Abstract

The invention provides a chitin binding protein Chitinase-like EN03 of diaphorina citri, and belongs to the technical field of pest control. The amino acid sequence of the chitin binding protein Chitinase-like EN03 of diaphorina citri is as shown in SEQ ID NO.1. The invention further discloses a preparation method of the chitin binding protein Chitinase-like EN03 of diaphorina citri. The coding gene of the chitin binding protein Chitinase-like EN03 of diaphorina citri is silenced through RNA interference, so that the diaphorina citri can die due to incomplete ecdysis or unsuccessful ecdysis, and the effect of preventing and treating diaphorina citri is achieved.

Description

Technical field

[0001] The invention relates to the technical field of disease and insect pest control, in particular to the chitinase-like EN03 of citrus psyllid and its coding gene and application. Background technique

[0002] Citri psyllid (Diaphorina citri) belongs to the Hemiptera Psylidae family. It is the main pest in the young shoot stage of citrus. It is also the only vector carrier for the natural transmission of citrus yellow dragon disease discovered in the current research. Citrus Huanglongbing (HLB) is the most devastating disease in the citrus industry in the world, causing huge economic losses to the citrus industry. Strict control of citrus psyllids is a key measure for the prevention and control of citrus yellow dragon disease. The current prevention and control of citrus psyllids are mainly based on chemical control and biological control, that is, chemical insecticides or natural enemy insects and entomopathogenic fungi are used to kill citrus psyllids. The...
