Problems solved by technology

The existing bat moth breeding technology does not predict the hatching rate of bat moth eggs, but first places the bat moth eggs directly in the culture environment to hatch, and then measures the hatching rate, because eggs of different spawning dates and different species of bat moths The hatching rate of eggs is different. When feeding in the same space, the population density of insects in the same feeding space will be different, resulting in a waste of space and feed, which is not conducive to uniform feeding management.

Embodiment 1

[0031] A method for predicting the hatchability of bat moth eggs, comprising the steps of:

[0032] In step (1), the eggs of a certain oviposition date of the manta moth to be determined are washed with clean water, dried, and 200 eggs are sampled;

[0033] Step (2), select multiple petri dishes of the same size, the diameter of the petri dish is 8cm, spread filter paper on the bottom of the petri dish, and pour 500ml of cold boiled water into each petri dish;

[0034] Step (3), put the eggs sampled in step (1) into a petri dish for incubation, the incubation temperature is 11°C; after sampling, put the remaining eggs into other petri dishes at the same density for incubation, the hatching temperature is higher than that obtained by sampling The hatching temperature of the eggs is 2°C lower; if the hatching temperature is lower than the ambient temperature, it needs to be hatched in a refrigerated artificial climate box or a cold room.

[0035] Step (4), during the hatching p...

Embodiment 2

[0041] A method for predicting the hatchability of bat moth eggs, comprising the steps of:

[0042] In step (1), the eggs of the bat moth to be determined on multiple oviposition dates are washed with water and dried, and 50-1000 eggs are sampled on each date;

[0043] Step (2), select multiple petri dishes of the same size, the diameter of the petri dish is 5cm, spread filter paper on the bottom of the petri dish, and pour 100ml of cold boiled water into each petri dish;

[0044] In step (3), the eggs sampled in step (1) were placed in different petri dishes for incubation according to the spawning date, and the eggs with the same spawning date were placed in the same petri dish for incubation, and the incubation temperature was 16°C; after sampling The remaining eggs are divided into dishes according to the same density according to the spawning date, and put into other petri dishes for incubation. The incubation temperature is 3°C lower than that of the eggs obtained by sam...

Embodiment 3

[0051] A method for predicting the hatchability of bat moth eggs, comprising the steps of:

[0052] In step (1), the eggs of multiple oviposition dates of the yunnanensis moth and the white horse moth to be determined are washed with clean water and dried, and 1000 eggs of each species are sampled for each date;

[0053] Step (2), select multiple petri dishes of the same size, the diameter of the petri dish is 10cm, spread filter paper on the bottom of the petri dish, and pour 1000ml of cold boiled water into each petri dish;

[0054] In step (3), the eggs sampled in step (1) are divided into plates according to the type and spawning date for incubation. Eggs of the same type and the same spawning date are placed in the same petri dish for incubation, and the incubation temperature is 17°C; after sampling, the remaining According to the same density, the eggs were divided into different dishes according to the type and date of spawning, and placed in other petri dishes for inc...

Abstract

The invention relates to a prediction method for a bat moth hatching rate. The method is that to-be-measured eggs are cleaned and dried and then sampled; a plurality of culture dishes having the same size are selected; a piece of filter paper is laid on the bottom of the culture dish and then cold boiled water is injected; a sampled egg is placed into one culture dish for hatching; the rest eggs are hatched at the same density; the hatching temperature is 2 to 10 DEG C lower than hatching temperature of the sampled egg; the egg is swept once via a clean brush pen; the egg is swept for times to keep the filter paper humid; microscopic examination is conducted three days after the sampled egg hatches larva; and the hatching rate can be calculated. With hatching temperature differences, hatching rate of each batch of to-be-placed bat moth eggs can be predicted before the bat moth eggs are placed into a culture field. Egg stocking amount in specific culturing space can be determined according to the predicted hatching rate, so the same culturing space can have same or similar population density; the culturing space can be intensively utilized, so culturing space, material and human resource cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of insect breeding, and in particular relates to a method for predicting the hatching rate of bat moth eggs. Background technique [0002] Insects of the genus Manta ( Hepialus spp. ) is a rare Chinese medicine Cordyceps sinensis ( Ophiocordyceps sinensis ) host, realizing the large-scale breeding of bat moths is the key link to realize the artificial cultivation of Cordyceps sinensis. The existing bat moth breeding technology does not predict the hatching rate of bat moth eggs, but first places the bat moth eggs directly in the culture environment to hatch, and then measures the hatching rate, because eggs of different spawning dates and different species of bat moths Egg hatching rates are different, and when the same space is used for feeding, the population density of the same feeding space will be different, resulting in a waste of space and feed, which is not conducive to uniform feeding and managem...
