Embodiment 1

[0017] The reagent concentrations used were:

[0018] 1) 0.1ng / μL DMNT solution, the solvent required for dilution is water.

[0019] 2) 0.5ng / μL DMNT solution, the solvent required for dilution is water.

[0020] The preparation method of the above solution: first prepare 100mg / mL DMNT / DMSO solution, mix DMNT and DMSO, oscillate to mix evenly, dissolve DMNT powder, configure it into a liquid solution, and then dilute the solution with water to the above concentrations , thereby making the whitefly oviposition repellant of the present invention.

[0021] 1. Bemisia tabaci MED is raised on tomato plants in the greenhouse. The tomato variety used is Cyclamen No. 8. The whole plant is placed in a cage (60cm×60cm×60cm), the temperature is 25±2°C, and the humidity is 65± 5%, light rhythm 16L:8D. The source of MED insects was collected from a greenhouse in Beijing, and identified as MED by mitochondrial cytochrome oxidase I (mtCOI) gene. A pair of newly emerged adults was select...
