A kind of cryopreservation method of the eggs of A.

Abstract

The invention discloses a low-temperature preservation method for the eggs of A. chinensis A. chinensis, which comprises the following steps: taking the eggs laid on A. chinensis on the same day of A. chinensis, picking the leaves together, and placing them in a petri dish Use distilled water wet filter paper or 1% (m / v) agar medium at the bottom to keep the middle and bottom moist, seal the top with plastic wrap, and tie small holes for ventilation, and store A. The storage time of eggs is 5-7 days until the survival rate of each stage, adult fecundity and population growth are not affected. The invention solves the problem that the impact on the subsequent developmental stage, population and even the next generation of the A. chinensis can not be determined after the low-temperature preservation of the existing A. chinensis eggs. The invention can achieve the longest storage time for the eggs of the phalaenopsis beetle without affecting the subsequent development stage, population and even the next generation.

Description

technical field [0001] The invention relates to a method for low-temperature preservation of insect eggs, in particular to a method for low-temperature preservation of eggs of A. chinensis. Background technique [0002] With the rapid development of the global integration process, invasive organisms have increased significantly, threatening global ecological security and biological security. China is one of the countries most severely affected by alien biological invasions. Among the more than 600 identified invasive alien species, invasive plants account for nearly half. This has become one of the important factors restricting the economic development of our country. Alternanthera philoxeroides is a global malignant weed. It was introduced into my country in the 1930s and has now spread to more than 20 provinces, municipalities, and autonomous regions across the country. Ecological and other serious threats, resulting in annual economic losses of up to 600 million yuan. A...

Problems solved by technology

[0005] In order to overcome the defect that after the existing A. chinensis eggs are cryopreserved, it is impossible to determine the impact on the subsequent development stage, population and even the next generation of A. basilicum, the present invention provides a Low-temperature preservation method to achieve the longest preservation time for the eggs of A.
