Acanthoscelides obtectus standard sample and preparation method thereof

Abstract

The invention relates to the field of plant quarantine, especially relates to an acanthoscelides obtectus standard sample, and additionally relates to a preparation method of the standard sample. In the acanthoscelides obtectus standard sample, a confirmed acanthoscelides obtectus body is embedded in a resin with one acanthoscelides obtectus per resin. The standard sample of the invention eliminates result differences caused by the using of different references in laboratories, ensures the traceability of identification results, plays an important role in the guarantee of the accuracy and reliability of acanthoscelides obtectus morphology identification results, and has important significance for gap filling in standard sample development for plant quarantine at home and abroad, and standardization of insect morphology identification work in our country.

Description

Problems solved by technology

However, at present, standard samples are only widely used in metallurgy, non-ferrous metals, chemistry, food additives, etc., the research carried out is relatively in-depth, and the technology has matured, but it is still blank in the field of plant quarantine, and there is no research on insects and insects. In the study of standard samples, many laboratories still use traditional methods in the identification of insect morphology, comparing pictures or specimens preserved in the laboratory for identification, and these specimens come from different sources, and specimens preserved in different laboratories sometimes have morphological differences. Large variances, even wrong specimens

In this way, due to the differences in reference substances, there are great differences and incomparability in the identification results between different laboratories, and the identification results cannot be traced.
