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 feeding method for the white-striped ladybug. The method is to use pumpkin powdery mildew as the live feed for the larvae and seedlings of the white-striped ladybug, and then use artificial feed as the main food for the adults. Pumpkin powdery mildew bacteria come from pumpkin leaves infected with powdery mildew; artificial feed is configured according to the following mass percentages: glucose 20%, fructose 20%, soybean powder 5%, silkworm chrysalis powder 15%, feed grade vitamin 0.3%, sterile water 39.7% %, the ingredients are cheap and easy to get and rich in nutrition. By adopting the above-mentioned method to raise the white striped ladybugs, the rate of obtaining adults is high, and the female worms have a long oviposition period and a large amount of oviposition. Using the obtained white sclerotia ladybug to prevent and control plant powdery mildew has ideal effect and is economical and environment-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...
