Problems solved by technology

[0004] The field release of Heterochromia mainly relies on a large number of artificial indoor breeding and hauling to the field for release, which consumes a lot of human resources and transportation costs
At the same time, the heterochromia obtained from indoor breeding lacks good adaptability to the complex and changeable external environment in the field, resulting in a large number of dead

Embodiment 1

[0038] The method for a large number of multicolored ladybugs in the field of the present invention is characterized in that it comprises the following steps:

[0039] a. Prepare pea aphids: plant broad beans in the field to form a small rectangle of 3m*3m. When the broad beans grow to 25cm, inoculate pea aphids with a density of 5 heads / plant, and cover the small shed for raising insects at the same time;

[0040] b. Raising egg-laying adults: Putting egg-laying adults and pea aphids into the insect cages with 200 broad bean plants per strain, egg-laying adults lay eggs on the broad bean plants, and cutting the broad bean tenders that are full of pea aphids every day. Tips to supplement fresh pea aphids to provide ample food;

[0041] c. Collect egg masses: Before feeding the egg-laying adults every day, check all the young broad bean leaves and live broad bean leaves that were put in the day before. After finding the egg masses, use scissors to cut the leaves with egg masses...

Abstract

The invention relates to a field large-scale propagation method for harmonia axyridis. The method is characterized by comprising the following steps: (a) preparing pea aphids; (b) feeding egg laying adults; (c) collecting egg masses; (d) hatching eggs; (e) managing first-instar larvae; (f) inoculating second-instar larvae to fields; (g) carrying out field management on harmonia axyridis; and (h) carrying out field release of harmonia axyridis. The method has the advantages that harmonia axyridis is raised in the fields, so that the artificial culture cost, field transportation cost and field release cost are reduced, and the adaptability of released harmonia axyridis to field climate is improved.

Description

technical field [0001] The invention belongs to the field of green prevention and control of pests, and in particular relates to a method for mass propagation of ladybug heterochromia in the field. Background technique [0002] As one of the important means of comprehensive management of pests, biological control has the characteristics of high benefit, no pollution, safe for humans and animals, and conducive to environmental protection. With the development of modern agriculture, it has been widely valued. As a special resource, natural enemy insects It is also more and more accepted by people. Developed countries began to develop the natural enemy insect industry in the 1960s. At present, there are about 150 kinds of natural enemies in the world that are commercially produced and sold. certain social and economic benefits. [0003] Heterochromatia belongs to Cooperidae of the order Coleoptera, and is the main predatory natural enemy of a variety of aphids, whiteflies, mi...
