Embodiment 1

[0033] like figure 1 and image 3 Shown, a kind of complete method of raising heterochromia ladybug comprises the steps:

[0034] 1) Seed selection: after the beginning of spring, collect Heterochromia adults on the leaves of plants that are vulnerable to aphid damage;

[0035] 2) Collection of egg masses: the Heterochromia adults collected in step 1) are transferred to an egg-laying cage provided with an egg-laying substrate, and 80-120 females and 80-120 males are placed in each egg-laying cage. worm, put fresh aphids regularly and quantitatively every two days in this egg-laying cage, and the feeding unit of every 200 ladybug adults is fed with 4-6g of aphids until the egg laying of the heterochromia is finished. During the oviposition period of insects, regularly collect and replace the oviposition substrate every day. In this application, the aphids fed are all aphids;

[0036] 3) Acquisition of egg card: use computer software to identify and automatically obtain the q...

Embodiment 2

[0049] Using the effects of green peach aphid (Myzus persicae), broad bean aphid (Aphis fabae) and pea aphid (Megourajaponica) on the growth and development of Heterochromia adults, the above three fresh aphids were regularly and quantitatively placed in the egg-laying cage every day. , until the spawning of the heterochromia ladybug ends, in the spawning period of the heterochromia ladybug, regularly collect and replace the spawning substrate every day; every kind of fresh aphid handles and raises 5 groups of ladybugs (20 heads of each group of ladybugs), every day Observe the growth and development indicators and nutritional indicators of the Heterochromatia that feed on different species of aphids. After statistics, the specific indicators are shown in the following table:

[0050]

[0051] Wherein: adult egg-laying rate=(total number of eggs collected / days of eggs collected) / number of adults×100; relative growth rate (RGR)=body weight at the end of the experiment-weight ...

Embodiment 3

[0061] On the basis of Example 1, wherein said step 1) also includes observing the collected ladybugs for more than 2 weeks, continuous screening, removing parasitic wasps in the egg stage, larval stage or adult stage of the parasitic ladybug, and some Entomopathogenic bacteria and fungi are screened to leave at least 1,000 healthy individual adults.

[0062] Since the Heterochromia has many natural enemies in the wild, including several parasitic wasps in the eggs, larvae or adult stages of the parasitic ladybug, as well as some entomopathogenic bacteria and fungi, after collecting the adults of the Heterochromia Conduct isolation and observation for at least two weeks; at the same time, because the heterochromia is sexual reproduction, inbreeding in the population will easily cause the vigor of the offspring to deteriorate, which is not conducive to the continuous feeding of the ladybug. Therefore, a certain amount of adult heterochromia must be guaranteed when the production...

Abstract

The invention discloses a complete method for raising heterochromia, which comprises the following steps: 1) seed selection; 2) collection of egg masses; 3) acquisition of egg cards; 4) rearing of larvae: the preparation in step 3) The heterochromia egg cards are placed in the breeding container for incubation, and the feeding container is divided into multiple layers by spacers, and a certain amount of scraps of paper, egg cards and rice moths are laid between the upper and lower adjacent spacers. Eggs, and the middle position of each spacer is also provided with an inverted plastic cover, the plastic cover is provided with cotton pads filled with honey water, the hatching conditions are 16:8D at the photoperiod and the temperature is 25°C After raising for 10-12 days, when the hatched ladybugs develop to the 3rd instar, the rearing container is moved into the cold storage at 4-6°C for future use. The complete method for raising the heterochromia provided by the present invention has the characteristics of low breeding cost, high breeding efficiency, stable breeding quality, controllable and traceable whole process.

Description

technical field [0001] The invention belongs to the technical field of natural enemy insect breeding, and in particular relates to a complete method for raising heterochromia. Background technique [0002] Biological control is one of the main technologies for the green prevention and control of agricultural and forestry pests, and natural enemy insects are the basis of biological control, so the importance of natural enemy insects is self-evident, and large-scale reproduction of natural enemy insects is the core technology of biological control. Heterochromia is one of the main predatory natural enemies of crop pest aphids, which belongs to Coleoptera insects, it is one of the main natural enemy insects in the field, its adults and larvae can prey on aphids, scale insects, mealybugs, thrips and Lepidoptera eggs and young larvae. Therefore, when the number of heterochromia reaches a certain amount, the number of field aphids and some small pests can be well controlled, and ...
