Abstract

The invention discloses a preservation method for golden cicada eggs. The preservation method comprises the following steps: (1) preparation of a sand pit; (2) sterilization of branches with the golden cicada eggs; (3) sand disinfection; (4) burying of the branches in the sand pit; (5) sealing and covering of the sand pit; and (6) unsealing of the sand pit. According to the method, the branches with the golden cicada eggs are deeply buried in sand, so the golden cicada eggs are not prone to water loss and high in plumpness, and the golden cicada eggs cannot be extruded and damaged due to xylemshrinkage caused by water loss of the branches, so the preservation effect of the golden cicada eggs is good; sand fills gaps among the branches, and the activity range of pests in the branches withthe golden cicada eggs is limited, so diseases and pests are prevented and controlled, and the health rate of the golden cicada eggs is increased; frequent water spraying operation on the branches with the golden cicada eggs is not needed, so labor is saved; and the development progress of the golden cicada eggs can be manually controlled, so artificial breeding of golden cicadas can be flexibly carried out.

Description

technical field [0001] The invention relates to a method for preserving eggs of cicadas, in particular to a method for preserving eggs of cicadas which can improve the fullness and health rate of eggs of cicadas. Background technique [0002] The golden cicada (Cryptotympana atrata) is an insect class of the animal kingdom, belonging to the Hemiptera Tetrididae, and is distributed in northern Jiangsu, northern Anhui, Shandong, Henan and other places in my country. Cicadas go through three stages in their life: egg stage, nymph stage and adult stage, and it usually takes 3-5 years or even longer to complete one generation. Adults begin to lay their eggs in the 1-2 year old branches of trees in late June each year, and the eggs produced in that year will not hatch. Under natural conditions, the eggs begin to hatch into nymphs in June of the next year. The nymphs are in the stage between eggs and adults. The newly hatched nymphs are small and delicate, and the whole body is mi...
