Problems solved by technology

[0004] Because aphids feed on the juice of plants will affect the growth of plants, when the plants are small, the growth of the plants will be seriously affected, and the aphids will be raised after the plants have not grown to a certain level. The aphids have a great impact on the growth of the plants. The feeding amount cannot be increased. When the reproduction amount of aphids reaches a certain amount, the effective opportunity to use aphids as a carrier to raise aphids is not seized, and due to the tenderness characteristics of aphids and the habit of laying eggs of aphids, they are in the middle and lower parts. Contradictions, resulting in low feeding efficiency of aphids and aphids

Embodiment 1

[0018] Embodiment 1: utilize potato as the method that host cultivates Aphididae, it comprises the steps: A kind of method that utilizes potato as host to cultivate Aphidia, it comprises the steps:

[0019] (1) Cultivate host potato seedlings. During the process of host potato seedlings, prepare nutrient soil according to the following weight percentages: 60% soil, 20% fine sand, 20% bio-organic fertilizer, mix well and sieve, and add 1.5% superphosphate fertilizer -3%, diammonium phosphate 3%, mix evenly, kill insects and disinfect the nutrient soil, then put the nutrient soil into the potato cultivation pot, the size of the potato cultivation pot is equivalent to the flower pot in the prior art, and can also be replaced by a flower pot , it is advisable to cut 50 pieces per kilogram of seed potatoes. When cutting into pieces, first cut longitudinally and then cross-cut. The size of the cut pieces is required to be uniform. Each piece has 1-2 buds. Rinse several times, then u...

Abstract

The invention discloses a method for culturing aphidiidae by using potatoes as hosts. The method comprises the following steps: culturing host potato seedlings, transplanting the potato seedlings to a potato aphid room, inoculating 10-11 potato aphids to true leaves of each potato plant when 5-6 true leaves of each potato plant grow up, enabling the potato aphids to spread and reproduce naturally, moving the potato seedlings into an aphidiidae room, inoculating aphidiidae into the aphidiidae room, and promoting the aphidiidae in the aphidiidae room to lay eggs for parasitism inside the potato aphids, thereby obtaining stiffened potato aphids. By adopting the method that potatoes are adopted as the hosts to culture aphidiidae, the reproduction cost can be greatly lowered when being compared with that of a method that cigarette seedlings are adopted as the potato aphid hosts since the potatoes are low in cost, rapid to grow and high in potato aphid reproduction rate.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to a method for cultivating aphids by using potatoes as hosts. Background technique [0002] Aphids parasitize on the plants of Solanaceae, Cruciferae, Compositae, Fabaceae, Chenopodiaceae, Convolvulaceae, Rosaceae and other crops. When the tobacco seedlings are transplanted into the field, the winged aphids in the vegetable field will migrate Flying to the tobacco plants, a high-incidence period is formed from late April to early May. If the aphid sucks the juice in the plant, the leaves will shrink and turn yellow, the stems and pedicels will be twisted and deformed, and the plants will be short. Viral diseases, aphids are more harmful in agricultural and forestry production. [0003] The method of controlling aphids by aphids is to cultivate special tobacco seedlings first, and then introduce aphids to grow and reproduce on the tobacc...
