The invention relates to an artificial mass propagation method of harmonia axyridis. Two facilities of a seedling raising greenhouse and an insectary are adopted, broad beans are used as host plants for propagating pea aphids which are used as aphids for feeding the harmonia axyridis, and the harmonia axyridis which is used for agricultural control over the aphids can be manually propagated in a large quantity through specific technical measures of broad bean plant breeding, pea aphid inoculation and propagation, artificial breeding of the harmonia axyridis and the like. Healthy broad bean sprouts are bred with broad bean seeds, the pea aphids are inoculated with the broad bean sprouts and propagated, then the pea aphids are collected to feed larvas and adults of the harmonia axyridis, and a large quantity of the larvas and the adults of the harmonia axyridis are propagated to be released in agricultural production areas to control the aphids of all kinds, so that the biological control over the aphids is realized, and the pollution and safety problems caused by chemical control is avoided or reduced.

The invention provides a method for artificially feeding ladybirds and / or lacewings. The method comprises the following steps of: (1) incubating lepidoptera insect larvae after lepidoptera insect adults lay eggs, and feeding the lepidoptera insect larvae with feed; (2) feeding ladybird larvae and / or lacewing larvae by using the lepidoptera insect larvae as feed to obtain ladybird adults and / or lacewing adults, wherein the lacewings are selected from one of chrysopa septempunctata and chrysoperla nipponensis; and (3) feeding the ladybird adults and / or chrysopa septempunctata adults by using the lepidoptera insect larvae as the feed, and feeding chrysoperla nipponensis adults by using honey and beer dry yeast powder. Compared with the prior art, the method for feeding the ladybirds and the lacewings in a large scale by using the lepidoptera insect larvae as the feed replaces the conventional method for feeding the ladybirds and the lacewings which are natural enemies of aphids by using the aphids cultured by plants, and the method saves more time and labor, is simpler and more convenient and is easier to operate.
