Abstract
The present invention relates to a bollworm moth attractant adsorbed on a carrier and a preparation method thereof. The present invention is characterized in that the bollworm moth attractant is a preparation which is prepared from raw materials of z-11-16 carbene aldehyde, z-9-16 carbene aldehyde, a BHT antioxidant, n-hexane and petroleum ether. The bollworm moth attractant is adsorbed on a carrier which is made of natural rubber or polyethylene. The attractant is matched with a trap, which can lure a large quantity of male bollworm moths and a small quantity of female bollworm moths to reduce mating opportunity; thus, the purposes of preventing and treating insect pests, reducing chemical pesticides, purifying environment and improving preventing and treating effect can be achieved.
Description
The present invention relates to a kind of cotton bollworm moth attractant on the carrier and preparation method of this attractant thereof of being adsorbed on.
Cotton bollworm is a kind of polyphagous pest-insect, it is one of primary pest of cotton crop, it is except that the harm cotton, to vegetables, beans, seeding corn and other crops also has very big harm, growth to cotton, output, quality harmfulness is very big, since the eighties, because the cotton field sprays chemical pesticide in a large number, particularly use organic phosphor and pyrethrin pesticide for a long time, produced pesticide resistance, control efficiency is relatively poor, cause natural enemy to reduce year by year, the ecological balance is suffered serious destruction, and sown areas of cotton reduce significantly, in serious insect pest disaster area, cause the cotton total crop failure, soil property hardens, and quality descends and environmental pollution, so that poisoning, personnel happen occasionally, also the someone adopts the high-pressure sodium lamp trapping method, but just can't use for the area that short of electricity or power shortage have a power failure often, and its investment is big simultaneously, management is inconvenient, trap and kill natural enemy again, so the cotton grower is unwilling to accept this kind product, also the someone adopts branch of poplar trapping method, promptly cut down a large amount of branches from willow, by the smell that distributes, though trapping is this method safety, but in time clear up the worm moth, otherwise cause the worm moth more concentrated, form the severely afflicated area, ruin a large amount of branches owing to will cut, cause deforestation, destroying plants trees makes body, therefore can not apply, the method that adopts gyplure is also arranged, because prescription is unreasonable, induced moth number is less, and effect is undesirable.
Purpose of the present invention provides a kind of cotton bollworm moth attractant and preparation method who is adsorbed on carrier for the shortcoming that overcomes above-mentioned prior art just with deficiency.
Technical scheme of the present invention is the characteristic according to the cotton bollworm moth mating, use bionic method, the suitable component of smell that the chemicals of synthetic and female moth discharge is made attractant, make it a large amount of male moths under the effect of attractant and be entrapped, lost the mating machine meeting, reduce incubation rate and insect density, to reach pest control.
Concrete technical scheme is:
Be adsorbed on the cotton bollworm moth attractant on the carrier, it is characterized in that it is to be made by the following weight proportion raw material:
Z-11-16 carbene aldehyde 1.5-2.2 part
Z-9-16 carbene aldehyde 0.05-0.15 part
BHT antioxidant 0.05-0.12 part
N-hexane 2.0-3.0 part
Benzinum 500-600 part
Carrier 30 as one kind 0-800 part
The raw material of attractant of the present invention is weight proportion more preferably:
Z-11-16 carbene aldehyde 1.7-2.0 part
Z-9-16 carbene aldehyde 0.08-0.10 part
BHT antioxidant 0.08-0.10 part
N-hexane 2.5-2.7 part
Benzinum 550-600 part
Carrier 500-800 part
The raw material optimum weight proportioning of attractant of the present invention:
1.9 parts in z-11-16 carbene aldehyde
0.1 part in z-9-16 carbene aldehyde
0.1 part in BHT antioxidant
2.6 parts of n-hexanes
580 parts of benzinums
750 parts in carrier
Z-11-16 carbene aldehyde, z-9-16 carbene aldehyde is 95% above analysis pure preparation, described benzinum is that the analysis of boiling point 30-60 ℃ and boiling point 60-90 ℃ is pure, and described carrier is cylindric, tubular, sheet, hairbrush shape, square, cuboid, the polyhedron that natural rubber or polythene material are made.
