Tetranychina harti feeder

Abstract

The invention relates to a Tetranychina harti feeder, which belongs to the technical field of entomology experiment. The feeder consists of an upper feeding chamber and a lower water pool. Safflower oxalis leaf isolated leaf with petiole is vertically planted into the feeder. The blade in which the mite is cultivated is hung in the feeding chamber. The petiole enters under the water level of the water pool through a petiole inserting pipe at the bottom of the feeding chamber. When the Tetranychina harti is fed by the feeder, the blade part of the safflower oxalis leaf is free from the preserving liquid, therefore the blade is difficult to yellow and mildew, the blade surface is dry, and the mite can freely move on the blade, and has natural living state. The feeding chamber is manufactured by a disposable plastic cup, a gauge and the like, and has the advantages of sealing property, permeability and light transmission; and the microenvironment in which the mite is cultivated is consistent with the set feeding condition. Each component of the feeder is easy to disassemble and assemble, therefore the microscopic observation and replacement of the blade are convenient.

Description

technical field [0001] The invention relates to a device for raising wood sorrel such as spider mites, and belongs to the technical field of insect (acari) science experiments. Background technique [0002] The sorrel-like spider mite is an understudied species of spider mite. In addition to feeding on the wild wood sorrel that can be used as traditional Chinese medicine, the mite also seriously harms the safflower wood sorrel used for landscaping. [0003] In the study of spider mites, it is often necessary to carry out individual feeding or quantitative feeding of the mite under set conditions, and to observe regularly during the feeding process. For the spider mites that mainly feed on the leaves of the host, they can be raised on leaves picked from the host plant (in vitro leaf method), or on leaves of living plants (in vivo leaf method). In the next case, certain methods or utensils should be adopted to keep the leaves fresh and prevent mites from escaping. In the lat...

Problems solved by technology

This method has the advantage of being more convenient to observe mites, but it also has many defects: (1) The surface humidity of the leaves is too high because they are close to the wet base, which makes the feet of spider mites easy to stick to dirt such as feces and hinders their activities, and makes the leaves It is easy to turn yellow and moldy and affect its lifespan and nutrition; (2) spider mites can only move on the upward leaf surface, and their positions are often unnatural; (3) due to the evaporation of moisture from the wet base, the leaf surface temperature is significantly lower than the ambient temperature (ie set temperature); (4) when using the water tray method, many spider mites will stray into the wet base material around the leaves and cause death or disappearance, especially species with long body thighs (such as wood sorrel such as spider mite )

The main advantage of this type of method is that there is generally no need to consider the problem of leaf preservation during the breeding process. The main disadvantage is that it is very inconvenient to carry out regular microscopic examination of the mites during the breeding process, and it is not suitable for wood sorrel (because the wood sorrel plant is very weak. , and the leaves are small)
