Embodiment 1

[0026] Example 1 Preparation of plant extracts.

[0027] Take 10 parts of dried Luo Han Guo and 30 parts of fresh Korla fragrant pears, mash them with a tissue grinder, mix them evenly, place them under aerobic conditions at 60 degrees Celsius for 24 hours, and filter them with 3 layers of gauze. Turn the centrifuge to centrifuge for 30 minutes and take the supernatant to obtain the desired plant extract.

Embodiment 2

[0028] The preparation of embodiment two aromatic thrips attractants

[0029] Get 10 parts of eugenol, 5 parts of nerolidol, 50-100 parts of the plant extract that embodiment 1 makes, 5 parts of sec-butyl acetate, 5 parts of fatty alcohol polyoxyethylene ether, place after mixing evenly The aromatic thrips attractant was obtained by shearing with a shearing machine at 8000 rpm for 30 minutes.

Abstract

The invention discloses a fragrant thrip attractant. The fragrant thrip attractant comprises an assistant, and effective components of the fragrant thrip attractant contain plant extract, nerol and eugenol. A mass part ratio of the eugenol to the neroli to the plant extract is 2:1:(10-20). The plant extract is extracted from a mixture of Fructus Momordicae and Korla pears. The plant extract, the neroli and the eugenol are mixed according to a certain ratio to achieve a very good attraction effect on thrips and significantly improve the thrip prevention and control effect of agricultural compounds, so the fragrant thrip attractant has wide application potential.

Description
