Abstract
The invention relates to a antifeedant composition and application thereof in aphid control. The antifeedant composition comprises Polygonum tinctorium dialdehyde, methyl salicylate and citronellal.
Description
Technical Field
The invention relates to the field of pest control, in particular to a antifeedant composition for controlling aphids.
Background
The aphids are fast in breeding, short in generation and strong in drug resistance, so that control is difficult, and the use of traditional chemical pesticides can cause serious environmental pollution, so that development of environment-friendly plant-source pesticides for control is urgently needed.
Disclosure of Invention
One of the present invention provides a antifeedant composition comprising Polygonum dialdehyde, methyl salicylate and citronellal.
In a specific embodiment, the molar ratio of the polygonal dialdehyde, the methyl salicylate and the citronellal is (3-5): 2:1.
In a specific embodiment, the molar ratio of Polygonum tinctorium dialdehyde, methyl salicylate, and citronellal is 3:2:1 or 5:2:1.
In a specific embodiment, the antifeedant composition further comprises a solvent.
In one embodiment, the solvent is a 50% aqueous ethanol solution.
The invention provides a use of a antifeedant composition according to any one of the invention for aphid control.
In a specific embodiment, the aphid is a pea aphid.
The invention has the beneficial effects that:
the antifeedant of the plant source is easy to degrade in the nature, has no residual problem, is safe and friendly to the environment, is different from the action mechanism of the nerve agent, prevents and controls pests by inhibiting feeding behavior of insects, has good selectivity to the pests, can avoid injury to non-target organisms, and has important ecological benefit.
The antifeedant composition has good antifeedant effect on aphids, wherein the effective component is a plant source compound, and the antifeedant composition can be used for green control of aphids.
Drawings
Fig. 1 is a graph of the antifeedant rates of aphids treated with different antifeedants, the a, b, c, d, e same letter indicating that the difference is not significant at the α=0.05 level, and the different letter indicating that the difference is significant at the α=0.05 level.
Wherein Solvent represents Solvent (50% ethanol aqueous solution), citron represents citronellal, meSA represents methyl salicylate, poly represents Polygonum tinctorium dialdehyde, and 1:1:1, 1:2:3 and 1:2:5 represent molar ratio of citronellal, methyl salicylate and Polygonum tinctorium dialdehyde, respectively.
Detailed Description
The above-described aspects of the invention are described in further detail below in the form of preferred embodiments, which are not to be construed as limiting the invention.
Reagents for use in the examples of the invention are commercially available unless otherwise specified.
Polygonum dialdehyde, methyl salicylate and citronellal are commercially available.
Example 1
Preparation of a single-dose solution: citronellal, methyl salicylate and Polygonum dialdehyde were prepared with 50wt% aqueous ethanol to give solutions of citronellal, methyl salicylate and Polygonum dialdehyde, respectively, at a concentration of 1 mg/mL.
Preparing a mixed solution: the citronellal solution, the methyl salicylate solution and the polygonum dialdehyde solution are mixed in a molar ratio of 1:1:1, 1:2:3 and 1:2:5 to form two mixed solutions.
A50 wt% aqueous ethanol solution was used as a blank.
The leaf dish device is formed by reforming a culture dish: uniformly punching 4 round holes with the diameter of 1.0cm on the bottom of the culture dish with the diameter of less than 9cm, and sequentially connecting the circle centers of the 4 round holes to form a square, which is called a blade cover plate; 25mL of 16g/L agar substrate is filled at the bottom of a culture dish with the diameter of 9cm and used for moisturizing the leaves; the broad bean leaves are made into round leaves with the diameter of 1.5cm by using a puncher, the backs of the 4 round leaves are paved on an agar substrate upwards, the circle centers of the 4 round leaves are sequentially connected to form squares, a leaf cover plate is covered on the agar substrate paved with the leaves, and the 4 round leaves are exposed from the 4 round holes of the cover plate to form a leaf dish. A50 wt% aqueous ethanol solution was applied to two blades forming a diagonal line with a small brush, and a Polygonum dialdehyde solution of the same concentration was applied to the other two blades forming a diagonal line with a small brush so as to exclude the influence of factors such as azimuth in the environment, and 10. Mu.L of each blade was applied. After the solvent has been completely air-dried, each leaf dish is inoculated with 20 5-day-old pea aphids to be tested, covered with a dish cover of a petri dish, in order to prevent the pea aphids from escaping. The 20 test insects are one biological repetition and total 6 repetitions. The number of feeding Pisum sativum aphids on each treatment leaf at 6h was recorded and counted, and the feeding refusal index was calculated. Index number Antifeedant Index (AI) = (number of caterpillars on negative control leaf-number of caterpillars on treatment leaf)/(number of caterpillars on negative control leaf + number of caterpillars on treatment leaf). The results are shown in FIG. 1.
As can be seen from fig. 1, when citronellal, methyl salicylate, and Polygonum dialdehyde were mixed in a molar ratio of 1:2:3 and 1:2:5, the number of index fingers was significantly higher than the three compounds treated alone and in other mixing ratios, indicating that the three compounds produced a synergistic effect, producing unexpected technical effects.
