Abstract
The invention relates to an oxybasis glauca extract product and an application of oxybasis glauca in trapping of prodenia litura, which belongs to the technical field of the biological prevention and treatment of insect pests. The content of the invention comprises the following steps: crushing the fresh oxybasis glauca leaves and immersing for 1-96 hours by absolute ethyl alcohol with ratio of 1:2-1:8 times (w/w), extracting for 1-30 minutes by auxiliary of supersonic wave, filtering an ethanol leaching liquor, and performing vacuum concentration at 25-50 DEG C to obtain an oxybasis glauca ethanol extract product, dissolving the oxybasis glauca ethanol extract product by absolute ethyl alcohol to prepare an oxybasis glauca extract product solution, and injecting the oxybasis glauca extract product solution into a silicone rubber carrier trapping the prodenia litura. The oxybasis glauca extract product has strong trapping effect, has the advantages of high activity and long persistent period, and has good trapping effect to prodenia litura. The invention provides a novel biological prevention and treatment method for prodenia litura.
Description
Technical field
The present invention relates to a Plant Extracts in the application luring in collection prodenia litura, be specifically related to a kind of chenopodium glaucum linn extract in the application luring in collection prodenia litura, belong to biological control of insect pests technical field.
Background technology
Chenopodium glaucum linn (Chenopodium glaucum) is Chenopodiaceae annual herb plant, is distributed widely in global Temperate Region in China, is born in by the limit, farmland, water channel ditch of height above sea level 540-1400m, wasteland, Plain, mountain valley etc.
About the application of chenopodium glaucum linn, south China is among the people to be had and sets it as the edible custom of edible wild herbs.Chenopodium glaucum linn can also be used as medicine, and has effect of clearing heat and promoting diuresis.Chenopodium glaucum linn belongs to weeds in field, and the research of its application in agricultural pest control is less, and so far there are no about chenopodium glaucum linn extract for luring the relevant report of collection prodenia litura.
Prodenia litura (Spodoptera litura) is a kind of universal Important Agricultural insect of Lepidoptera Noctuidae.China is except Qinghai, Xinjiang are not bright, and each province (autonomous region) has generation.The blade of nearly 300 Plants such as larval feeding sweet potato, cotton, taro, lotus, sesbania, soybean, tobacco, twill and Cruciferae and solanaceous vegetable etc., the serious harm crops yield and quality that particularly vegetables produce.About the control main dependence chemical control at present of prodenia litura, for the insecticide of prodenia litura control, food security and ecotope are all had to very important negative effect.
Insect baiting technique is the green prevention and control technology advocated of country in recent years, and its principle is the insect that lures collection field by discharging special volatile chemical, concentrates after it is assembled and kills, and reaches the object of pest control.For luring the substance classes of collection prodenia litura very limited, research and develop the novel inducing agent of prodenia litura at present, to the biological control of prodenia litura, significant.
The inventor's the experimental results shows, chenopodium glaucum linn ethanol extract has good attractive effect to prodenia litura.By literature search, have no the open source literature report identical with the present invention.
Summary of the invention
The present invention has overcome the deficiency to chenopodium glaucum linn purposes understanding and practice, and the application of chenopodium glaucum linn control prodenia litura is provided.
The present invention is achieved in that
A kind of chenopodium glaucum linn extract, the present invention is characterised in that: this chenopodium glaucum linn extract is the ethanol extract of chenopodium glaucum linn leaf, concrete grammar is, fresh chenopodium glaucum linn blade is pulverized, be 1: 2～1: 8 times according to weight ratio and add soaked in absolute ethyl alcohol 1～96 hour, then ultrasonic assisted extraction 1～30 minute, after filtering by alcohol extract in 25～50 ℃ of reduced pressure concentrations, obtain the ethanol extract of chenopodium glaucum linn.
The preferred way of ethanol extract of this chenopodium glaucum linn leaf is, fresh chenopodium glaucum linn blade is pulverized, be 1: 4 times according to weight ratio and add soaked in absolute ethyl alcohol 48 hours, then ultrasonic assisted extraction 10 minutes, after filtering by alcohol extract in 40 ℃ of reduced pressure concentrations, obtain the ethanol extract of chenopodium glaucum linn.
Chenopodium glaucum linn extract lures a concentrated application prodenia litura, and the present invention is characterised in that, using the ethanol extract of chenopodium glaucum linn leaf with absolute ethyl alcohol as dissolution with solvents, make content and be 1～40% chenopodium glaucum linn leaf ethanol extract solution, for luring collection prodenia litura.
Beneficial effect of the present invention is:
1, the utilization of chenopodium glaucum linn has been had to brand-new understanding, for prodenia litura control provides a kind of novel inducing agent.
2, chenopodium glaucum linn ethanol extract has strong attractive effect to prodenia litura, active high, the lasting period is long, and prodenia litura is had to the good collection effect that lures.
Below in conjunction with specific embodiment, the present invention is further explained.
