Trogoderma granarium standard sample and preparation method thereof

Abstract

The invention relates to the field of plant quarantine, and particularly relates to a Trogoderma granarium standard sample and the preparation method thereof. The Trogoderma granarium standard sample is prepared by inlaying a confirmed parent Trogoderma granarium in resin, wherein one Trogoderma granarium is inlaid in one piece of resin. The invention has the beneficial effect that aiming at the requirement of plant quarantine laboratory, the sample provided by the invention is the Trogoderma granarium standard sample which is inlaid in resin, and the resin material is liquid and has good fluidity, so that the resin material can fully cover the sample surface and is not soluble to water after being cured to form a film. The resin has extremely high transparency so that the fine structure of the standard sample inside can be observed conveniently. In addition, the resin has excellent flame-retardant, anti-aging, nontoxic, anti-oxidant, heat-resistant, insulated properties, thereby prolonging the validity of the Trogoderma granarium standard sample and lowering the cost of the Trogoderma granarium standard sample after the Trogoderma granarium standard sample is inlaid in the resin.

Description

technical field [0001] The invention relates to the field of plant quarantine, in particular to a standard sample of Trogoderma zea, and also relates to a preparation method thereof. Background technique [0002] Trogoderma cerevisiae ( Trogoderma granarium Everts) is an important pest in the list of quarantine pests in my country. Trogoderma gravy is very harmful and extremely difficult to control. It is also one of the important quarantine pests in the world. It can seriously harm a variety of plant products, such as wheat, barley, malt, oats, rye, corn, sorghum, rice, flour, peanuts, dried fruits, nuts and other cereals, beans, oil plants and other plant storage products. They also eat a variety of animal products, such as milk powder, fish meal, dried blood, cocoons, fur, silk and other animal products. Losses to cereals generally range from 5% to 30%, sometimes as high as 75%. In Southeast Asia, 4 to 5 generations occur in a year. Overwinter as larvae in cracks in ...

AI Technical Summary

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.
