Problems solved by technology

[0003] The artificial breeding of Heterochromia needs a large amount of live food (such as aphid), and the breeding of aphid live food needs to plant a large number of host plants (such as tobacco leaves), but the growth of aphids is dependent on temperature, humidity and light. Strong, difficult breeding of aphids, high cost, large labor input, and high technical difficulty are the main problems restricting the large-scale reproduction of Heterochromatia at this stage

Embodiment 1

[0013] Embodiment 1: the multiplication method of a kind of heterochromia ladybug of the present invention comprises the following steps:

[0014] a. Tobacco seeding: large-scale production of tobacco seedlings in seedling cultivation workshops using seedling cultivation materials;

[0015] b. Aphid inoculation: start to inoculate the aphid when the tobacco seedling grows to the three-leaf one-heart stage;

[0016] c. Ladybug inoculation: 20 days of multiplication of aphids, and when the number of aphids per plant is 200, start to inoculate the newly hatched larvae of ladybugs;

[0017] d. Collection of ladybugs: The growth of ladybug larvae on the tobacco seedlings is carried out simultaneously with the proliferation of aphids. The heterochromia begins to pupate in large quantities after 12 days of growth, enters the peak of pupation in 15 days, and can realize all pupations in 18 days ;

[0018] e. Cryopreservation: the Heterochromia pupae are stored in the refrigerator at...

Abstract

The invention relates to a propagation expanding method for harmonia axyridis. The method includes the following steps: a. sowing of tobacco seedlings; b. inoculation of myzus persicae; c. inoculationof ladybirds; d. collection of the ladybirds; e. freezing preservation; and f. daily management. By utilization of tobacco seedling greenhouse facilities, the method achieves large-scale production of the tobacco seedlings, and enables the breeding cost to be reduced. By the utilization of the tobacco seedling greenhouse facilities, temperature, humidity, lighting conditions and isolation conditions required for the myzus persicae and the ladybirds are satisfied, and the mortality rate of the myzus persicae and the ladybirds is reduced. Through collection and exposure of pupae, convenient collection and storage of the harmonia axyridis can be achieved, and transportation and inventory mortality rate of the ladybirds can be reduced; and through the freezing preservation of the pupae, large-scale storage, and transportation at any time and releasing at any time of the ladybirds can be achieved, and the inventory cost is reduced.

Description

technical field [0001] The invention relates to a multiplication method of the heterochromia ladybug. Background technique [0002] The heterochromatic ladybug Harmonia axyridis (Pallas), belonging to Coleoptera (Coleoptera), Coccinellidae (Coccinellidae), can effectively prey on a variety of aphids, whiteflies, mites and other pests, and is an important predator in my country and Asia. Natural enemy insects. As an excellent pest hunter, Heterochromia has the advantages of a wide range of prey, a large number of prey, a long lifespan, and strong adaptability. It has broad application prospects in the field of biological control of pests. [0003] The artificial breeding of Heterochromia needs a large amount of live food (such as aphid), and the breeding of aphid live food needs to plant a large number of host plants (such as tobacco leaves), but the growth of aphids is dependent on temperature, humidity and light. Stronger, aphid breeding is difficult, the cost is higher, t...
