The invention discloses a method for enhancing the RNAi efficiency of lepidoptera insects by adopting dendritic mesoporous silica nanoparticles and application. The method comprises the following steps: mixing dendritic mesoporous silica nanoparticles with a dsRNA solution of a target gene of the lepidoptera insect, carrying out repeated vortex oscillation and on-ice incubation for multiple times to prepare a dsRNA-DMSNs compound, and carrying out RNAi (Ribonucleic Acid Interference) on the insect by adopting the dsRNA-DMSNs compound. The invention also provides an application of the dendritic mesoporous silica nanoparticles for enhancing the RNAi efficiency of the lepidoptera insects, the RNAi efficiency of the lepidoptera insects can be enhanced, and after the dsRNA-DMSNs compound is used for performing RNAi on the insects, isoprocarb or triazophos is applied, so that the sensitivity of the insects to insecticides can be enhanced.

This invention provides a biocatalytic composition for degrading soil organophosphorus residues and its preparation method, belonging to the field of soil remediation technology. The biocatalytic composition provided by this invention comprises: 20-35 parts of a compound microbial agent, 15-25 parts of an organophosphorus hydrolase, 30-45 parts of a soil amendment component, 5-10 parts of a protectant, and 2-6 parts of a synergist; the compound microbial agent is composed of *Pseudomonas aeruginosa*, *Rhizopus oligosporus*, and *Bacillus subtilis*, and the organophosphorus hydrolase is a modified immobilized organophosphorus hydrolase. In the biocatalytic composition of this invention, the compound microbial agent and the modified immobilized enzyme work synergistically to rapidly and efficiently degrade various organophosphorus residues in the soil, such as chlorpyrifos, methyl parathion, and triazophos, achieving a synergistic improvement in soil fertility and remediation effect. It is suitable for in-situ remediation of soil contaminated by organophosphorus pesticides, such as farmland, orchards, and greenhouses.

The utility model relates to the technical field of storage, and discloses a dehumidification structure of a triazophos storage tank, which solves the problems that the triazophos is easily affected with damp and the sealing effect is common during storage, and comprises a storage tank, a tank cover is arranged above the storage tank, and when the triazophos is stored, the tank cover is arranged above the storage tank. The outer sealing ring and the inner sealing ring are used for sealing the outer side and the inner wall of the storage tank correspondingly, after a tank cover is covered, a push rod is manually pushed, a sector plate is stored in a containing groove, a silica gel drying agent is placed on the surface of a separation net, then the sector plate is closed, and the silica gel drying agent conducts dehumidification protection on triazophos in the storage tank through the separation net; then the annular top plate is manually rotated to drive the lead screw to rotate so as to drive the pressing plate to move downwards, the pressing plate is utilized to extrude air in the sleeve and the air storage box, the air is discharged into the air bag in the inner annular plate through the air conveying plate, the air bag bulges to apply pressure to the inner sealing ring from the inside, and finally the purposes of enhancing the sealing effect and removing moisture are achieved.

This invention belongs to the field of pesticide residue detection technology, specifically involving a rapid screening mass spectrometry method for determining the limits of multiple pesticides based on a single pesticide baseline. This method, through the design of "single standard baseline + response ratio database", uses triazophos as the standard pesticide. Through preliminary experiments, a response ratio database between the target pesticide and triazophos is established. During detection, the concentration of multiple target pesticides can be calculated by simply using the response value of triazophos. This effectively solves the pain points of existing rapid screening mass spectrometry detection of multiple pesticides, and is suitable for rapid screening in agricultural products, food and other fields, with broad application prospects.
