Embodiment 1

[0012] In this embodiment, a short peptide with anti-aphid synergistic effect is synthesized by solid-phase chemistry, and the amino acid sequence of the short peptide is SEQ ID No: 01, that is, Asn Ser Ser Val Ser Ile Ile.

Embodiment 2

[0014] The application of the short peptide in Example 1 in the prevention and control of aphids is mainly used to enhance the aphidicidal effect of chitinase.

[0015] The specific operation is to use the short peptide together with chitinase, and the concentration ratio of the short peptide and chitinase is 2:1.

Abstract

The invention discloses an anti-aphid synergic oligopeptide and an application thereof. The oligopeptide can be used for preventing and controlling aphids. As a chitinase anti-aphid synergic oligopeptide, the anti-aphid synergic oligopeptide solves the problem that chitinase is insufficient in inhibiting effect to aphids.

Description

technical field [0001] The invention relates to an anti-aphid synergistic short peptide and its application. Background technique [0002] Aphids are small piercing-sucking insects that can harm grain, cotton, tobacco and other plants through feeding, honeydew pollution, and virus transmission, causing plant growth retardation and wilting, and inducing various viral diseases, Black mold, etc., can cause plant death in severe cases, and are important agricultural and forestry pests. Therefore, the control of aphids has the dual significance of controlling insects and preventing diseases. [0003] Chitinase is an enzyme that catalyzes the hydrolysis of chitin to generate N-acetylglucosamine. Some chitinases have an inhibitory effect on aphids, but the inhibitory effect is not obvious, and it cannot be practically applied to crops to produce anti-aphids. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art...
