Description

Technical Field

[0001] The invention relates to the technical field of aquatic mesocosm experimental equipment, in particular to a device for collecting emerging insects. Background Art

[0002] Aquatic ecosystem refers to the ecosystem composed of aquatic biological communities and water environment. Still water ecosystems are usually a type of freshwater ecosystem, including freshwater lakes, ponds and reservoirs on land. Due to the limitations of scale and manufacturing difficulty, aquatic mesocosm technology often uses the method of simulating still water ecosystems to conduct ecotoxicology tests, among which the most widely used is the simulated pond ecosystem.

[0003] Aquatic mesocosm: An ecological simulation system built with aquatic ecosystem as the simulation object is an aquatic ecological simulation system. According to the scale, the aquatic ecological simulation system can be divided into microcosms and mesocosms. The water volume is greater than 15m 3 Or a water ecological simulation system with a stream length greater than 15m is called a mesocosm.

[0004] Eclosion: The process of an adult insect shedding its skin from its previous insect state is collectively called eclosion. The nymphs (larvae) of incomplete metamorphosis insects eclode to adults after the last molt. The pupae of holometabolous insects eclode to adults after molting.

[0005] Biomass refers to the total amount of organic matter (dry weight) (including the weight of food stored in organisms) that actually exists per unit area at a certain time, usually expressed in kg / m 2 or t / hm 2 express.

[0006] Biodiversity is a broad concept that describes the degree of diversity in nature, emphasizing species differences. Species diversity is an important characteristic of a community.

[0007] When comparing the species diversity characteristics of a community, the simplest method is to count the number of species in a certain group, which can be expressed as a species richness index or number of species.

[0008] In previous aquatic mesocosm experiments, it was difficult to count the emerging adults due to their irregular emergence period and large number of emerging adults. In addition, since there are many uncertain factors in field experiments, there will be certain errors in the statistics of the number and diversity of emerging adults, which will lead to errors in the survey results of the species and abundance of emerging insects. Summary of the invention

[0009] The purpose of the present invention is to provide a device for collecting emerged insects to solve the problems existing in the above-mentioned prior art, avoid interference from external factors, ensure the collection of emerged adults, facilitate the calculation of their biomass and clearly classify different types of emerged insects, and the device is relatively simple and light, does not need to be assembled before use, and is easy to use.

The inner diameter of the bottom entrance of the collection channel is 70 mm. The inner diameter of the collection container 9 is 100 mm. The collection container 9 is suspended directly below the collection channel through a connecting line 8, so that all the adult insects in the collection channel fall into the collection container 9. There is a gap between the collection container 9 and the bottom entrance of the collection channel to facilitate the emergence of insects. The insects then enter the collecting channel, which is fixed on the top of the confinement device 1 through a support frame 7. The top of the closed net 2 is fixed on the outer wall of the collecting channel, and the bottom of the closed net 2 is fixed on the outer wall of the confinement device 1.
