Embodiment 1

[0025] With squash powdery mildew bacteria as the live feed of the larvae and seed worms of the white striped ladybug, with the artificial feed as the main food of the adults, the feeding method comprises the following steps:

[0026] (1) Preparation before feeding

[0027] All petri dishes, rearing boxes, spawning boxes and other high-temperature-resistant appliances need to be sterilized by a steam sterilizer before use. The sterilization conditions are: temperature 120°C, time 15-30min, and appliances that cannot be It needs to be disinfected with 75% alcohol for more than 30s before use.

[0028] Soak some pumpkin seeds for 4 hours and configure 10% bee water.

[0029] Make egg collection nets as designed. The egg collection net is made of white gauze (PP material) the size of A4 paper, with a hole diameter of about 1.2-1.4 mm. It is folded from the middle so that the angle after normal unfolding is 30°-90°. Soak in 10% honey water for 30s and let it dry naturally.

Abstract

The invention discloses a breeding method of halyzia hauseri. The breeding method comprises the following steps that pumpkin powdery mildew is used as living feed for larvae and breeding insects of the halyzia hauseri, and artificial feed is used as main food for adults to feed the larvae and the breeding insects of the halyzia hauseri. The pumpkin powdery mildew comes from pumpkin leaves infected with powdery mildew. The artificial feed is prepared from the following components in percentage by mass: 20% of glucose, 20% of fructose, 5% of soybean meal, 15% of silkworm chrysalis meal, 0.3% of feed-grade vitamins and 39.7% of sterile water, and the ingredients are cheap, easy to obtain and rich in nutrition. By adopting the method to breed the halyzia hauseri, the adult yield is high, the egg laying period of the female ladybird is long, and the egg laying amount is large. The obtained halyzia hauseri is used for preventing and treating plant powdery mildew, the effect is ideal, and the breeding method is economical and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of ladybug breeding, in particular to a method for raising ladybugs with white stripes. Background technique [0002] Powdery mildew fungus, belonging to Ascomycota subphylum Sclerotinia, Erysidiomycetes, Erysiphaceae, is a kind of pathogenic fungus that obligately parasitizes the surface of plants and produces white powdery disease. When powdery mildew bacteria harm plants, they use their haustoria to penetrate into the host cells to absorb nutrients and expand under the epidermis. The affected parts of the plants gradually turn green and turn yellow, and even the whole leaf dies. Generally speaking, powdery mildew bacteria have high host specificity, and can be divided into powdery mildew fungi that specifically infect economic forest plants, such as prickly pear powdery mildew, apple powdery mildew, wolfberry powdery mildew, etc.; cucumber powdery mildew that specifically infects crops Bacteria, wheat po...
