Problems solved by technology

This is because if the water-based fruit fly protein attractant is added with an effective concentration of thickener in advance, farmers cannot dilute it when they buy it back.
For farmers, the current water-based fruit fly protein attractants on the market are unstable and have a short validity period, and it is inconvenient to add thickeners when using them.
[0006] However, if the thickener is directly added to the protein attractant, it is easy to agglomerate and cause blockage at the nozzle
The solution to this problem is usually for farmers to mix water and thickener the day before application, wait for the mixture to thicken first, and then add protein concentrate and insecticide to the mixed viscous solution before spraying. Attractant spray should only be applied when it is not raining as it washes off easily in rain

Embodiment 1

[0021] Example 1: Comparing the performance of different formulations

[0022] Using yeast powder, soybean powder, skimmed milk powder, xanthan gum, guar gum, ethanol, propylene glycol and polyethylene glycol as the formula of the attractant concentrate, it is prepared according to the formula ratio in Table 1 to form a viscous Liquid mixed liquid, and no precipitation, table 1 is the viscosity of the lure concentrate prepared by each proportion of ethanol base, when propylene glycol or polyethylene glycol is used as the liquid base, the viscosity of the lure concentrate Similar to ethanol base, it is not listed here. Take 10g of the liquid mixture and add it to 200ml of water to simulate the concentration of the gel-type bait spray used by farmers in the field. Stir the mixture for 5 minutes, then let it sit for another 5 minutes. This creates a protein bait gel with properties similar to a normal commercial attractant spray.

Embodiment 2

[0025] Embodiment 2: compare the attracting ability of different formulas to fruit flies

[0026] Observations were made to determine which combination was effective using a combination of Bactrocera dorsalis, protein and thickener mixture, and 0.2% malathion (an organophosphorus insecticide), formulated as follows: Protein 42 parts, 8 parts of thickener, 50 parts of water-soluble alcohol, 0.2% malathion solution is added during use, and the concentration of the attractant in the solution is 10%.

[0027] Take 10 cages and release about 100 newly eclosion Bactrocera dorsalis (mixed sexes) in each cage. Select 30cm long twigs on the peach tree, and each twig is sprayed with 5ml of different types of bait (yeast powder / xanthan gum, yeast powder / guar gum, soybean protein / xanthan gum, soybean protein / guar gum) gum, milk powder / xanthan gum, milk powder / guar gum), and compare with untreated peach branches, observe the mortality rate after 24 hours, see Table 2.

Embodiment 3

[0031] Embodiment 3: Comparison of the attracting ability of different liquid-based attractants to Bactrocera dorsalis

[0032] We selected and prepared two attractant and thickener combinations with good trapping effects to test the effect of different water-soluble alcohols on the attractant effect of Bactrocera dorsalis. The composition of the attractant is soybean powder / yeast powder: guar gum: water-soluble alcohol (ethanol, polyethylene glycol, propylene glycol) is 42%: 8%: 50%. The attractant was diluted with an aqueous solution containing 0.2% malathion at a concentration of 10% by weight of attractant in the aqueous solution of malathion and observed to determine which combination was most effective.

[0033] Take 10 cages and release about 100 newly eclosion Bactrocera dorsalis (mixed sexes) in each cage. Choose 30cm long twigs on the peach tree, spray 5ml of different attractants on each twig respectively, and compare with the peach tree twigs without treatment, ob...

Abstract

The invention provides a liquid attractant for fruit flies, which comprises the following raw materials in parts by weight: 10-60 parts of protein, 2-15 parts of thickener, and 30-70 parts of water-soluble alcohol. The lure uses a water-soluble alcohol instead of water as a liquid base, this water-soluble alcohol-based protein liquid mixture is physically and microbiologically stable, and it thickens quickly when water is added, so there is no need for an "overnight wait" before use ".

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a liquid lure for fruit flies and a preparation method thereof. Background technique [0002] Bactrocera fruit fly is a major fruit pest in China, Southeast Asia, Australia, Hawaii, the Middle East and Africa. These include Bactrocera dorsalis, Bactrocera cucurbitae, Bactrocera tryoni, Bactrocera minax, Bactrocera zonata and others. Fruit flies of the genus Cerephus, particularly the Mediterranean fruit fly (Ceratitus capitata), are major fruit pests in southern and northern Europe and sub-Saharan Africa, Western Australia, Mexico and Hawaii. Fruit flies in the genus Tephritus are pests of cherries and apples in North America. Anastrepha spp. in fruit is a major pest of fruit in Mexico, Central and South America. All these fruit flies belong to the subfamily Tephritidae. Female fruit flies in this subfamily have a strong drive to seek out protein sources and...
