Problems solved by technology

At present, the feeding of ladybugs is still dependent on living aphids, and the growth and development of ladybugs and aphids cannot be quantitatively controlled during the reproduction process. The reproductive efficiency and quality are unstable, which limits its mass reproduction and application. The key factor lies in the development of Efficient artificial feed suitable for factory breeding and its technical method

Embodiment 1

[0049] Example 1. Preparation method of artificial feed

[0050] The test site is located in Laboratory 512, Institute of Environment and Plant Protection, Chinese Academy of Tropical Agricultural Sciences.

[0051] The feed in this embodiment is divided into the following 7 types according to the composition and form of the raw materials:

[0052] Feed A: pellets. The feed ingredients consist of 5 grams of yeast powder, 5 grams of sucrose, 20 grams of pig liver, 0.01 grams of vitamins, 0.05 grams of cholesterol, and 8 grams of honey. The preparation steps are: 1. First cut the fresh pig liver into fine granules, and store it in the refrigerator at 4°C for later use; 2. Then weigh the yeast powder, sucrose, vitamins, cholesterol, and honey according to the above weight ratio. , And put them into a pulverizer to pulverize into powder; 3. Take out the mixed powder in 2 and add yeast powder, honey and liver of the corresponding mass ratio to it, mix well, put it into the bottle and se...

Embodiment 2、 6

[0062] Example 2. Male and female lifespan of adult ladybird beetle under different artificial diets

[0063] The test site is located in Laboratory 512, Institute of Environment and Plant Protection, Chinese Academy of Tropical Agricultural Sciences.

[0064] The source of the ladybird beetle tested: The source was collected from the carob field around Haikou City, Hainan Province, and was raised by cowpea aphid to establish a population.

[0065] Source of test aphids: collected from cowpea aphids around Haikou City, fed and reproduced with broad bean seedlings planted in an artificial climate chamber.

[0066] The newly emerged adult six-spot ladybirds were fed with the above artificial diet (A-D), and their lifespan was observed, and the aphid feeding was used as a control group. Three groups of parallel experiments (3 repetitions) were done for each food, and each group of experiments contained 20-30 treatments. Each treatment was fed with a pair of female and male worms in a pla...

Embodiment 4

[0078] Example 4. The effect of eggs and pollen in the feed C component on the lifespan and fecundity of ladybirds

[0079] The test site, test insect source and test method are the same as those in Examples 2 and 3. This example mainly observes the effect of whether the feed C contains eggs, or (and) pollen on the lifespan and fecundity (oviposition) of female and male ladybirds. During the specific test, the survival status and oviposition status of the female and male insects of the feed C (containing eggs and pollen), E (removing eggs), F (removing pollen), and G (removing eggs and pollen) were recorded every day.

[0080] The results are shown in Table 4: When the fodder contains both eggs and pollen (feed C), the female and male worms have the longest lifespan and the largest number of eggs when fed to the ladybird. In contrast, when the eggs are removed (feed E) or the eggs are removed (feed F), the lifespan and egg production of the test insects are significantly reduced; ...

Abstract

The invention relates to an artificial feed for breeding adult worms of ladybug sexmaculates. The artificial feed is composed of yeast powder, sucrose, pig liver, vitamins, cholesterol, honey, olive oil, oatmeal, eggs and pollen. The product can be prepared in the form of granules, powder and agar. Among them, the feed in a powdered state has the best effect, and the mass ratio is: 50-60:50-60:200:0.1-0.3:0.5-0.7:80-100:3-4 :50-70:50-70:30-50. The feed formula can satisfy the normal life activities of the adult worms of the ladybug sexmaculates, and the biological characteristics and the predation effect are not different compared with the natural prey aphid of the ladybug. The raw materials of the feed of the invention are easy to obtain, the product is convenient to prepare, easy to operate, low in cost, and is beneficial to factory production, and provides a technical and material basis for large-scale reproduction and application of ladybugs.

Description

Technical field [0001] The invention belongs to the field of agricultural feed, and specifically relates to an artificial feed for raising adult ladybirds of the six-spot ladybird and a preparation method thereof. Background technique [0002] Menochilus sexmaculates belong to the Coccinellidae family of Coleoptera, which is a very important natural enemy ladybird, which is widely distributed in many countries and regions in the world. [0003] The six-spot ladybird has the advantages of long life span, large predator capacity and high fecundity. It has good biological control efficiency against aphids, whiteflies, red spiders, thrips and other important agricultural pests. [0004] Feeding natural enemy insects with artificial feed can break host restrictions, reduce feeding costs, effectively control insect growth and development, and facilitate the reproduction and commercial application of natural enemy insects. At present, the feeding of ladybirds still depends on live aphids, ...
