Problems solved by technology

However, after research on various artificial feeds, it was found that due to nutritional deficiencies and other reasons, problems such as low food intake, unhealthy individual development, long pre-oviposition period, no oviposition or low oviposition occurred, and it was necessary to add feeding stimulation factors. and gonadotropins
And the physical properties of artificial feed will also affect feeding. For example, the feed based on pig liver-sucrose is fluid, which is not easy for ladybugs to feed on and easy to agglomerate and mold

Embodiment Construction

[0013] The present invention is further described below.

[0014] The method for multiplying the heterochromia in large quantities by using a formula of alternate food of the present invention, the formula of the alternate food is that the eggs of the mediterranean leaf spot borer cooperate with pig liver pulp.

[0015] There are 3 processing modes for the Mediterranean mealybug borer ovum of the present invention:

[0016] 1. Fresh eggs (store directly in a sealed box and store in a refrigerator at 4°C, and use up within 3 days);

[0017] 2. Eggs treated with ultraviolet rays (put the plastic plate in the refrigerator for 2 minutes, take it out and place it in the air, sprinkle the eggs of Mediterranean mealylosia moth on the surface after the surface is moistened, spread it evenly on the plastic plate in a single layer, and place it on the plastic plate. 30-40 minutes on a 30cm countertop under a 20W UV lamp, then collect the eggs, store them in a sealed box in a refrigerat...

Abstract

The invention relates to a method for mass propagation of harmonia axyridis by utilizing a formula of an alternative food and application and discloses a method for mass propagation of harmonia axyridis by utilizing anagasta kuehniella eggs and pork liver pulp as basal feed. At 18-32 DEG C, harmonia axyridis can grow normally, body weights are increased, spawning periods and service lives are prolonged, and the egg laying amount is improved and is 5004 at most and far exceeds the egg laying amount obtained by using conventional artificial feed or other natural prey. According to the method, foods are easy to store and high in utilization rate, the foods are easily used simultaneously with other artificial feed or natural prey, and the production cost is further reduced. The method is simple and convenient to sue and high in harvest rate.

Description

technical field [0001] The present invention relates to the method and application of a large number of propagation of heterochromia ladybugs with a formula of alternate food. Background technique [0002] As an excellent pest hunter, Heterochromia has the advantages of a wide range of predation, a large number of prey, a long lifespan, and strong adaptability. It has broad prospects in the biological control market of pests. The feeding and reproduction of natural enemies is the key to biological control. Scientists have also conducted a lot of research on the mass reproduction of Heterochromia and artificial feed. However, after research on various artificial feeds, it was found that due to nutritional deficiencies and other reasons, problems such as low food intake, unhealthy individual development, long pre-oviposition period, no oviposition or low oviposition occurred, and it was necessary to add feeding stimulation factors. and gonadotropins. And the physical propert...
