The technical field is as follows:

the utility model relates to a simple and easy device of oranges and tangerines psylla is raised to single seedling.

Background art:

diaphorina citri, homoptera, psyllidae. Nymphs are 5 years old, and adults are about 3 mm long, and are a type of pest harmful to oranges. Most adults lay eggs on young shoots of host plants, and young shoot juice is sucked after nymphs hatch until the adults emerge. The damaged host has withered and deformed young shoots. The white honeydew secreted by the diaphorina citri can adhere to branches and leaves and can cause the occurrence of soot diseases. More importantly, the diaphorina citri is a transmission vector for citrus greening disease. The diaphorina citri is fed and spawned on the citrus yellow shoot infected plants for propagation, so that a large amount of bacteria-carrying imagoes can be generated, and the imagoes can spread the citrus yellow shoot through healthy plants. Therefore, the study on the life habit and the feeding characteristics of the diaphorina citri is beneficial to disclosing the relationship between insects and plants and provides a basis for pest control.

The amphigamy, oviposition, single worm life history and infectious diseases experiment of insects are important research contents for researching the behavior of the diaphorina citri.
