Problems solved by technology

[0003] Aiming at the ecological niche contradiction existing in the existing single-plant bee breeding technology, long bee breeding cycle, labor and time-consuming, and low feeding efficiency, the present invention proposes a high-density feeding method for Aphids aphids, which solves the tenderness characteristic of aphids Contradicts with the ecological niche in the middle and lower part of the egg-laying habit of Aphidius aphidis, and eliminates the contradiction between raising aphids and nutrient carriers

Embodiment Construction

[0008] The number of nutrient carriers per square meter area in the breeding shed is 5 strains per square meter area in the prior art, and about 600 strains per square meter area in the present invention, which is more than 100 times higher than the single plant breeding bee method. Use the group advantage to raise aphids with small seedlings. About 20 days after sowing seedlings, the seedlings are connected with aphids when they are small, and then connected with aphids after 10 days. Due to the group effect and the rapid growth characteristics at the young seedling stage, the influence of aphids on plant growth can be ignored, and the steps of transplanting and cultivating plants can be reduced. The high-density breeding technology of Aphids persicae is used to raise the height of the seedlings of C. persicae, which is lower than 10cm, which is higher than 50cm compared with the height of the single-plant bee propagation method, which effectively eliminates the phenomenon tha...

Abstract

A method of breeding aphidius gifuensis in high-density, in a breeding cote the number of nutrition carriers is about 600 plants in per square meter area, 20 days after sowing and seedling, inoculating the tobacco aphid when the seedling is young, then another 10 days later, inoculating the aphidius gifuensis, about another 15 days apis appears. high-density breeding technology apis feeding cycle of the aphidius gifuensis is 45 days, which can reduce 50 days corresponding to individual apis feeding technology, the aphid feeding amount is 11.2 ten thousand / m[2], the benefit is improved 100.7%, the apis feeding amount is 2.8 ten thousand / m[2], the benefit is improved 60%.

Description

technical field [0001] The invention belongs to the technique of raising insects, and in particular relates to a high-density raising method for aphids aphids. Background technique [0002] The existing technology for raising Aphids persicae is to use radish, tobacco etc. as nutrient carriers to raise A. persicae, and then use A. persicae as a host of C. persicae to raise A. persicae. Because aphids feed on the juice of plants, it will affect the growth of plants. When the plants are small, the growth of the plants will be seriously affected, and the severely affected plants will affect the reproduction of aphids. Using the single-plant bee breeding method, it is necessary to cultivate the plants for a period of time, let the plants grow to a certain extent before feeding them with aphids, so as to reduce the impact of aphids on the growth of the plants, and make full use of the more and larger leaves of a single plant as food for raising tobacco. Aphids, in order to obtain...
