Embodiment Construction

[0019] The present invention is further illustrated below by means of examples, but the present invention is not limited thereto within the scope of the examples. For the experimental methods that do not specify specific conditions in the following examples, select according to conventional methods and conditions, or according to the product instructions.

[0020] In the following examples, unless otherwise specified, all reagents and materials used are commercially available.

[0021] In the present invention, the host plant is first cultivated with nutrient solution, and then inoculated with leaf-eating pests or juice-sucking pests that harm the host plant, and then inoculated with natural enemy insects of the current leaf-eating pests or juice-sucking pests, so as to breed a natural enemy insect corresponding to the host plant pest method.

[0022] Now take the broad bean seedling as the host plant, the bean aphid as the harmful insect, and the seven-star ladybug as the co...

Abstract

The invention provides a method for breeding insects by using hydroponic plants. The method comprises the following steps of (1) cultivation of host plants, wherein seeds of the host plants are planted onto a hydroponics tank cover plate after being soaked in warm water or a sterilizing agent solution; (2) inoculation of pests, wherein when the height of host plant seedlings is 4.5-5.5 cm, each seedling is inoculated with 5-50 aphids; (3) inoculation of natural enemy insects, wherein stem sections or leaves with the pests are placed on a hydroponics tank and inoculated with the natural enemy insects after 1-2 weeks. The method for breeding the insects by using the hydroponic plants has the advantages that coccinella septempunctata is bred by breeding the aphids using hydroponic broad beanseedlings, water which is treated and repeatedly utilized easily replaces sand which is treated and repeatedly utilized difficultly, and the planting method, a nutrient solution and the hydroponics tank are optimized, thereby providing the simple, efficient and low-cost method for breeding the coccinella septempunctata.

Description

technical field [0001] The invention belongs to the technical field of insect breeding, and in particular relates to a method for cultivating insects with hydroponic plants. Background technique [0002] Bean aphids belong to the family Aphididae of the order Homoptera, and mainly feed on leguminous crops such as beans, peas, and broad beans. Bean aphids have strong fecundity, and one generation can be completed in 4 to 6 days. Each wingless viviparous female can produce more than 100 nymphs, so it is very easy to cause serious damage. [0003] Seven-star ladybug belongs to Coleoptera order Coleoptera and Coccinellidae family Coccinellidae. It has the characteristics of large food intake, large number of eggs, and many annual generations. It is an important predatory natural enemy insect in agricultural production. It can prey on a variety of aphids, whiteflies, leafhoppers, thrips and Lepidoptera insect eggs, larvae (nymphs) and other pests on various crops, vegetables, fr...
