Abstract
The invention belongs to the technical field of plant protection attractants and particularly relates to a cotton aphid natural enemy attractant and a preparation method thereof, mainly aiming at solving the technical problems of existing chemical prevention and control of cotton aphids that the pesticide resistance of the cotton aphids is enhanced, the environment is seriously polluted and the cotton aphid prevention and control cost is high. According to the technical scheme provided by the invention, the cotton aphid natural enemy attractant is prepared from the following components by mass percent: 1.0-5.0% of methyl salicylate, 0.0-3.0% of phenylacetaldehyde, 0.0-3.0% of alpha-terpilenol, 0.01-0.1% of 2,6-di-tert-butyl-4-methylphenol (BHT), 60-80% of absolute ethyl alcohol and the balance of distilled water. The preparation method comprises the following steps: dissolving 2,6-di-tert-butyl-4-methylphenol (BHT) into absolute ethyl alcohol and adding methyl salicylate, phenylacetaldehyde and alpha-terpilenol, and uniformly stirring; finally, adding distilled water and uniformly mixing to prepare the cotton aphid natural enemy attractant; and filling a bag made of a hot sealing aluminum foil composite ventilation film with the prepared cotton aphid natural enemy attractant, and heating and sealing.
Description
Technical field
The invention belongs to plant protection attractant technical field, be specifically related to a kind of cotten aphid natural enemy attractant and preparation method thereof.
Background technology
Cotten aphid (AphisgossypiiGlover) belongs to Homoptera Aphidiadae, is one of worldwide important pests of harm cotton.It can sting suction strain juice, causes plant nutrition worsening condition, growth exhaustion; Can drain again honeydew and pollute cotton leaf and cotton fiber, cause mould evil raw, photosynthesis weakens, fading of fiber, and viscosity increases, and has a strong impact on output of cotton and quality.For a long time, cotton aphid control is always based on chemical control, and result in Insecticide Resistance of Cotton Aphids and strengthen, environmental pollution increases the weight of, and agriculture production cost increases, and has killed and wounded natural enemy simultaneously, and make natural world aphid and natural enemy populations disequilibrium, aphid damage is more rampant.
Along with the raising of people's green prevention and control consciousness; high praise is enjoyed with biological preventions such as eco-friendly pest natural enemy controls; and there is the merchandized handling of some natural enemy insects, but due to the reason such as technology and cost, be difficult to the application of scale aborning so far.
Summary of the invention
Insecticide Resistance of Cotton Aphids strengthens, contaminated environment is serious and control the high technical problem of worm cost, provides a kind of cotten aphid natural enemy attractant and preparation method thereof to the object of the invention is to solve easily making that existing chemical control cotten aphid exists.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of cotten aphid natural enemy attractant, it is made up of the component of following mass percent: gaultherolin 1.0-5.0%, phenylacetaldehyde 0.0-3.0%, alpha-terpineol 0.0-3.0%, 2,6-di-tert-butyl-4-methy phenol (BHT) 0.01 ~ 0.1% and absolute ethyl alcohol 60-80%, surplus is distilled water.
A kind of method preparing above-mentioned cotten aphid natural enemy attractant, its preparation process is: be first 0.01 ~ 0.1% 2 by mass percent, it is in the absolute ethyl alcohol of 60-80% that 6-di-tert-butyl-4-methy phenol (BHT) is dissolved in mass percent, add gaultherolin that mass percent is 1.0-5.0% again, phenylacetaldehyde that mass percent is 0.0-3.0% and mass percent be the alpha-terpineol of 0.0-3.0%, stir, finally add distilled water, mixing, namely makes cotten aphid natural enemy attractant; Then the cotten aphid natural enemy attractant will prepared above, in the sack that loading heat-sealed aluminium foils compound breath film is made, adds heat sealing.
The invention has the beneficial effects as follows: the present invention utilizes the external source herbivore-induced volatile of Prof. Du Yucang to make attractant, give full play to the action character of herbivore-induced plant volatiles, can produce the multiple cotten aphid natural enemy such as ladybug, Chrysopa, syrphus fly, aphid parasite, aphid small peak and lure and stick effect, to aphid, there is certain avoidance effect simultaneously, thus effectively reduce Aphis gossypiipopulation quantity, alleviate its harm to cotton plants.Insecticide Resistance of Cotton Aphids strengthens, contaminated environment is serious and control the high technical problem of worm cost to solve easily making that existing chemical control cotten aphid exists, compared with background technology, the present invention has the advantages such as high efficiency, low cost, lasting period long, environmentally friendly, effective minimizing chemical pesticide consumption.
Cotten aphid natural enemy attractant Conservation and development of the present invention beneficial organism, has wide market prospects, will produce significant economic, society and ecological benefits.
