A kind of method for indoor feeding experiment with Spiraea aphid

Abstract

The invention discloses a method for indoor breeding Aphis citricola Van der Goot for experiment. The method comprises the following steps: taking cultivated annual well-grown ashitaba branches, shearing the ashitaba branches to cutting slips which have a length of 10-15cm, 2-5 leaves and inclined shearing wounds, carrying out cutting on the cutting slips, the cutting slips is cultivated in a nursery substrate, when tender shoots grow to 3+ / -0.5 cm, taking Aphis citricola Van der Goots collected on field fruit tree plants back to indoor, and transferring the Aphis citricola Van der Goots ontopart of the ashitaba plants; when the other part of the ashitaba plants is alive for 60 days after the cutting, transplanting the ashitaba plants in to nursery pots, and cultivating the ashitaba plants in an environment of 20-30 DEG C; and when the ashitaba plants is covered with the Aphis citricola Van der Goots, shearing off ashitaba leaves with the Aphis citricola Van der Goots, and transferring the leaves onto the cultivated ashitaba plants. According to the method disclosed by the invention, the ashitaba seedlings are used for feeding and propagating the Aphis citricola Van der Goots forexperiment, the requirements of growth and development and mass propagation of the Aphis citricola Van der Goots for experiment can be well met, and meanwhile, the feeding cost is reduced.

Description

technical field [0001] The invention relates to the field of insect breeding, in particular to a method for indoor breeding of Spiraea aphids for experiments. Background technique [0002] Aphis citricola Van der Goot belongs to Hemiptera of Hemiptera, Aphididae of Aphididae, also known as apple yellow aphid. It is distributed in Japan, North Korea, North America and Central America abroad, and is widely distributed in major apple producing areas in my country. A serious foliar pest. The main hosts of Spiraea aphid are various Rosaceae fruit trees such as apples, pears and crabapples, and plants such as Spiraea and Elmberry. The insect will occur along with the growth period of the young shoots of fruit trees. It will suck the sap of fruit trees and cause the leaves to bend downward or roll horizontally. Fruit quality will cause serious economic losses to fruit tree production. [0003] In the past, most of the Spiraea aphids used in experiments were temporarily collected ...

AI Technical Summary

Problems solved by technology

The indoor cultivation of these woody plants is not easy to survive, and the economic and management costs are high; the growth and development are extremely slow, and the growth rate of the young shoots cannot meet the needs of the expansion and reproduction of the Spiraea aphid; and there are problems such as falling leaves in autumn and winter, and food cannot be continuously provided ; These disadvantages have prevented the preservation and expansion of the Spiraea aphid population indoors
