Artificial feed for asparagus caterpillar, preparation of artificial feed and feeding method

The invention relates to an artificial feed for asparagus caterpillar, preparation of the artificial feed and a feeding method, and belongs to the field of insect feeds. The artificial feed for asparagus caterpillar comprises the following components: wheat bran, chenopodium album powder, corn flour, ripe soybean powder, yeast powder, agar powder, distilled water, cholesterol, soybean edible oil, ascorbic acid, methyl parahydroxybenzoats and sorbic acid. Raw materials used for the feed are easy to obtain; the preparation technology is simple; the cost is relatively low; the guarantee period is relatively long (6 months); chenopodium album can reduce the viscosity of the feed, enhance the survival rate and percentage of pupation of larvae, can reduce the abnormal pupa rate, and can provide various vitamins required for the development of larva, so that the fed asparagus caterpillar has the average pupal weight of 111.8mg, has the average moth weight of 100.4mg, has the larva survival rate of 91%, and has the eclosion rate of 98%; the pupas have strong vitality, and can be stored in a refrigerator with the temperature of 5 DEG C for 7 days; the feed is relatively good in feeding effect and achieves the aim of long-term large-scale continuous rearing.

Disclosed are an artificial rearing method of hepialidae and a feed composition of hepialidae larvae. The artificial rearing method of hepialidae meets the following conditions of 1, artificial feeding condition of the larvae, wherein the temperature is 8-23 DEG C, the relative humidity is 75-85%, aseptic water is adopted for humidification, and an overall dark environment is provided; 2, the storage conditions of pupae, wherein female and male pupae which pupate at the same day are placed at different temperatures; 3, mating and spawning conditions of imagoes, wherein female and male imagoesafter eclosion are placed in an imago cage which is provided with a gauze screen and internally contains fresh host plant indigowoad leaves in a bottled mode, the imagoes can stay in a suspended mode,move, courtship, mate and spawn in the cage, the temperature is 23-25 DEG C, the relative humidity is 65-80%, and the photoperiod is (11-13)L:(13-11)D; 4, the artificial feed composition of the hepialidae larvae and a preparation method thereof; 5, disinfection treatment of the rearing environment. By means of the artificial rearing method of hepialidae and the feed composition of the hepialidaelarvae, the survival rate of the larvae can be significantly increased, the eclosion rate of the pupae can be increased, and the success rate of imago mating is increased.

Breeding method for preventing aphidius gifuensis species from degrading

The invention discloses a breeding method for preventing aphidius gifuensis species from degrading. The breeding method consists the steps: bee species collection: collecting mummified aphids formed by artificial breeding of aphidius gifuensis and mummified aphids formed by field aphidius gifuensis, and storing the aphidius gifuensis in test tubes; bee species cultivation: placing the test tubes in an arterial climate box for cultivation, purifying the aphidius gifuensis after the mummified aphids in the test tubes are hatched into aphidius gifuensis; aphidius gifuensis mating: mating the artificially bred aphidius gifuensis and the field aphidius gifuensis; breeding: selecting myzus persicae, namely the host of aphidius gifuensis, and making the mated aphidius gifuensis to naturally breed with myzus persicae; when myzus persicae start to form mummified aphids, screening and collecting the mummified aphids and storing the mummified aphids in a storage bottle to obtain the bred mummified aphids. The breeding method mates and cultivates the artificially bred aphidius gifuensis and the field aphidius gifuensis, improves the eclosion rate and the spawning rate of aphidius gifuensis, meanwhile improves the activity of aphidius gifuensis and the quality of the aphidius gifuensis species, and prevents the aphidius gifuensis species from degrading.

Enhanced cultivation device for adult hermetia illucens and cultivation method of adult hermetia illucens

PendingCN112913787AMultiple living spacesFollow biometricsAnimal husbandryHermetiaMating
The invention discloses an enhanced cultivation device for adult hermetia illucens and a cultivation method of the adult hermetia illucens. The device comprises a darkroom and a bright room which are in communication with each other; an outer cover of the darkroom is made of a breathable and lightproof material, the side surface of the darkroom is provided with a hermetia illucens pupa inlet, an adult fly-out opening connected to the bright room and an observation window, and a platform on the bottom surface of the darkroom is provided with a pupal larva container; an outer cover of the bright room is made of a breathable and light-transmitting material, and an adult fly-in opening, an egg receiving window and a halogen lamp are arranged on the side surface of the outer cover of the bright room; and a box for containing an egg inducing object is arranged in the bright room and is used for receiving eggs. According to the enhanced cultivation device and the ultivation method, pupation, eclosion and adult mating of the hermetia illucens are controlled in the darkroom and the bright room respectively, the biological characteristics of the hermetia illucens are followed, the eclosion rate of the hermetia illucens pupae is remarkably increased, the mating space is not limited by a containing container for pupal larvae, more living spaces and social places are provided for the adult larvae, and the mating rate and the egg laying amount are increased. Adults with different sources and generations in different darkrooms are hybridized through the movable bright room, excessive inbreeding is avoided, and offspring activity is kept.

Multi-functional cup integrating rice field lamina color comparison and natural enemy releasing

The invention discloses a multi-functional cup integrating rice field lamina color comparison and natural enemy releasing. The multi-functional cup comprises a color comparison cup body with the lower end open, a food groove and a connecting rod. A connecting hole and a ventilation hole are formed in the upper end face of the color comparison cup body, and a trichogramma card is attached to the inner wall of the color comparison cup body. The connecting rod penetrates through the connecting hole, the lower end of the connecting rod is connected with the food groove, and the food groove is located in the color comparison cup body. Due to the fact that colors of cup bodies different in green degree are compared with colors of rice field laminas, the fertilizer condition of a rice field can be timely judged, a farmer is instructed to appropriately perform topdressing and fertilizer controlling at appropriate time in the production process of grain, so that blind fertilizer application is avoided in the process of planting rice; meanwhile, the cup can serve as an emergence place of trichogramma before the trichogramma enters parasitic stem borer eggs of the rice field and provides a good emergence environment for the trichogramma, and the parasitic capacity, in the rice field, of the trichogramma is improved, so that the efficiency of pest control is promoted.
