Problems solved by technology

However, the long-term use of traditional pesticides will inevitably lead to the resistance of the green and black ligus, forcing farmers to increase the amount of pesticides to control pests, which seriously threatens the safety of agricultural products and the ecological environment.

Embodiment 1

[0016] Preparation of 1-substituted phenyl-5-(β-ionone ring)-1,4-dien-3-one compound

[0017] Add β-ionone (0.88 g, 4.6 mmol), substituted benzaldehyde (6.0 mmol) and ethanol (10 mL) into a 50 mL round bottom flask, stir, and slowly add 15 mL of sodium hydroxide aqueous solution (1.0 mol / L ), reacted at room temperature for 5 hours. After the reaction was completed, the pH of the reaction solution was adjusted to 7.0 with 10% hydrochloric acid aqueous solution. Extract with ether, combine the organic phases, concentrate, and separate by column chromatography [V (petroleum ether) / V (ethyl acetate) = 13:1-25:1] to obtain 1-substituted phenyl-5-(β-violet Keto ring)-1,4-dien-3-one.

Embodiment 2

[0019] The preparation method of the lure core of the lure of the green stinkbug and the black stinkbug

[0020] The 1-substituted phenyl-5-(β-ionone ring)-1,4-dien-3-one compound prepared in Example 1 was dissolved in dichloromethane, and the solution was added to the rubber lure (per A rubber lure contains 0.2-20 mg of drug), and after the solvent is volatilized, clean dichloromethane is added to fully infiltrate the drug into the rubber. After the solvent evaporates again, wrap the lure with tinfoil, put it in a ziplock bag and store it in a -4°C refrigerator for later use.

Embodiment 3

[0022] Application method of attractants of Lygus green and Lygus melanogaster

[0023] From July 16, 2012 to July 27, 2012, the trapping test of Lygus spp. and Lygus chinensis were carried out in the alfalfa field in Xinxiang Base, Henan Province. Alfalfa fields with consistent growth, consistent management conditions, and large and neat plots were selected as experimental fields. The lures prepared above were fixed on boat-shaped traps, and the boat-shaped traps were placed flush with the top of the crops. The distance between adjacent traps was 10 m. Three replicates were set up for each treatment, arranged randomly. After setting up, investigate the number of trapping Lygus and black Lygus every three days. The results are shown in Table 1.

Abstract

The invention discloses an Apolygus lucorum Meyer-Dur and Adelphocoris suturalis jakovlev attractant belonging to the technical field of insect attractant preparation. The Apolygus lucorum Meyer-Dur and Adelphocoris suturalis jakovlev attractant is a 1-substituted phenyl-5-(beta- ionone ring)-1, 4-diene 3-ketone compound and is shown in formula (I). The invention provides a synthetic method of the 1-substituted phenyl-5-(beta- ionone ring)-1, 4-diene 3-ketone compound, the preparation method and application of Apolygus lucorum Meyer-Dur and Adelphocoris suturalis jakovlev attractant lure. The Apolygus lucorum Meyer-Dur and Adelphocoris suturalis jakovlev attractant is simple in preparation method and has the advantageous effects of being efficient, inexpensive and pollution-free to trap and kill.

Description

technical field [0001] The invention belongs to the technical field of preparation of insect attractants, and in particular relates to an attractant for a class of Lygus spp. Background technique [0002] Apolygus lucorum Meyer-Dür and Adelphocoris suturalis Jakovlev are two important stink bugs that seriously endanger crops in my country. They have a wide range of hosts, including cotton, beans, alfalfa, artemisia, flowers, medicinal plants, cruciferous vegetables, etc. Adults and nymphs of Lygus green and Lygus chinensis both harm crops, and their damage and spread are extremely strong. [0003] In recent years, after the large-scale planting of transgenic Bt cotton in the Yellow River Basin and the Yangtze River Basin, the frequency and amount of pesticide spraying have been significantly reduced, which indirectly led to the living space of the green Lygus and the black Lygus, and the populations increased sharply. Moreover, as the green Lygus and the black Lygus contin...
