Embodiment 1

[0052] The large-scale propagation of embodiment 1 pea aphid

[0053] 1.1 Host plant cultivation

[0054] After screening, the broad bean variety that is the natural king was selected as the host plant for the expansion and propagation of the pea aphid. Excellent host plants for aphids.

[0055] The specific steps of using broad bean seedlings to raise aphids on a large scale are as follows: under the conditions of 25±1°C indoors and a photoperiod of 16L:8D (16 hours of light during the day and 8 hours of darkness at night), feed the aphids to 24-hole seedling pots (30×20×10cm) Put the sterilized vermiculite inside, the thickness of the vermiculite is about 2.5cm, flatten the vermiculite to make the filling slightly tight, screen a large and plump broad bean seed and sprinkle it evenly on the vermiculite, each pot is divided according to every 600cm 2 The ratio of sowing 200-220 grains of broad beans is carried out to raise seedlings, and evenly spread a layer of vermiculite...

Embodiment 2

[0060] The scale propagation of embodiment 2 Lacewing

[0061] 2.1 Management and hatching of Lacewing eggs

[0062] Under the indoor conditions of 26±1°C and 16L:8D, the adults were placed in pitcher cages (60×60×60cm) and reared with P. pea for successive generations to establish a stable population. From the spawning day of newly emerged adults, new eggs were regularly collected every day, and the eggs were placed in a rearing box (30 cm) with folded filter paper strips (length 30 cm × width 1.5 cm, to prevent lacewing larvae from killing each other) at the bottom. ×20cm×10cm). like figure 1 As shown, the breeding box includes a box body 1 and a box cover 2; the top of the box body 1 is open, and a folded filter paper strip 3 is arranged inside the box body 1; the box cover 2 is covered on the top of the box body 1; the middle of the box body 2 is cut open A rectangular through hole (20cm×12cm) is covered with a gauze 4 made of 60-mesh nylon material, and the gauze 4 has...

Embodiment 3

[0069] The packaging and storage of embodiment 3 lacewing products

[0070] According to the production demand, under the premise of ensuring the regular multiplication of Lacewings, the eggs, larvae, cocoons and adults of Lacewings produced can be used for a variety of aphids, mites, thrips, scale insects and Lepidoptera pests in the field etc. prevention and treatment. In order to facilitate the transportation and application of the product, each insect form of Lacewing should be packaged before use. The packaging method is as follows.

[0071] 3.1 Packaging of lacewing eggs

[0072] The lacewing ovum is cut from the ovum stalk, collected in a glass petri dish (9 cm in diameter), and then with a soft hair brush, the ovum is gently swept to a removable area pasted with double-sided adhesive tape (long 4 cm, wide 3 cm). Fold the two sides of a rectangular three-dimensional paper card (13cm in length and 4cm in width) into a ridge shape in half, and leave a circular hole with...

Abstract

The invention relates to chrysopa formosa packaging and storing methods. According to the growth stage of chrysopa formosa, the proper packaging method is selected, three-dimensional paper card type packaging is adopted for chrysopa formosa eggs, bottle type packaging is adopted for chrysopa formosa larvae, three-dimensional paper card or bottle type packaging is adopted for chrysopa formosa cocoons, and cassette packaging is adopted for chrysopa formosa adults. The storing method comprises short term refrigeration storing and / or long term diapause storing. Accordingly, simple, rapid and efficient packaging and effective storing of all insect state products of the chrysopa formosa are achieved, the product shelf life is significantly prolonged, the product storage quantity is increased, the packaging, transportation and storing cost is lowered, standardized perennial large-scale production of the chrysopa formosa is easily achieved, the methods can be used for controlling multiple agriculture and forestry pests such as aphides, whitefly, scale insects, pest mites, lepidoptera eggs and young larvae, and biological control needs of facility vegetables, fields, orchards, flowers and the like are met.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to a method for packaging and storing lacewing products. Background technique [0002] Aphids are major pests in the world's agricultural and forestry production. They are widely distributed in the world and are widely distributed in my country. Among them, Liaoning, Hebei, Gansu, Xinjiang, Beijing, Yunnan and Taiwan are relatively densely distributed. Aphids have a wide range of hosts, a large number of occurrences, rapid reproduction, and serious generation overlap. They can harm plants through feeding, honeydew pollution, and virus transmission, causing plant growth retardation, wilting, and inducing various viral diseases and black mold. Diseases, etc., cause damage to plant organs and loss of nutrients. In severe cases, it can lead to plant death, and cause the occurrence and prevalence of plant diseases, causing great economic losse...
