Problems solved by technology

[0003] The seven-spot ladybug is an insect of the order Coleoptera and the ladybug family. It is an important natural enemy of a variety of aphids in crops. However, there are still few reports on its artificial indoor breeding. The reason is that the biggest problem is the artificial breeding of ladybugs. The feed problem needs to be solved. Ladybugs use aphids as their main feed, but relying on wild collection of aphids is not only time-consuming and labor-intensive, but it will be difficult to obtain a large number of aphids if they encounter a shortage of aphid sources and seasonal restrictions, which will seriously affect the growth of artificially raised ladybugs. Breeding will also lead to the failure of normal biological control work in the next year

Embodiment 1

[0021] 1) Crush the camellia seed meal and pass it through a 40-mesh sieve, add petroleum ether for reflux extraction at 60°C for 2 hours to remove oil, add 70% ethanol for ultrasonic extraction for 40 minutes, filter, add activated carbon to the filtrate for decolorization, and concentrate to obtain Tea saponin;

[0022] 2) After filtering the waste water in the pre-processing process of bamboo fiber, mix it with ethanol with a mass fraction of 80% in a volume ratio of 1:2, and repeat the extraction for 3 times at an extraction temperature of 70°C for 2 hours each time, and the extract is filtered by suction , and the filtrate was concentrated to obtain bamboo flavonoids;

[0023] 3) Wash 6 kg of fresh pork liver, cut it into small pieces, stir it with 8 kg of fish roe, and process it into a homogenate;

[0024] 4) Dilute honey with water to form a sugar solution; add 5 kg of the homogenate obtained in step 1) and egg yolk powder into the sugar solution and mix evenly, then ...

Abstract

The invention discloses a coccinella septempunctata feed as well as a preparation method and application thereof. 10 to 12 parts of sweet water, 8 to 10 parts of fish eggs, 6 to 8 parts of pork liver, 5 to 8 parts of yolk powder, 5 to 6 parts of bamboo flavone, 3 to 4 parts of teasaponin, 4 to 5 parts of vitamin complex, and 4 to 5 parts of olive oil are used as formula raw materials, and the formula raw materials are subjected to homogenate, dipping and mixing, so as to obtain the coccinella septempunctata feed. The coccinella septempunctata feed can replace aphid to be used as feed for coccinella septempunctata artificial feeding, fills the gap of the feed for coccinella septempunctata artificial feeding, can also improve the adaptability and the disease resistance of coccinella septempunctata and improve the biological control capacity, and can also be used as feed additive during the ecdysis of the coccinella septempunctata larva, and is mixed with aphid larva to feed coccinella septempunctata, so as to replenish the nutrition consumed during the ecdysis and promote the larva to grow fast.

Description

technical field [0001] The invention belongs to the field of ladybug breeding, and in particular relates to a seven-star ladybug feed and a preparation method and application thereof. Background technique [0002] With the rapid development of the agricultural industry, the "3R" phenomenon caused by the use of a large amount of chemical pesticides, and people's demand for green and organic food, the biological control of pests has received more and more attention, and the corresponding biological control technology has also been developed rapidly. At present, western developed countries have taken the development of biological control technology as one of the important strategic decisions to alleviate the world environmental crisis. [0003] The seven-spot ladybug is an insect of the order Coleoptera and the ladybug family. It is an important natural enemy of a variety of aphids in crops. However, there are still few reports on its artificial indoor breeding. The reason is t...
