Method for propagation of aphidius gifuensis for multiple times by using tobacco plants

Abstract

The invention belongs to the technical field of biological prevention and control for agriculture and forestry pests, and particularly relates to a method for propagation of aphidius gifuensis for multiple times by using tobacco plants. The method comprises the following steps of breeding of myzus persicae host plants, propagation of the aphidius gifuensis for the first time, propagation of the aphidius gifuensis for the second time, propagation of the aphidius gifuensis for the third time, and propagation of the aphidius gifuensis for the fourth time. The method has the advantage that the developed root system of a tobacco plant is sufficiently utilized, and new leaves are promoted to germinate and quickly grow, so that the tobacco plant can be reutilized, the secondary seedling cultivation and transplanting can be avoided, the labor intensity is decreased, the time is saved, and the propagation efficiency of the aphidius gifuensis is greatly improved.

AI Technical Summary

Benefits of technology

This technology allows crop plantings such as lamina or bracteous tissue (tobaccos) to become more valuable by being reused instead of discarding them after use. By growing these crops back into their original form they may also have potential uses beyond just producing honeycomb products like paper pulp without having to repeatedly grow new ones again. Additionally, this method helps reduce stress on both indoor gardeners who work alongside greenhouse vegetables during winter months due to reduced water usage compared to traditional methods that involve breeding old seeds from other species.

Problems solved by technology

This patents discuss how insect vectors cause damage to vegetable crop products like potatoes (Solanum tuberosums) during harvesting processes due to lack of oxygen from sunlight exposure. To prevent this problem, various techniques have been developed including gene silencing with specific genes targeting these viruses. However, current approaches require multiple steps before plantation, leading to longer cycles between generations. Therefore, researchers want more reliable and cost-effective way to manage damaging organisms called Asian Soft Yellow Stings (ASY).
