AI Technical Summary

Benefits of technology

This patented technology allows people working on creatures like litchels or turtles to grow bigger without having to use living animals such as fishes or cows instead of food sources. By mixing these feeds together they become easier to produce because all parts work well together rather than being separated from one another. Additionally, this new technique helps prevent contamination by controlling different stages during growth while also allowing for efficient mass production at low costs.

Problems solved by technology

This patented technical solution involves developing new types of lacelightweed that may provide better nutritional value compared to traditional methods such as pepper plants. These weaves contain various chemical substances from different sources including carboxylic acides, amino acid analogues, flavonoids, alkaloids, terpenes, hydrocarbones, fatty alcohols, sterins, chlorophyllanes, phthaleutaneous compounds, polysaccharide gumets, proteases, lycopene diodesammonium salt crystal structures, enzymes involved in photosynthesis processes, and others.

Embodiment 1

[0034] The influence of embodiment 1 three kinds of feeds on the growth and development of the large lacewing

[0035] 1 Materials and methods

[0036] The artificial eggs of Trichogramma pupae, rice moth eggs and aphids were used as food, and the newly hatched lacewing larvae were reared in a glass feeding tube (500ml) with paper strips as spacers. Add enough feed every day to pupate cocoons in time every day after pupation. 5 cylinders were raised for each treatment. Observe and record the larval duration, pupal duration, pupation rate and eclosion rate every day. After 3 days of cocooning, the pupae were weighed electronically. Observe and record the survival of each insect state.

[0037] During the experiment, the temperature was 27±1℃, the photoperiod was L:D=14:10, and the relative humidity was 70±5%.

[0038] 2 Results and Analysis

[0039] 2.1 Effects of different feed treatments on the growth and development of the lacewing

[0040] It can be seen from Table 1...

Embodiment 2

[0052] The hatching of embodiment 2 big lacewing ovum and cold storage condition

[0053] 1 Materials and methods

[0054] 1.1 The influence of temperature and humidity

[0055] The treatment temperature gradient was set at 15°C, 20°C, 25°C, and 30°C, and the humidity was set at 35% and 70%. Collect fresh eggs produced by the lacewing within 12 hours, pack 20 eggs in each finger tube, and use 5 tubes for each temperature gradient. Repeat 3 times. Observe the development of the eggs every day, and observe every 2 hours when the surface of the eggs turns black and hatches quickly. Record the developmental period and hatching status of eggs in each treatment.

[0056] 1.2 Cold storage of Lacewing eggs

[0057] Eggs developed at 27°C to different stages were collected: within 8 hours after birth, 24-32 hours after birth, and 48-56 hours after birth, and packed into finger tubes, 80 eggs per tube. According to the starting point temperature of egg development, 4 temperature g...

Embodiment 3

[0080] Embodiment 3 stocking density and the influence of temperature on cannibalism

[0081] 1 Materials and methods

[0082] 1.1 Stocking density

[0083] Raise the 1st instar larvae of lacewings in a 15×10 (diameter*height) round box, with a density of 30, 60, 90, 120, and 150 per box, isolate them with a 5mm wide paper strip, repeat 3 times, and feed enough of aphids. Observe and record the pupation (cocooning) rate of each treatment. And with a single independent feeding as a control. During the test, the temperature was 27°C, the photoperiod was L:D=14:10, and the relative humidity was 70±5%.

[0084] 1.2 Breeding temperature

[0085] At 20°C, 25°C, and 30°C, 50 newly hatched larvae were reared in each box. 3 repetitions. 50 larvae were raised in each cylinder, and the pupation (cocooning) rate of each treatment was observed and recorded. And with a single independent feeding as a control. During the test, the photoperiod was L:D=14:10, and the relative humidity...

Abstract

The invention relates to a method for propagating chrysopa pallens larvae through rice moth eggs.The method includes the two steps of obtaining the rice moth eggs and breeding chrysopa pallens.Chrysopa pallens breeding includes the steps of adult breeding, breeding in the egg stage, free-range breeding of the larvae, cocoon harvesting in the pupal stage, eclosion of adults, refrigerating and packaging of products, and the like.Research is conducted from all breeding key technical links such as processing of the rice moth eggs, collection and storage of chrysopa pallens eggs, free-range breeding of the chrysopa pallens larvae, pupation and cocoon harvesting, development and eclosion and refrigerating of products in different insect states, and scientific bases are provided for large-scale chrysopa pallens propagation through the rice moth eggs.
