Embodiment 1
[0025] The growth time required for different host plants to meet the requirements of use
[0026] Host plants for testing: potted mung beans, kidney beans, cowpeas, broad beans, and cotton; hydroponic mung beans, cowpeas, broad beans, and cotton, and record the required growth time when the requirements for use are met (Table 1).
[0027] Table 1 The minimum growth time table required when different host plants meet the requirements of use
[0028]
[0029] Note: " / " in the table indicates that the germination rate is too low to be suitable for hydroponics
Embodiment 2
[0031] Effects of different host plants on the growth and development of Lygus melanogaster
[0032] Host plants for testing: potted cowpea, broad bean, and cotton, which are used as test plants after they have grown into plants; hydroponic mung bean seedlings are used as test plants when they are 8-10 cm high; green beans are purchased from the market and treated with sodium hypochlorite (10%) Soak for 30 minutes, then disinfect with 75% alcohol, and dry it for later use.
[0033] Insects to be tested: the newly hatched Lygus nymphs of the same size and size were selected as the insects to be tested.

Abstract
The invention discloses a method for breeding adelphocoris suturalis. Mung bean seedlings serve as food of adelphocoris suturalis. The mung bean seedlings are placed in a nymph breeding cage and replaced with a batch of new mung bean seedlings every 3-5 days. Adult insects are transferred into an oviposition cage 24 hours after eclosion of the adelphocoris suturalis. Two oviposition frames are placed in the oviposition cage. Three to five layers of filter paper are laid in each sterile glass culture dish and placed on the oviposition frames in the oviposition cage, the filter paper is kept moist so that the adelphocoris suturalis can lay eggs on the filter paper, and the mung bean seedlings are replaced with a batch of new mung bean seedlings every 4 days to be eaten by the adult insects. The culture dishes and the filter paper are replaced once every 2 days, the filter paper obtained after oviposition is taken out and placed in an artificial climate chamber, the eggs are hatched after 5-7 days, and then the filter paper is transferred into the nymph breeding cage. The adelphocoris suturalis bred through the method is low in nymph death rate, high in adult insect weight and good in hunger resistance.
Description
technical field [0001] The invention relates to an artificial multiplication method of insects, in particular to an artificial multiplication method for raising piercing-sucking mouthparts insects, Lygus mesida, with living host plants. Background technique [0002] The middle black Lygus belongs to the Hemiptera Miridae family Lygus sativa. It is small and medium in size, with a body length of 6-7mm and a width of 3-4mm. In the Yellow River Basin, there are 4 generations in a year, and in the Yangtze River Basin, there are 4-5 generations in a year. The main harmful plants are cotton, wheat, barley, broad bean, mung bean, castor, soybean, sunflower, sweet potato, rape, alfalfa, milk vetch, Melilotus osmanthus, carrots, canada, mugwort, etc. [0003] The life history and biological characteristics of Lygus black bug in indoor research are the prerequisites for the study of its control technology, and how to obtain a sustainable source of insects through economical, simple a...