The preparation method of attractant of the present invention, it is characterized in that at first the n-hexane of 2.0-3.0 part being packed into and add 0.05-0.1 part BHT antioxidant in the black out bottle and seal, vibrate and add 1.5-2.2 part z-11-16 carbene aldehyde and 0.05-0.15 part z-9-16 carbene aldehyde after 10-20 minute again and continue vibration 10-20 minute, the benzinum that adds 500-600 part again continues vibration to be made it all to dissolve to make preparation, pour in the carrier of the 300-800 part that is contained in porcelain enamel barrel, make it the absorption of the whole suppressed by vector of preparation till, detect at last, seal in the qualified plastic sack of packing into, be finished product, also preparation can be injected carrier with microsyringe.
The Z-11-16 carbene aldehyde that the attractant that is adsorbed on carrier of the present invention adopts, its structural formula is
Z-9-16 carbene aldehyde, its structural formula is

3, be the solvent that is used for carbene aldehyde and antioxidant, benzinum is a kind of general solvent, requires two kinds of products of boiling point 30-60 ℃ and boiling point 60-90 ℃, and the former is used for the preparation in summer, and the latter is for preparation use in winter, to guarantee better effect.
Attractant on the absorption carrier of the present invention, lure the male moth of cotton bollworm by the smell that carrier continues to discharge, it can be suspended on by outer cover during use, in the middle of overlapping in the trapper below that interior cover and fixed mount are formed, trapper is placed on about 25 centimeters of the cotton tops in cotton field, the smell that male moth discharges at carrier is lured down and is pierced outer cover and be entrapped from interior cover, each carrier can use 30-60 days, at cotton growing stage, 4 carriers of general replacement get final product, can clear up the worm moth of trapper at this, not dead or not air-dry as the fruitworm moth, want buried processing when handling, in case the smell that sends influences trap effect, the 1-2 trapper is placed on general every mu of ground, for the large tracts of land cotton field, can interlock and layout.
Also attractant carrier of the present invention can be suspended on basin top, require carrier,, run into water and fall in the basin and be drowned when the male moth of luring during in parallel flight apart from water surface 2-3mm.
This product uses through the cotton grower, removes a large amount of male moths of trapping, also has a considerable amount of female moths to be entrapped simultaneously, and this may be due to the fertility characteristic of worm moth, after a large amount of male moths is entrapped, and has attracted female moth to be entrapped simultaneously.
Owing to take technique scheme, make the technology of the present invention compared with the prior art have following advantage and effect:
A) the present invention utilizes the mating characteristic of cotton bollworm, effectively lures male moth, lures a small amount of female moth simultaneously, has reduced the mating machine meeting, has reduced incubation rate, protects natural enemy simultaneously, the ecology recovering balance;
B) this product is through Shanxi Medical College's toxicity test, and its conclusion is to belong to low toxicity, to people and animals' nonhazardous effect;
C) properties of product are stable, and are qualified in 40 ℃ ± 2 heat storages, qualified in-10 ℃ ± 5 cold storages;
D) easy to use, not electricity consumption only need be changed 4 carriers at cotton growing stage;
E) consumption is little, and cost is low, and every mu of cotton field only needs 1-2 carrier; the large tracts of land cotton field is staggered layouts; effect is better, uses through the cotton grower, with the method for hanging carrier above the basin; once catch the moth amount and reach 1800/day; catch moth with trapper and once can reach 1300/day, the male moth of the 0.07 hectare trapping first generation can reduce breeding then and reach millions of heads, reduces insect density greatly; reduce the medication number of times, protection soil and environment purification.
