Simple investigation method of earth surface insect diversity

Abstract

The invention provides a simple investigation method of earth surface insect diversity. The method comprises the following steps that multiple base plates with the same specification are chosen, the upper surface of each base plate is evenly coated with a glue to be prepared into an insect gluing plate; sampling points are set in a field which needs to be surveyed according to a five-point sampling method, and four insect gluing plates are placed on each sampling point; the insect gluing plates on all sampling points are recycled every week, new insect gluing plates are replaced, and then the insect types and number on the recovered insect gluing plates are counted; the continuous counting cycle is 15-20 weeks. When the number of the earth surface insects is surveyed through the simple investigation method of the earth surface insect diversity, since the glue on the insect gluing plates can firmly glue the insects, thus the problem can be avoided that sampling is inaccurate caused when the insects are prevented from flying away or plunging under the ground. The simple investigation method of the earth surface insect diversity is easy and convenient to operate, the adopted material is easy to obtain, and the surveyed data is accurate at the same time.

Description

Technical field [0001] The invention relates to a method for investigating insects, in particular to a simple method for investigating the diversity of surface insects. Background technique [0002] Insects on the ground may have no wings, or have wings but are not good at flying, or they can only crawl and jump. Some flying insects also live on the ground during their larval and pupal stages. Some parasitic insects and insects that feed exclusively on decaying animals and plants (including insects that live indoors with humans) also mostly live on the surface. Insects active on the surface account for the vast majority of all insect species, so the diversity of surface insects is an important part of insect diversity. At present, the commonly used method for investigating the diversity of surface insects is the surface trap method: 4 traps are dug at each test point on the surface, each trap is 5-10cm deep and 10cm long and wide. When insects pass by the trap, they fall into t...

Problems solved by technology

The shortcomings of this method are: 1. After insects are transferred into the trap, those with wings can fly out, resulting in inaccurate sampling; 2. After insects are transferred into the trap, some insects can drill into the soil and be lost, which also causes sampling errors. Inaccurate
