Embodiment 1

[0014] Example 1 Effects of Different Disinfection Time Lengths on the Growth and Development of Bean Hornmoth Eggs

[0015] Hydrochloric acid solution (mass fraction 38%) and formaldehyde solution (mass fraction 37%) are mixed in equal volumes and then diluted with water at a volume ratio of 1:10 to form a disinfectant. After the ovum in the constant temperature incubator is cultivated to the age of 5 days, it is put into a plastic net bag by 30, and the mouth of the net is fastened to prevent the eggs from spilling. The disinfection time is divided into 5 gradients of 10min, 20min, 30min, 40min and 50min. Pour 400ml of disinfectant solution into a 500ml beaker, immerse the small mesh bag containing the eggs of bean hornworm, and treat 3 mesh bags in a gradient for each time length, and rinse the mesh bag with clean water immediately after the treatment, so as to rinse only with clean water The 3 mesh bags were used as the control group, which were wiped lightly with filter ...

Embodiment 2

[0022] Example 2 Effects of different disinfection durations on the growth and development of 25-day-old larvae of the horn moth

[0023] The 25-day-old larvae developed by the Manduca bean moth ovum after different durations of treatment in Example 1 are carried out to body length and body weight statistical analysis, and the impact of different disinfection durations on the 25-day-old larvae growth and development of Manduca beanus.

[0024] The results are shown in Table 2.

[0025] Table 2 Effects of disinfection time on the development of 25-day-old larvae

[0026]

[0027] It can be seen that the body length and body weight of the 25-day-old larvae of Hormus moth were relatively consistent after being treated for different lengths of time. After 30 minutes of treatment, the body length reaches the maximum, which is 8.02cm. The second is to process 40min and 10min respectively, and the body length is respectively 7.74cm and 7.66cm. The body length of 25-day-old larv...

Embodiment 3

[0028] The influence of embodiment 3 different disinfectants on the growth and development of bean hornworm eggs

[0029] Mix hydrochloric acid (mass fraction 38%), hydrogen peroxide (mass fraction 31%), August 4th disinfectant, and formaldehyde solution (mass fraction 37%) individually or in twos in equal volumes, and use distilled water as the solvent at a ratio of 1:5, 1 :10, 1:20 volume ratio dilution, thus forming different disinfectants. The composition and dilution ratio of each disinfectant are shown in Table 3.

[0030] Table 3 Composition and dilution ratio of each disinfectant

[0031]

[0032]

[0033] The method is as in Example 1. On the basis of disinfection for 30 minutes, different disinfectants are used to sterilize the eggs of Hornbus moth. Each disinfectant treats 3 mesh bags, and after the disinfection is completed, they are bagged in the community. Comparing the hatching rate and the survival rate difference of different day-old eggs after being t...

Abstract

The invention discloses a disinfectant for clanis bilineata tsingtauica eggs, belonging to the field of artificial breeding of resource insects. The disinfectant mainly comprises formaldehyde and hydrogen peroxide, wherein water is used as a solvent, and a volume ratio of the formaldehyde to the hydrogen peroxide to the water solvent is 0.5: 0.5: 10. The disinfectant can be obtained by dissolving 5 ml of the formaldehyde and 5 ml of the hydrogen peroxide into 100 ml of the water and conducting uniform stirring. According to the disinfectant for the clanis bilineata tsingtauica eggs in the invention, the clanis bilineata tsingtauica eggs can keep a relatively high hatching rate, and incubated larvae can also keep good growth and development at each instar. The disinfectant has a good disinfection effect on the clanis bilineata tsingtauica eggs, is low in manufacturing cost, simple in method and harmless to human bodies and the environment, and has important significance on efficient and standardized artificial breeding of clanis bilineata tsingtauica.

Description

technical field [0001] The invention belongs to the technical field of artificial cultivation of resource insects, and in particular relates to a disinfectant used for egg disinfection in the artificial cultivation process of the bean hornworm. Background technique [0002] Clanisbilineata tsingtauica Mell belongs to the genus Clanisbilineata tsingtauica Mell. Its larvae are commonly known as bean dan and bean worm. It is mainly distributed in the Huanghuai River Basin, Yangtze River Basin and South China. Its host plants mainly include soybean, kudzu vine, acacia and so on. Bean hornworm is an explosive pest in soybean production. Its larvae eat soybean leaves after the 5th instar. The light ones eat the leaves into nicks, and the severe ones can eat the bean plants into bare stalks, making them unable to set pods, which seriously affects soybeans. Yield. [0003] Soy bean has important edible value and medical value because of its high protein content, rich in essential ...
