Embodiment 1

[0033] like figure 1 and image 3 As shown, a complete set of methods for efficiently raising Heterochromia comprises the following 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 automati...

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 efficiently feeding harmonia axyridis. The complete method comprises the following steps that (1) seeds are selected; (2) egg masses are collected; (3) egg cards are obtained; and (4) larvas are fed, wherein the harmonia axyridis egg cards prepared in the step (3) are placed in a feeding container to be incubated, the feeding container is divided intomultiple layers through spacers, a quantitative number of shredded paper scraps, egg cards and rice moth eggs are laid between every two vertically-adjacent spacers, an inverted plastic cover is further arranged at the middle position of each spacer, makeup cotton fully absorbing honey water is arranged in the plastic covers, feeding is carried out for 10-12 days under the incubation conditions that the photoperiod is 16: 8D and the temperature is 25 DEG C, and when the incubated harmonia axyridis grows to be 3 years old, the feeding container is moved into a refrigeration house to be stored at the temperature of 4-6 DEG C for standby application. The complete method for feeding the harmonia axyridis has the advantages that the breeding cost is low, the breeding efficiency is high, the breeding quality is stable, and the whole process is controllable and traceable.

Description

technical field [0001] The invention belongs to the technical field of breeding natural enemy insects, and in particular relates to a complete set of methods for efficiently raising the heterochromia ladybug. 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 p...
