide into the collecting bin to complete the collection, the prior beetle trapping device can effectively attract and collect the collected beetles into the beetle collecting bin, but the prior beetle trapping device has the problems that all the collected beetles are stored in the same collecting bin and the beetles are predatory insects in the actual use process, it has certain aggressivity, and when collecting the step beetle in the storehouse too much, they will fight each other for the step beetle in the collection storehouse is very easy because of fighting and is disabled, thereby can not well be makeed into the step beetle sample, leads to the trapping effect of step beetle trapping apparatus not good.

SUMMERY OF THE UTILITY MODEL

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a step beetle trapping device that can effectively reduce the mutual probability of fighting of step beetle to can assist the integrality of protection step beetle sample, thereby can promote trapping device's effect of traping.
