Problems solved by technology

[0004] Since pea aphids are pests, artificial breeding of pests requires artificial isolation; precipitation will have a strong scrubbing effect on aphids, and artificial breeding of pea aphids must have rainproof facilities; the most important thing is that continuous planting of peas leads to soil acidification, which in turn produces Rhizome diseases of broad beans cause wilting, lodging, root rot and death of broad beans, and reduce the propagation speed of pea aphids

Embodiment 1

[0062] Embodiment 1: the method for artificially multiplying pea aphids in large quantities of the present invention comprises the following steps:

[0063] a. Seed treatment: soak the broad bean seeds in water for 24 hours, and air-dry them for 12 hours to prepare for sowing;

[0064] b. Filling the substrate and sowing: Fill the seedling raising floating tray with moist tobacco seedling raising substrate that is kneaded into a mass and then loosened until the substrate plane is consistent with the floating tray plane; select broad bean granules with full grains, and insert one seed into each seedling raising hole ;

[0065] c. Floating dish enters water: in black water dish, fill water 50cm deep, add the tobacco compound fertilizer of 20g active ingredient N:P:K=10%:10%:20% in water dish; Put the pan into a black water pan with sufficient water and fertilizer;

[0066] d. Emergence inoculation: 3 days after sowing, the broad beans basically emerged, and a small number of u...

Embodiment 2

[0071] Example 2: In May, when field aphids begin to occur, predatory natural enemies need to be multiplied in large quantities, which belongs to the expansion breeding mode. The natural enemy insects reproduce in large numbers, and the number increases sharply. Each time the seedlings are raised, a floating tray is added until the seedling space is full, and then enters the stable multiplication mode. In the expansion breeding mode, the food demand continued to increase, and 6 batches of seedlings were maintained, with a 30-day cycle. Each batch of seedlings provides food for 5 days, that is, the broad bean seedlings are divided into 5 parts, and one part is cut every day (only the stem tips covered with pea aphids are cut), and put into the natural enemy insect insect breeding box. If pea aphids are not enough to use, natural enemy insects will ensure the full utilization of limited food through natural selection by survival of the fittest.

Embodiment 3

[0072] Example 3: In August, a large number of aphids occurred in the field, and the natural enemy insects produced at full capacity, which belonged to the stable multiplication mode. During this period, the seedling space was operating at full capacity, the amount of seedlings remained basically unchanged, and the production of pea aphids also remained basically unchanged. Still maintain 6 batches of seedling cultivation, a cycle of 30 days, and each batch of seedlings provides food for 5 days. When the pea aphid cannot provide enough food, the excess natural enemy insects are released in the field to ensure the expansion of the production of the remaining insects.

Abstract

The invention belongs to the field of green pest insect prevention and control, relates to a method for artificially breading great amounts of pea aphids. The method includes the following steps of a, processing seeds, b, filling substrate and sowing, c, inputting a floating disc into water, d, seedling vaccination, e, aphid stock, f, seedling shearing and aphid feeding, g, later-period processing and h circulating. The method for artificially breading the pea aphids relates to the artificial expanding breeding method of living body food insects, and the method is suitable for artificial feeding of natural enemy insects.

Description

technical field [0001] The invention relates to a method for artificially multiplying pea aphids in large quantities. Background technique [0002] The biological control of aphid insects mainly relies on the field release of natural enemy insects (such as Heterochromia, Seven-spotted Ladybug, Moleopteria, Polydactylyx, Cyrhidrium cerevisiae, and large lacewings, etc.), while the artificial release of natural enemy insects Feeding is inseparable from the massive expansion of live feed. Pea aphid is currently a theme feed for natural enemy insects because of its large size and strong fecundity. [0003] In our laboratory, a large number of Heterochromia was released in the field to control Aphids persicae, mainly through the large-scale multiplication of Pea Aphids to provide the live nutrition required for the growth of Heterochromia larvae and adult oviposition. Broad bean is currently the main host plant for artificial cultivation of pea aphid because of its large biomas...
