Embodiment 1

[0012] (1) Three chemical substances, 1-heptanol, heptanal and pentadecanol, are fully mixed in a proportion of 1:1:1 to obtain a chemical substance mixture.

[0013] (3) Weigh 0.5 ml of the above chemical substance mixture, dissolve it in 999.5 ml of mineral oil, and fully stir to obtain a locust antifeedant.

[0014] (3) Put it in a container and seal it for later use.

Embodiment 2

[0016] The antifeedant activity of the antifeedant of the present invention to locusts.

[0017] The locusts were reared at a temperature of 28°C to 30°C and a relative humidity of 60%, and were fed once a day with fresh corn leaves and wheat. A non-selective antifeedant activity assay was used. Cut 2 x 3cm 2 Put the corn leaves in a petri dish for later use and moisturise with filter paper. When the leaf surface is dry, apply the antifeedant solution to be tested evenly on the leaf surface from low concentration to high concentration with a pipette gun, drop 25 μl of the medicinal solution on each leaf, and use a pin with a hard triangular piece inserted after the leaf surface is dry. The leaves were fixed and put into a 250ml plastic cup (1 leaf / cup), and one test worm was placed in each cup with leaves. After covering the mouths with mesh cloth, they were all raised in a fluorescent lighting room (temperature 28°C-29°C, humidity about 70%). The leaves were taken out aft...

Abstract

The invention discloses a locust antifeedant as well as a preparation method and application thereof. According to the application of the locust antifeedant in the field of locust prevention and treatment, the locust antifeedant is used for preventing and treating locusts, can be applied to plant surfaces, surrounding environments or prevention and treatment areas in which which locusts like to eat, prevents locusts from eating plants and controls locust behaviors so as to achieve prevention and treatment effects, protect the environment and crops, and prevent the yield and economic loss. Because the chemical compounds are derived from plants, the locust antifeedant has no toxic or harmful effects on the environment, human, livestock and poultry, is safe to natural enemies, and has the characteristics of small dosage, obvious effect, no environmental pollution, simplicity and convenience in application, high-efficiency crop protection and the like.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a locust antifeedant and a preparation method and application thereof. Background technique [0002] Locusts are a major pest that seriously threatens my country's agricultural and animal husbandry production, commonly known as grasshoppers. Feeding on crops is the main damage behavior. Controlling its feeding will reduce and avoid the harm of locusts to agriculture and ensure the sustainable development of agriculture. However, there is no antifeedant product for locusts at present. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a kind of locust antifeedant and preparation method and application thereof, the application of locust antifeedant in the field of locust control, for preventing and controlling locusts, can be applied to the plant surface, surrounding environment or control area that likes to feed, Prevent locusts from eating...
