Reagent used for inducing frankliniella occidentalis

Abstract

The invention provides a reagent used for inducing frankliniella occidentalis. The reagent comprises (R)-lavender acetate and neryl(S)-2-methylbutyrate or an analogue of neryl(S)-2-methylbutyrate. The induction capability of neryl(S)-2-methylbutyrate can be remarkably improved by (R)-lavender acetate, and the synergistic effect is very strong.

Description

Technical field [0001] The invention belongs to the field of plant protection, and in particular relates to a western flower thrips attractant containing aggregated pheromone components and a field joint application technology with color plates. Background technique [0002] Small insects such as thrips, whiteflies, red spiders, Liriomyza, and aphids cause serious damage to my country's important economic crops, including vegetables and flowers, every year. For example, the western flower thrips (Frankliniella occidentalis) pierce and suck host plant sap with a file-suction mouthpart, which damages young leaves, leaves, floral organs, delays leaf development and flowering, leaves and flowers deformity atrophy and discoloration, or drops flowers and fruits, and harms young The fruit causes scars and deformities. At the same time, it also spreads the serious tomato spotted wilt virus (TSWV). The output of the affected products may decrease significantly, or the quality may deterio...

Problems solved by technology

However, Hamilton et al. believe that the component (R)-lavandulylacetate (R)-lavandulylacetate) found in Western flower thrips has no biological activity and cannot have a separate attractant effect on Western flower thrips

[0005] In addition, the above-mentioned British experts believed in their paper that (R)-lavandulyl acetate ((R)-lavandulyl acetate) and marmoset (S)-2-methylbutanoate (neryl(S)-2-methylbutanoate) No synergistic effects were shown in field trials provided by: (1) (R)-lavandulyl acetate ((R)-lavandulyl acetate) with marmosetyl (S)-2-methylbutyrate The ester (neryl(S)-2-methylbutanoate) was used in a 1:1 ratio using the number of captured western flower thrips and marmoset meat base (S)-2-methylbutanoate (neryl(S)-2-methylbutanoate) alone The captured quantity is basically the same, there is no difference; (2) He determined (R)-lavandulyl acetate ((R)-lavandulyl acetate) and marmosetyl (S)-2-methylbutyrate (neryl (S)-2-methylbutanoate) The ratio range of the two is 1:0.8-1:5. He believes that there is a range of the ratio of the two in nature, and there is no such situation that a specific ratio is the best; (3) he The role of (R)-lavandulyl acetate is believed to be unknown

[0006] In conclusion, the available technology shows that (R)-lavandulyl acetate does not increase the concentration of marmoset (S)-2-methylbutanoate. Effective, no need to mix
