Abstract

The invention relates to a cabbage caterpillar attractant and a preparation method thereof, wherein the cabbage caterpillar attractant is prepared from the following components in percentage by weight: 0.5-2.5% of edible canola, 0.5-3% of honey, 10-30% of vinegar, 5-10% of white wine, 20-40% of cola, and the balance of distilled water. The invention have the advantages that the capital investment in greenhouses is deducted; the costs for cabbage caterpillar keepers and cabbage caterpillar nursing are reduced; the consumptions of water, electricity, disinfectant, and the like are reduced; materials can be obtained conveniently, and the cabbage caterpillar attractant disclosed by the invention can be applied to places with cabbage caterpillars around cabbage lands; and because plastic greenhouses and indoor greenhouses can be used for producing 1kg of cabbage caterpillars, the production cost of cabbage caterpillar granulosis viruses is reduced by more than 60%.

Description

A kind of cabbage caterpillar attractant and preparation method thereof

Technical field

The present invention relates to a kind of insect attractant, refer to especially a kind of cabbage caterpillar attractant and preparation method thereof.

Background technology

Imported cabbageworm has another name called cabbage white butterfly, small cabbage white moth, is the adult form of cabbage caterpillar.Pieris spp Lepidoptera, Sulfur butterfly are worldwide insects, and almost all there is distribution China each province.The larva cabbage caterpillar of imported cabbageworm is one of important pests of brassicaceous vegetable, especially likes wild cabbage, cauliflower, kohlrabi, also can endanger turnip, Chinese cabbage, green vegetables, radish, rape and leaf mustard etc., causes heavy economic losses for numerous vegetable growers.

Cabbage caterpillar is biting mouthparts, to take food blade as main, stays the epidermis of layer of transparent, and 3 ages, above Larva significantly increased, and blade is eaten into hole or incises, only deposit vein, petiole when serious, when be injured seedling stage whole strain withered.Fecal pollution leaf-head and blade that larva is discharged are met rain and can be caused rotten.Killed wound easily brings out soft rot.In recent years, along with the impact of global warming and other factors, the occurrence and harm of cabbage caterpillar is the trend that increases the weight of year by year.

Summary of the invention

In view of this, the object of the present invention is to provide a kind of cabbage caterpillar attractant and preparation method thereof.The method can obtain a large amount of cabbage caterpillar virus raw material, has reduced simultaneously the cost of investment of building green house.

For achieving the above object, the invention provides a kind of cabbage caterpillar attractant, each component of described cabbage caterpillar attractant and percentage by weight thereof are:

Edible rapeseed oil 0.5-2.5%;

Honey 0.5-3%;

Vinegar 10-30%;

Liquor 5-10%;

Laughable 20-40%;

Distilled water surplus.

The invention provides a kind of preparation method of cabbage caterpillar attractant, described cabbage caterpillar attractant follows these steps to preparation: 1) according to good each component of prescription weighing; 2) then edible rapeseed oil, honey, liquor are added in the rustless steel container, a mixed liquor stirs to get; 3) with vinegar, the laughable adding in the rustless steel container, another mixed liquor stirs to get; 4) then with step 2) and 3) mixed liquor of gained adds respectively in the distilled water, be stirred to evenly; 5) with supporting worm cup sealed packaging, put into 4 ℃ of refrigerators, refrigerate for subsequent use.

As preferred version, wherein said edible rapeseed oil is wild cabbage oil.

As preferred version, wherein said vinegar is light-coloured vinegar.

As preferred version, the volume parts of wherein said liquor is 35-45%.

As preferred version, wherein said cola is Coca-Cola.

The present invention has following beneficial effect:

The life habit that the present invention is circled in the air and laid eggs under suitable illumination, temperature, damp condition according to imported cabbageworm is as (being 3-5m at relative fixed space ³) circle in the air and once lay eggs 1, and they are many and more concentrated at the field egg laying amount, be convenient to obtain a large amount of larvas and virus inoculation obtains viral raw material, therefore, attractant of the present invention lures concentrated the laying eggs of imported cabbageworm then to obtain a large amount of cabbage caterpillar larvas of concentrating hatching, concentrating infection virus for next step creates conditions, obtain at last a large amount of cabbage caterpillar virus raw material, reduced simultaneously the cost of investment of building green house, having reduced cabbage caterpillar raises and child care kind worm cost, reduced water, electricity, sterilization medicament equal energy source consumes, in addition, draw materials conveniently, as long as have imported cabbageworm just can use around the wild cabbage ground, can produce 1 kilogram of cabbage caterpillar at plastic greenhouse and indoor greenhouse, finally reduce the cost more than 60%.

Embodiment

Below in conjunction with specific embodiment the present invention is further described.

The concrete prescription of cabbage caterpillar attractant is as follows.

Attractant prescription 1 is made by the raw material of following percentage by weight:

Title content (%)

Wild cabbage oil 2

Honey 1.5

Vinegar 20

Liquor 10

Coca-Cola 30

Distilled water 36.5

Attractant prescription 2 is made by the raw material of following percentage by weight:

Title content (%)

Wild cabbage oil 2.5

Honey 3

Light-coloured vinegar 30

Liquor 10

Coca-Cola 40

Distilled water 14.5

Described cabbage caterpillar attractant follows these steps to preparation: 1) according to good each component of prescription weighing; 2) then wild cabbage oil, honey (commercial), liquor are added in the rustless steel container, a mixed liquor stirs to get; 3) light-coloured vinegar (commercial), Coca-Cola (commercial) are added in the rustless steel container, another mixed liquor stirs to get; 4) then with step 2) and 3) mixed liquor of gained adds respectively in the distilled water, be stirred to evenly; 5) with supporting worm cup sealed packaging, put into 4 ℃ of refrigerators, refrigerate (preferably now with the current) for subsequent use.

Described liquor volume parts is 42%.

Table 1: the attractant effect table of cabbage caterpillar attractant

Test combinations	Every wild cabbage ovum number that falls	Remarks
			The common cabbage field	The 32-47 grain/	The land for growing field crops periphery has nectariferous plant
Use attractant 1 cabbage field of filling a prescription	The 408-900 grain/	Plant rape flower around the land for growing field crops
			Use attractant 2 cabbage fields of filling a prescription	The 1900-4700 grain/	Plant rape flower around the land for growing field crops
Blank	The 7-12 grain/	All around without nectariferous plant

As can be seen from Table 1, use the cabbage field of attractant, its imported cabbageworm egg laying amount is large and concentrated.The cabbage field that adds the attractant prescription is compared as can be known with the common cabbage field, and its imported cabbageworm egg laying amount is above 20 times; Simultaneously can find out that nectariferous plant is also influential to luring of imported cabbageworm.

Wherein, wild cabbage oil, honey and cola mainly have been attracting actions in the attractant, and the effect of liquor and vinegar then is to impel the attractant volatilization.

Below only being the cited preferred embodiment of the present invention, is not to limit protection scope of the present invention, and the equivalence that the those of ordinary skill in the affiliated technical field uses the present invention to do is modified or changed, all with belonging to scope of patent protection of the present invention.
