Problems solved by technology

Sighinolfi et al. (2008) fed an artificial diet based on pig liver to the larvae and adults of Heterochromia respectively, and found that eating the artificial diet at the larval stage would lead to a prolonged developmental period, a decrease in eclosion rate, and weight loss in adults. Eating the artificial diet will greatly affect the fecundity of adults
[0006] There are also researchers who formulate a feed mixed with insect-derived components and non-insect-derived components to feed the adults of Heterochromatia, but the fecundity of the raised lady beetles is still greatly affected

Embodiment Construction

[0024] The principles and features of the present invention are described below in conjunction with examples, which are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0025] 1. Preparation of artificial feed

[0026] Use the following methods to prepare artificial feed:

[0027] 1) Take fresh pig liver, wash it, blot dry the surface water, grind it in a grinder for 2-3min, filter out the tissue that has not been fully ground, and obtain a homogenate of pig liver;

[0028] 2) Add 3 parts by weight of fly maggot powder, 4 parts by weight of yeast extract, 4 parts by weight of sucrose and 10 parts by weight of honey in the homogenate of pig liver of 3 parts by weight, and stir evenly to obtain a uniform mixture;

[0029] 3) Add S-methoprene (see Table 1 for the amount added) to the mixture and stir evenly to obtain the artificial feed. The artificial diet was stored at 4°C for long-term storage.

Abstract

The invention relates to an artificial fodder for imaginal harmonia axyridis. The artificial fodder is characterized by using pork liver homogenate, fly maggot powder, yeast extract, cane sugar, and honey as main components, and further containing 0.1-100mg / Kg of juvenoid hormone analogues. The juvenoid hormone analogues is added to the artificial fodder for harmonia axyridis, thereby stimulating the ovarian development and feeding of the harmonia axyridis, and the problem that the imaginal harmonia axyridis cannot spawn after being fed with ordinary artificial fodder is solved. Compared with the prior art, the fodder disclosed by the invention is simple in ingredient, easy to prepare, low in cost, and capable of guaranteeing the fertility of the imaginal harmonia axyridis, and the hatchability and the survival rate of the filial ladybird and the imago yield are high.

Description

technical field [0001] The invention relates to the field of insect feeding, more particularly, to a feed for the heterochromia ladybug and a preparation method thereof. Background technique [0002] The heterochromatic ladybug Harmonia axyridis (Pallas), belongs to Coleoptera (Coleoptera), Coccinellidae (Coccinellidae), it can effectively prey on a variety of aphids, Lepidoptera pest larvae, etc., is an important predator in my country and Asia Sexual natural enemy insects (Wang Xiaoyi et al., 2002). Heterochromia has a large predation capacity, wide distribution, and strong fecundity, and is often used for ecological pest control. Finding effective artificial feeds to efficiently raise and breed Heterochromia artificially indoors and reduce the reproduction process of natural feed aphids is an important technical link for the artificial propagation of Heterochromia in large numbers and large-scale field development and utilization. [0003] Many scholars have done a lot o...
