Problems solved by technology

[0003] The purpose of the present invention is to provide a fast and effective way to obtain a large number of experimental mites without damage and cleanness (with little or no impurities), so as to solve the problem in the prior art that collecting mites is time-consuming and laborious, and that the damage to experimental mites affects the final research results.

Embodiment 1

[0018] For the collection of female adult mites of A. ellipsoidus raised in the laboratory, the samples were poured into a 140-mesh sampling sieve for preliminary screening.

[0019] Evenly spread the samples left in the sieve after preliminary screening on a clean organic plastic board, turn over the organic plastic board after standing for 5 minutes, and turn the remaining samples upside down on a 220-mesh sampling sieve after the feed debris falls off On the top, lightly tap with a small wooden stick, and the sample containing acaroidophilus ellipticum and a small amount of feed debris falls into the sieve. After standing for 2 minutes, the 220-mesh sampling sieve containing the sample is inverted on the feeding On the container, recycle the rest of the mite state of A. ellipsoidus. In the end, the 220-mesh sieve left all female adult mites of A. ellipsoidus. The mites in the 220-mesh sieve were collected with a finger tube filled with 70% ethanol for subsequent experiment...

Embodiment 2

[0021] For the collection of adult female tyrophagous mite raised in the laboratory, the sample was poured into a 180-mesh sampling sieve for preliminary screening.

[0022] Evenly spread the samples left in the sieve after preliminary screening on a clean organic plastic board, turn over the organic plastic board after standing for 5 minutes, and turn the remaining samples upside down on a 220-mesh sampling sieve after the feed debris falls off On the top, lightly tap with a small wooden stick, and the sample containing Tyrophagous mite and a small amount of feed debris falls into the sieve. After standing for 2 minutes, put the 220-mesh sampling sieve containing the sample upside down on the feeder of Typhophagous mite , and recycle the remaining tyrophagous mite in mite state. Finally, the 220-mesh sieve left all female adult mite of Tyrophagous mite. The mites in the 220-mesh sieve were collected with a finger tube filled with 70% ethanol for subsequent experimental resea...

Abstract

The invention provides a method for quickly separating mites from feed. The method comprises the following steps: taking a proper quantity of samples from which the mites need to be collected, and adopting a sample screen of different apertures according to the sizes of the mites to carry out preliminary screening; evenly spreading the samples which are subjected to the preliminary screening on a plastic plate, overturning the plastic plate after standby, and enabling a great quantity of mites and a small quantity of feed fragments to be adsorbed on the plastic plate; reversely buckling the plastic plate attached to the samples subjected to preliminary processing on a thinner sample screen, beating with hands or a small stick to cause all samples to fall into the sample screen, inverting the sample screen after the standby, so that residual feed falls and the required mites are left in the screen almost without the feed fragments.

Description

technical field [0001] The invention relates to a method for separating and purifying mites from feed, in particular to a method for rapidly obtaining a large amount of mites required for experimental research by separating experimentally cultivated mites from feed. Background technique [0002] A large number of experimental samples are often required in the analysis or research of mite biological experiments. However, although there are a large number of mites raised in the laboratory, they are mixed with the feed for raising the mites, and it is often impossible to effectively collect enough experimental mites. At present, these mites are usually obtained by manually separating the debris. It is small and cumbersome to operate, and when using a capture tool, such as a brush, it is easy to damage the mite sample and the efficiency is low, which is not conducive to the next analysis experiment. . Therefore, in view of the above factors, there is an urgent need for a metho...
