Embodiment 1

[0019] Silk fibroin-embedded termite drug, the drug includes the following components: silk fibroin, dihydromyricetin, ethametsulfuron, N-succinimide and bifenthrin; the ratio is 1-5:1: 1:100-500:1. The preparation method of the termite medicine embedded in silk fibroin comprises the following steps: 1) mixing silk fibroin and N-succinimide with a molar ratio of 1:50 to 1:500, and dissolving them in 1-fluoro-2,4 - In dinitrobenzene and PBS, mix and react in an ice bath to form a photoactive silk fibroin solution; 2) drop the photoactive silk fibroin solution on the surface of the clean material, add bifenthrin, dihydromyricetin, and sulfamate Long, dihydromyricetin and ethametsulfuron produced unexpected effects through bifenthrin, which has the effect of promoting poisonous killing, so that the drug effect is obvious and the poisonous killing effect is improved. Even if the dose of bifenthrin is low, the drug effect It is also significantly enhanced, and the effect of poison...

[0021] Photoactive silk fibroin synthesis effect monitoring

[0022] In order to confirm that silk fibroin reacts with N-succinimide and produces silk fibroin with active groups, infrared spectroscopy was used to detect the product. The infrared spectrum is closely related to the structure of the molecule. The position and structure of different functional groups in the molecule have different absorption values ​​for the infrared spectrum. The bond length and bond angle of the molecule can be determined by using the infrared spectrum method, and the three-dimensional configuration of the molecule can be inferred from this. It is an effective means to study and characterize the molecular structure. After the silk fibroin is reacted to produce photoactive silk fibroin, its molecular group will inevitably change, and the synthesis of silk fibroin can be verified from the infrared spectrum. Since silk fibroin contains a large number of amino groups (peak value: about 3600) and ca...

[0025] Analysis of material surface structure after grafting new drugs

[0026] Scanning electron microscopy was used to observe the surface structure of the material grafted with new drugs, and analyze the embedding effect of silk fibroin, the distribution and size of the drug after embedding. An electron microscope is an instrument that uses electron beams and electron lenses instead of light beams and optical lenses to image the fine structures of substances at very high magnifications based on the principle of electron optics. The electron beam of the scanning electron microscope does not pass through the sample, but only scans and excites secondary electrons on the surface of the sample, so the image analysis obtained by scanning electron microscope observation is only for the surface structure of the material. From the scanning electron microscope results, it can be proved that the immobilization of silk fibroin film on the surface of the material presents a lamellar sha...

Abstract

The invention discloses a silk fibroin-embedded termite drug and a preparation method and application thereof. The drug is prepared from the following components: silk fibroin, dihydromyricetin, ethametsulfuron, N-succinimide and bifenthrin at the ratio of (1-5):1:1:(100-500):1. The silk fibroin-embedded termite drug obtained through the preparation method has long-acting and slow-release effects, the toxic action on termites is improved and the pollution of the termite drug to the environment is reduced.

Description

technical field [0001] The invention relates to the field of preparation of termite medicine, in particular to silk fibroin-embedded termite medicine and its preparation method and application. Background technique [0002] Termites belong to the subclass Isoptera of the subclass Insecta, mainly including Austermitidae, Grasstermitidae, Woodtermitidae, Rhinotermitidae, Dentotermitidae and Termitidae. Termites are extremely destructive worldwide pests that are distributed all over the world. Their harm involves almost all fields of the national economy, mainly in housing construction, reservoir dams, forest orchards, communication equipment, and cultural relics. [0003] Using chemicals, through certain methods, to directly contact termites, or to treat habitats, breeding places, and harmful objects, so that termites are poisoned and die due to contact or swallowing of chemicals, or because of this, they have a repelling effect and cannot invade and harm. It is characterized...
