Problems solved by technology

At present, chemical pesticides are mainly used to control silver spider moths, but because chemical pesticides have brought huge pollution to humans and the environment, excessive use can easily cause silver spider moths to develop resistance. Therefore, it is necessary to look for pests that are cost-effective and compatible with the environment New prevention and control methods and new technologies are an urgent need to solve the current environmental pollution and food safety crisis

Embodiment 1

[0021] Embodiment 1 cis-7-dodecene-N, the preparation of N-dimethylcarbamate:

[0022] Synthetic route such as Figure 4 As shown, put 0.5g Z7-12:OH (2.71mmol) into a 100mL round-bottom single-necked flask, add 15mL of redistilled N,N-dimethylformamide (DMF), and bind 0.56g (4.07mmol) Acid K 2 CO 3 . A solution of dimethylcarbamoyl chloride (4.07 mmol) in DMF was slowly added dropwise. After dropping, react overnight at room temperature, and monitor with TLC during the reaction. The reaction was quenched with deionized water, extracted with ethyl acetate (10mL×3), the extract was washed with saturated brine (15mL×3), dried over anhydrous magnesium sulfate, concentrated under reduced pressure, and the crude product was purified by silica gel column chromatography to obtain cis-7-dodecene-N,N-dimethylcarbamate.

[0023] cis-7-dodecene-N,N-dimethylcarbamate (Z)-dodec-7-en-1-yldimethylcarbamate, light yellow oily liquid, yield 62%; 1 H NMR (300MHz, CDCl 3 )δ:5.34-5.30(m,2H...

Embodiment 2

[0024] Embodiment 2 field biological activity determination test

[0025] Lure preparation:

[0026] The n-hexane solution containing the sex pheromone is added in proportion to the anti-mouth rubber head to obtain the sex pheromone lure core (SP) containing silver spodoptera. Then add different sex pheromone analog components to the lure. After the solution has completely penetrated into the trans rubber head, add 100 μL of n-hexane. lure. Each of the above-mentioned lure treatments was set up with 5 repetitions. As a control, the lure blank treatment (CK) and the barrel trap containing three live female silver-cutting moths (PE) that had not mated for 3 to 5 days were 5 each. repeat.

[0027] The prepared lure cores were placed in barrel traps and placed in areas where silver armyworm occurred seriously. In order to further illustrate the feasibility of the present embodiment, 22 specific formulas are provided in table 1:

[0028] Table 1 Treatment numbers of different ...

Abstract

The invention discloses a composition for controlling Macdunnoughia crassisigna Warren and application of the composition. The composition disclosed by the invention comprises a sex pheromone and a sex pheromone analogue of the Macdunnoughia crassisigna Warren, wherein the sex pheromone is cis-7-dodecenyl acetate, cis-9-tetradecenyl acetate and cis-11-hexadecen-1-ol; the sex pheromone analogue isone or more than one of cis-7-dodecenyl-N-methylcarbamate, cis-7-dodecenyl-N,N-dimethylcarbamate and cis-7-dodecenyl-N-methyl-N-ethylcarbamate; the mass ratio of the sex pheromone to the sex pheromoneanalogue is 1: (0.01-0.1). The composition provided by the invention can trap and kill male moths of Macdunnoughia crassisigna Warren more effectively, reduce the mating frequency and reduce the propagation rate, thereby achieving the purpose of efficiently controlling Macdunnoughia crassisigna Warren. The composition has the advantages of low consumption and environmental friendliness, can be accurately applied to insect condition prediction, mass trapping and mating interference, and has important meanings for comprehensive treatment of Macdunnoughia crassisigna Warren.

Description

technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to a composition for preventing and controlling silver moth and its application. Background technique [0002] Macdunnoughia crassisigna Warren belongs to Lepidoptera, Noctuidae, and is a leaf-eating pest. In my country, it poses a serious threat to cotton, peanuts, corn, soybeans and cruciferous vegetables, and is one of the most destructive agricultural pests in our country. Silver ingot moth has 2-4 generations in my country, and its larvae damage different hosts in different periods. It mainly damages crops such as cotton and beans in spring, corn and soybeans in summer, and cruciferous vegetables in autumn. The worm often co-occurs together with common pests such as diamondback moth and cabbage caterpillar in cruciferous vegetable fields. The newly hatched larvae mostly cluster on the back of the leaf and eat the mesophyll, leaving the upper epidermis, ...
