Abstract

The pyralid attractant is compounded with trans-2-hexenal in 0.5-5 vol%, cis-3-hexenol in 0.5-5 vol%, aromatic compound 2-15 vol%, and assistants for the rest. The pyralid attractant may be used in corn field, soybean field, cotton field, vegetable field and other farm land to trap and kill moths of corn borer, leguminous pod borer, soybean leaf rolling borer, etc mainly and may be also used to trap and kill moths of cotton bollworm, deltoid moth and other pests. It has the features of low toxicity, low consumption, high efficiency, simple use, etc.

Description

Pyralid attractant

Technical field: the present invention relates to a kind of Pyralid attractant, relate in particular to a kind of Pyralid attractant that snout moths such as corn borer Ostriniafurnacalis, bean pyralid Lamprosema indicate, bean pod borer Maruca testulalis, beet leukorrhea snout moth's larva Hymenia recurvalis, rice leaf roller Cnaphalocrocis medinalis and noctuids such as cotton bollworm Helicoverpa armigera, three-spotted plusia Argyogramma agnata is had attractive activity.

Background technology: the larva of Lepidoptera moth class insect harms the crops and other plant mostly, as wherein endangering the corn borer of corn, fabaceous bean pyralid and bean pod borers such as harm soybean and Kidney bean, the beet leukorrhea snout moth's larva of harm various vegetables etc., the cotton bollworm of harm cotton, tobacco, various vegetables etc., all be the very big pest of harmfulness, cause very big economic loss every year.Be during larva harm, to use chemical insecticide to the most frequently used method of preventing and treating of these insects at present.Though effectively Pest Control harm of chemical insecticide, the unreasonable use of insecticide often causes problems such as environmental pollution and residue of pesticide, therefore is necessary to seek simple and feasible and insect pest control method safely and effectively.

Summary of the invention: environmental pollution and the residue of pesticide problem brought for the use that solves chemical insecticide, the object of the present invention is to provide a kind of prescription and preparation technology simply to lure the especially Pyralid attractant of corn borer, bean pyralid, beet leukorrhea snout moth's larva, bean pod borer etc. of snout moth, effectively the relevant insects in crop field such as control of maize, soybean, cotton, tobacco with the various vegetables field.

Technical scheme of the present invention realizes in the following manner:

A kind of Pyralid attractant, it is in 100 parts of attractants, prepares by the raw material of following volume parts:

Instead-2-hexenoic aldehyde 0.5-5,

It is suitable-3-hexenol 0.5-5,

Aromatic compound 2-15;

The auxiliary agent surplus.

Described aromatic compound is the mixture of following volume parts compound: benzaldehyde, phenylacetaldehyde, salicylide, phenmethylol, each 0.5-3 part of eugenol or benzaldehyde, phenylacetaldehyde, salicylide, phenmethylol, each 0.5-3 part of benzyl carbinol or benzaldehyde, phenylacetaldehyde, salicylide, phenmethylol, eugenol, each 0.5-3 part of benzyl carbinol.

Described auxiliary agent comprise can and the evenly mixing of above-mentioned each active ingredient, odorlessness and can help the slowly organic substance of release of active ingredient.

This attractant key component is formulated according to the volatile materials in the black poplar blade of the wilting that multiple moth class is had attractant effect, this attractant is by the smell trapping target adult of volatilization, do not contact crops in the use, therefore to crop and person poultry safety, be a kind of new formulation of control moth class.

Good effect of the present invention is:

(1) Pyralid attractant is based on the bionical behavior adjusting control agent of insect to the smell identification test and odor detection mechanism development of odoring substance, female, the male imago of main multiple snout moth of trapping and noctuid are as noctuid adults such as corn borer, bean pod borer, bean pyralid, cotton bollworm, three-spotted plusia, beet armyworms.

(2) compare with the sex pheromone of routine, it is many that Pyralid attractant has the moth of luring kind, and the double characteristics that lure of female, male moth.

(3) Pyralid attractant descends field ovum amount and larva quantity by the trapping adult, and insect is controlled at before the harm, really realizes " putting prevention first " in the control of insect.

(4) the Pyralid attractant main component all derives from plant, and nontoxic or low, usage amount is little, does not in use contact crop, to crop and Environmental security.

(5) Pyralid attractant can be used in crop fields such as corn, soybean, cotton, tobacco and vegetables.

Embodiment:

The invention will be further described below in conjunction with embodiment:

The preparation method of this Pyralid attractant

Mix earlier with the umber mixing by volume of each material, and then with auxiliary agent, divide to be filled in the 6ml vial of bore 12mm every bottle of 5ml.Standby.Table 1 is each component of attractant and a volume parts among 6 embodiment, and the auxiliary agent among the embodiment is 4% aqueous agar solution.

Below the action effect of attractant different formulations is described in detail, but and do not mean that limitation of the scope of the invention.

Implement the place: Agricultural University Of He'nan science and education garden.

Trapper: the basin of diameter 30cm, add a small amount of washing powder in the water, the attractant bottle is suspended in the basin top apart from water surface 1-2cm place.

Experimental scheme: 3 repetitions, district's group is arranged at random.With the auxiliary agent is contrast, and trapper is 25m at interval.

Investigation method: investigate moth kind and quantity thereof in each trapper every morning.Moth and foreign material in the investigation back cleaning basin, and in time supply moisture.

Attractant all carries out in experimental field, Agricultural University Of He'nan science and education garden at the trapping test that lures moth result: embodiment in soybean field, 4 to 7 September in 2002 is (1 repetition) and vegetables field (1 repetition), vega (1 repetition) test in the soybean field, and 1 to 9 August in 2004 is in the soybean field (3 repetitions).Duration of test is not changed attractant.Result of the test sees Table 2 and table 3 respectively.

By table 2 and table 3 as can be seen, each embodiment to lure the moth effect slightly variant because component is different, but all contrast apparently higher than auxiliary agent.Attractant can lure a large amount of Noctuidae of collection and female, the male imago of Pyralidae in the land for growing field crops, this is to reducing the field ovum amount that falls, and insect is controlled at larva has important function before causing harm.In addition, effectively luring of attractant collects apart from also bigger, collected corn borer and the rice leaf roller that does not endanger soybean as luring in the soybean field.Because attractant lures the moth class kind that collects many, and mostly is the polyphagy insect, therefore can use in the various crop field.
