A process for producing three recombinant enzymes capable of hydrolyzing each class of organophosphate, carbamate, and pyrethroid insecticides, as well as a formulation containing these enzymes provides the recombinant plasmid DNA vector, in which the protein secretory system has been modified to enhance the secretion of recombinant protein into the periplasmic space or culture medium. A nucleotide sequence encoding PelB (pectate lyase B) signal sequence for periplasmic localization is deleted and replaced with a nucleotide sequence encoding LamB (maltoporin or phage lambda receptor) signal sequence to enable a more efficient secretory recombinant protein. Three recombinant plasmid DNA vectors for the expression of recombinant proteins that are constructed using the modified plasmid DNA vector described above. The recombinant proteins include a recombinant organophosphate-hydrolyzing enzyme; a recombinant carbamate-hydrolyzing enzyme; and a recombinant pyrethroid-hydrolyzing enzyme.

The invention relates to a process for the preparation of synthetic pyrethroid insecticides. The process involves coupling of carboxylic acid (IV) with an alcohol (V) in the presence of a catalyst. wherein R1, R2, R3 and Ar are defined in the specification.

The present application relates to a composition containing pyrethroid insecticide and its application. The composition has synergistic effect of cycloxaprid and pyrethroid insecticide, which can improve the effect of pest control, reduce the amount of pesticide application, reduce the frequency of use, and reduce the cost of use.

The invention relates to a magnetic solid-phase extraction method for pyrethroid insecticides in fruits and vegetables based on a Fe3O4-coated CS-coated AA material. The magnetic solid-phase extraction method comprises the following steps: S1, synthesizing a Fe3O4-coated CS-coated AA magnetic adsorbent; s2, preparing a fruit and vegetable sample; s3, magnetic solid phase extraction; s4, determining by using a gas chromatography-mass spectrometry method; fe3O4 nano magnetic particles are embedded in chitosan gel, then acrylic acid is grafted on chitosan molecules for modification, the Fe3O4 CS AA magnetic adsorbent is prepared through glutaraldehyde curing and crosslinking, and based on the fact that the chitosan molecules contain a large number of-OH and-NH2 and-COOH active groups in acrylic acid, the Fe3O4 CS AA magnetic adsorbent and pyrethroid pesticide compounds form intermolecular hydrogen-bond interaction, so that the magnetic adsorbent can be used for adsorbing the pyrethroid pesticide compounds. Therefore, target component extraction is realized, and the method for determining deltamethrin and cyhalothrin pesticide residues in fruits and vegetables by combining magnetic solid-phase extraction with gas chromatography-mass spectrometry is established.
