Problems solved by technology

Among the insect source feeds that are currently used more often, powder eggs, drone pupae, and Trichogramma pupae are not easy to obtain, while young Lepidoptera larvae are tiny, requiring a large amount of insect sources and a large amount of labor, and young ladybug larvae are not easy to obtain. Predation, resulting in high mortality of young larvae, and the current artificial feed feeding ladybugs do not lay eggs or lay few eggs in the adult stage

Embodiment 1

[0064] Embodiment 1: the preparation of chelonian ladybug artificial diet

[0065] 1. For the formula of artificial feed, see Table 1.

[0066] Table 1: Formula of artificial diet for ladybug

[0067]

[0068] 2. Preparation method:

[0069] (1) Raise armyworms with corn seedlings, take the fifth to sixth instar armyworms, and freeze them at -20°C.

[0070] (2) Put the frozen armyworm into the Joyoung cooking machine and smash it. Freeze again at -20°C, add aphids and crush again.

[0071] (3) Weigh the crushed armyworm powder, aphid powder, sucrose, yeast powder, honey, olive oil, methylparaben, potassium sorbate, ascorbic acid, vitamin B complex, Webster's salt, as group A substance;

[0072] (4) Add 0.37 g of agar to 25 ml of water, heat in a microwave oven for 40 seconds, shake well and continue heating for 40 seconds.

[0073] (5) Shake the agar water well, cool it down to about 60°C, mix the substances in group A, heat and stir evenly with a stirrer.

[0074] (...

Embodiment 2

[0076] Embodiment 2: the refrigeration processing method of aphid

[0077] The cold storage method of aphids is as follows: when aphids occur in large numbers, after collecting aphids, take a water bath at 55°C for 8 minutes, dry the water, and store at -20°C. After the aphids are bathed in water, it can effectively prevent the melanization of the hemolymph, thereby improving the fresh-keeping quality.

[0078] It is very critical to carry out water bath treatment to aphids before refrigeration treatment, for this reason, the present invention has carried out comparative test, and the results are shown in image 3 , image 3 Among them, A is the frozen P. pea after the water bath, B is the directly frozen P. pea without the water bath, and C is the radish aphid after being frozen in the water bath. Depend on image 3 It can be seen that after the water bath can effectively prevent the melanization reaction of aphid hemolymph, which is beneficial to freshness preservation an...

Embodiment 3

[0083] Embodiment 3: semi-artificial feed breeding mole-shaped ladybug

[0084] In this example, artificial feed and aphids were used to raise together. Firstly, the growth of larvae fed with frozen aphids at different ages, the survival rate of all ages of ladybugs fed with aphids at different ages, and the larval stages of ladybugs were investigated. Daily average and total amount of aphids. The results are shown in Table 3, Table 4 and Table 5 respectively.

[0085] Table 3: Fertility of larvae fed with frozen aphids at different ages

[0086]

[0087]

[0088] Table 4: Survival rate of ladybugs at different ages fed with aphids at different ages

[0089]

[0090] Table 5: The daily average and total amount of aphids in the larval stage of the mole beetle

[0091]

[0092] It can be seen from the above results that adding frozen aphids at the larval stage significantly shortened the developmental period and increased the survival rate compared with feeding wi...

Abstract

The invention discloses a method for breeding propylaea japonica with semi-artificial feed. A co-feeding mode with the artificial feed and aphids is adopted, and the artificial feed is made of, by weight, 20-30 parts of water, 3-5 parts of layers of oriental armyworm powder, 1-3 parts of yeast powder, 1-3 parts of honey, 1-2 parts of aphid powder, 0.5-1.5 parts of sucrose, 0.2-0.4 part of agar, 0.02-0.06 part of olive oil, 0.02-0.06 part of ascorbic acid, 0.02-0.04 part of methylparaben, 0.02-0.04 part of potassium sorbate, 0.04-0.06 part of Webster salt and 0.005-0.015 part of multivitamin B.By adopting the method, propylaea japonica can grow, develop and breed normally under the condition of saving 71.3% natural baits, so that the production cost is reduced, and large-scale breeding expansion of propylaea japonica is achieved.

Description

technical field [0001] The invention relates to the technical field of artificial breeding of natural enemy insects, in particular to a method for breeding mole-shaped ladybugs with semi-artificial feed. Background technique [0002] Propylaea japonica Thunberg belongs to the family Coccinellidae of Coleoptera (Coleoptera) and belongs to the genus Propylaea. It is widely distributed in most parts of my country, Japan, Russia, North Korea, Vietnam, and Bhutan. , India and other countries. The tortoise beetle can prey on a variety of aphids on various crops, vegetables, fruit trees and forest trees, eggs, young larvae (nymphs) of certain Lepidoptera and Homoptera insects, cotton spider mites, psyllid adults and black pine Pine aphids and other pests, among which aphids like to prey (Song Huiying et al., 1988; Pang Hong, 1991; Zeng Tao et al., 2000; Wang Shuhui et al., 2014; Chi Jiajia et al., 2017) Large, large number of eggs, strong adaptability, high temperature resistance, a...
