Embodiment 1

[0026] Such as figure 1 , including beehive 1, nest foundation 2, two feeding ports 3a, 3b, honeybee introduction port 4, wire mesh groove 5, stainless steel wire mesh 6, conical pipe 7a, 7b and rubber stopper 8 for feeding, Wherein, the honeybee introduction port 4 and two feeding ports 3a, 3b are arranged on the top of the beehive 1, and the base 2 is arranged on the inner bottom surface and the two inner surfaces of the beehive, and the outer edges of the two sides near the front side are provided with concave holes. Groove 5, stainless steel wire mesh 6 is placed on the groove 5, can be drawn out and advanced from the groove flexibly.

[0027] Such as figure 2 Shown, nest foundation 2 is the wax board that is made by beeswax, and both sides are all neatly arranged with the room eye that shape is pentagon, for better implementing the present invention, described nest foundation area basically covers the inner bottom surface and the inner bottom surface of beehive. sides....

Embodiment 2

[0038] Embodiment 2: Honeybee reference substance experiment.

[0039] The bee acute oral toxicity test is used to determine the oral toxicity of the test substance to bees. Under the prescribed conditions, the bees are allowed to ingest different doses of the test substance medicinal honey through the oral route, and the dose of the test substance that causes 50% of the bees to die is determined. In this experiment, the acute oral toxicity of the reference substance dimethoate to bees was determined to determine whether the experimental device, experimental method and conditions meet the requirements.

[0040] 1 Materials and methods

[0041] 1.1 Test organisms

[0042] Italian honey bees (Apis mellifera L.), adult worker bees, were provided by Nanjing Jiangning United Beekeeping General Farm. During the experiment, healthy bees of the same size were selected and randomly assigned to each treatment or control group.

[0043] 1.2 Experimental conditions

Abstract

The invention discloses a bee acute oral toxicity experimental apparatus. The bee acute oral toxicity experimental apparatus comprises a bee cage, a bee entrance and two feed openings are formed in the top of the bee cage, the two feed openings are respectively provided with a conical tube capable of being inserted into the bee cage to be fixed, the bee entrance is provided with a conical rubber stopper capable of being inserted into the bee cage to be fixed, one side of the bee cage is open and provided with a detachable stainless steel wire mesh, a comb foundation is arranged in the bee cage, and small vent holes are formed in the bottom face of the bee cage. The bee acute oral toxicity experimental apparatus is easy and convenient to use and high in operability. Materials used for the experimental apparatus are easy to obtain, and the experimental apparatus is simple in structure and convenient to manufacture and maintain.

Description

technical field [0001] The invention relates to a toxicity test device, in particular to a bee acute oral toxicity test device. Background technique [0002] Bees belong to the order Hymenoptera and Apiaceae, and are one of the insect groups beneficial to human beings. They not only gather flowers to make honey, but also impart pollen, which has important economic and social values. Bees collect flowers and pollinate in the field, so it is difficult to avoid exposure to pesticides, or directly ingest pesticide residues in plants or water through oral route, or be exposed to pesticides through body surface contact. When bees are exposed to pesticides that are highly toxic to bees, it can cause the death of individual bees, which can eventually lead to changes in the entire population. According to research, there is a close relationship between colony collapse disorder (colony collapse disorder), which has received more and more attention in recent years, and the extensive u...
